Announcing LEGO Minecraft™ Micro World, the third LEGO® CUUSOO product.

We’re thrilled to give you the first look at the third LEGO CUUSOO product, 21102 LEGO Minecraft Micro World. The Minecraft project was the first to reach 10,000 supporters on LEGO CUUSOO and pass the review required to become a LEGO product.

The Model
Each box includes parts to build four cubic modular vignettes that you can connect to recreate the Minecraft experience in LEGO bricks. One Minecraft block is equal to one 1×1 LEGO plate with a tile on top–not a perfect cube, but the best approximation at the chosen scale.

The set includes two of Minecraft’s most iconic characters, Steve and a Creeper, represented as “Micro Mobs.” The surface of the modules comes off to reveal mines and hidden resources beneath. You can build your own landscapes, stack cubes on top of each other, and build the world of Minecraft as you wish. LEGO Minecraft Micro World presents a modular standard for building a Minecraft world that can be configured any way you like.


The Design Process
LEGO Minecraft Micro World
was developed in collaboration with four LEGO fans: Chris Malloy, Michael Thomas (suparMacho), Kyle Tingey (koalaexpert), and Bjarne Panduro Tveskov. These fans developed their own concepts alongside LEGO designer Steen Sig Andersen and the LEGO CUUSOO team, and helped us shape the product into its final version.

The concept has taken quite the journey from the original concept images at a 2×2 brick scale. Once the group saw the micro-scale concepts, there was no doubt that this was the right direction for the product. Bjarne Panduro Tveskov, himself a former LEGO model designer, said the scale “packs the most Minecraft DNA into the model per LEGO brick,” and we all agreed.

Now Entering Production
Now that the product design is complete, the LEGO Minecraft Micro World is entering production. Over the next couple months, look forward to highlights of the design process and maybe even a sneak peek into the factory as it comes off the line. The set is in the middle of a record six-month journey from concept to finished product and will be available for you by summer 2012.

Pre-Order Yours Today
You can pre-order today and be one of the first to receive LEGO Minecraft Micro World when it ships this summer. LEGO Minecraft Micro World is available for pre-order exclusively through Mojang retail partner J!NX for $34.99. To pre-order yours, become a fan of LEGO Minecraft on Facebook. You’ll also be able to buy the sets this summer via and select LEGO brand retail stores.

Mojang will donate the 1% proceeds from LEGO CUUSOO to charity.

Updates to the LEGO CUUSOO Terms of Service and Guidelines

Over the last couple weeks, we’ve made some key updates to our Guidelines, House Rules, and Terms of Service, which we have outlined in two earlier posts here. We’re making these changes to provide a foundation so we can continue building LEGO CUUSOO and help your projects succeed. Here we’ll walk you through the most significant changes. You also might want to review the entire Project Guidelines and House Rules so you are familiar with all of the changes.

Improving Project Quality
Many of the projects on LEGO CUUSOO are very high quality and we are amazed at the talent and creativity expressed here. We’re working to help increase quality on some of the lower quality projects as well. The new Guidelines, House Rules, and TOS are motivated in large part by the desire to build LEGO CUUSOO into a vibrant, creative community of high quality ideas that have strong potential to become LEGO products.

A Focus on Original Work
LEGO CUUSOO exists to allow you to share your original ideas and to help you make your LEGO wishes come true. LEGO builders of all ages put a lot of effort into their creations, and naturally take pride in them. It isn’t fair for you to upload someone else’s work as your own. Therefore, LEGO CUUSOO only allows users to create projects based on their own work, without exceptions.

Projects We Allow
Here are some details on the types of projects that are welcome on LEGO CUUSOO:

  • Original Projects – If you submit an original idea that you conceived yourself, it reaches 10,000 supporters, and we opt to produce it, you will receive the standard 1% royalty.
  • Projects Based on Third-Party Intellectual Property – We welcome projects based on third party intellectual property (such as movies or games). If one of these projects reaches 10,000 supporters, we will handle the necessary licensing arrangements (so don’t worry about that). Like any LEGO CUUSOO project, you must provide your own original model and cannot use anyone else’s work. If we produce a product based on your project and original model, you will still receive the 1% royalty.
  • Theme-Based Projects – You are welcome to create projects to introduce a new LEGO theme or product line. (Note: We initially restricted these projects with the new Guidelines update, intending that such a rule would improve project quality by making projects more focused. However, we recognize the effort you are putting into projects like these and will instead work to help increase quality by offering our own tips and suggestions that will encourage others to support).
  • New Part or Element Projects – It is difficult to quantify up-front how many kits in which a part will be sold, and over how many years. We’ve decided it makes more sense to compensate part designs with a one-time flat fee that we determine. That fee could vary, which is why we don’t define it up-front, but it will be fair and proportionate to what the royalty would be for a LEGO set project.

Removing “Bring Back” Projects
LEGO CUUSOO is designed for you to submit your own new and original ideas to be considered as potential LEGO products. Since “bring back” projects are links to retired products the LEGO Group owns, they aren’t original or new and aren’t appropriate for CUUSOO. We will be contacting owners of “bring back” projects and removing them over the course of the next week.

Protecting Our R&D Efforts
There’s naturally a possibility that you could post a Project without knowing the LEGO Company is already developing a similar product. Because our product development timelines span months and even years, we ask that you understand overlaps of this nature are unintentional on our part. By participating on LEGO CUUSOO you agree that if this happens, you will not claim infringement against us. In return, we promise you that we will not take this clause in the TOS and Guidelines as license to be opportunistic, and will respect instances where your projects predate our efforts.

Creating a Positive and Respectful Environment
LEGO CUUSOO is meant to be a fun and respectful atmosphere. We’ve established the House Rules so you can help us keep it that way. The House Rules have two important updates this week:

  • Please keep your comments coherent. Refrain from using incomplete sentences, ALL CAPS, txtspeak, chatspeak, and the like. Respect other users by writing comments that are easy to understand.
  • We don’t allow advertising, religious preaching, or political campaigning and we do not allow content that is intended to put down anyone else’s political or religious views. Also, LEGO CUUSOO is not a format for you to advertise your business, employer, or non-profit. For context and explanation, refer to the House Rules.

Shifting Gears
We’ve made these changes to provide a foundation to help your projects succeed. We believe the new Guidelines communicate more clearly the types of projects that we are looking for and provide a clear baseline from which we can encourage high quality ideas and curate content appropriately. Now that these updates to the Guidelines and Terms of Service are in place, we’re shifting gears toward helping you increase the quality of your projects and attract more supporters.

Happy building!

Responses to Questions Regarding Changes on LEGO® CUUSOO

We saw your comments on LEGO® CUUSOO regarding the coming changes to the site. Several of you expressed questions and concerns regarding our post yesterday about the new requirement that from January 12, users must be 18 or older to have a Project on the site.

One user created a new Project called “No to 18+!” to protest the coming change. Other users commented there expressing opposition, support, questions, and concerns. We were really grateful to see that the comments were polite and civil, even from those who disagreed. Thank you for keeping comments constructive, and thank you for being so passionate about sharing your LEGO ideas with us through LEGO CUUSOO.


Our team read every single comment within the “No to 18+!” project, took note of the concerns you expressed, and used your questions as a basis for this response. The project itself has now been removed, because it is not a LEGO product idea. We allowed you some time to vent and ask your questions there, and now we are responding here on our blog.


LEGO CUUSOO is in public Beta, which means we’re encouraging users to participate while we continue working out bugs and making feature improvements. By inviting your participation now, we’re able to learn much more about what will make a great site and experience than we would with a closed test site.  Thanks for your patience through the inevitable snags and glitches during the beta process.

Here are some questions gleaned from the comments, along with our responses:

Q: I am under 18.  Can I still support projects on LEGO CUUSOO?

Yes. Users who are at least 13 years old are welcome to support others’ projects and comment on them.

Q: Why is the age to create a project being raised to 18?

During the course of writing our new Terms of Service, due to be published after January 12, we have determined that users must be 18 years old or older to enter into the agreement with us.

Q: Will I be able to restore my project once I turn 18?

Yes. We are not deleting your projects, we are simply un-publishing them from the website. You will be able to re-publish your project once you are 18.

Q: If my project is unpublished, when I turn 18 will it still have the supporters I have already earned?

Yes. You will not lose your supporters when your project is un-published.  When you re-publish your project it will have the same number of supporters you had before.

Q: I am over 13, but under 18. May my parents create an account on LEGO CUUSOO and may I upload projects through that account?

If your parents create an account on LEGO CUUSOO, the account belongs to them and the LEGO CUUSOO Terms of Service apply to them. Therefore, our agreement regarding the necessary commercialization rights to any projects created is with an individual who meets the legal requirements.

Q: I am under 13. May my parents create an account that I can use on LEGO CUUSOO?

We’re sorry. LEGO CUUSOO requires individuals to be at least 13 years old before they can create an account.

Q: Kids and teens are the LEGO company’s target audience. Why are you restricting them, and if kids under 13 can’t vote, how will you know what they want?

Legally we cannot allow users under 13 to participate on a website that is open to all ages unless we comply with very specific rules to protect them. LEGO CUUSOO is intended for a grown-up audience. We believe even though project supporters are over 13, the amount of support required to produce a product is significant enough that it demonstrates demand and a market opportunity upon which we can make an educated decision to develop and release a new product.

Q: How will you give credit to users when more than one person has uploaded a Project related to a particular idea?

Other crowdsourcing sites that invite users post their ideas for product development have created methods to solve this issue and allow multiple users to contribute to a common idea. Some of these systems weight contributions based on effort and value added, and we think that’s a smart approach as long as it is transparent to you. We are investigating how we wish to approach this on LEGO CUUSOO.

Q: I’m concerned that another user will take my idea. How are you going to handle that?

There are two types of “ideas” submitted to LEGO CUUSOO; “generic” ideas and unique ideas that you conceived entirely yourself.

Many projects are “generic” ideas of things that already exist in the world built with LEGO bricks; for example a LEGO elephant, or a LEGO vehicle from a movie.  If you post your version of something generic, we won’t stop someone else from posting their own version.  This means the value of a generic project is in the substance behind your work, combined with the popular support. If two users publish the same generic idea and one does a better job communicating and gaining support, it is only fair to give weight to the better executed project.

In short, you can’t squat a generic idea and be the only person allowed to submit that concept to LEGO CUUSOO.

If you come up with your own unique creation (vehicle, story, etc.), that is not based on something generic (or someone else’s intellectual property), that idea is yours and it is unique.  We won’t allow someone else to submit your idea, change it a little, and benefit from it.  We’ll know it is yours based on when you submitted the project and the fact that it is not based off of someone else’s LEGO creations on the Internet.

Q: How do you plan to address the number of low quality projects that are on LEGO CUUSOO?

We have been discussing various solutions to the issue of low quality project submissions. We believe in a two-sided approach: The first solution is to educate the community on elements of a good project, providing examples and how-to guides. The other approach is to review individual projects for quality and moderate accordingly, or to consider moderating all new projects for quality and adherence to the Guidelines before they are posted to the site.  We will continue developing our approach to project quality and keep you informed.

Thank You

Thank you for your patience as we’ve taken the time to consider and respond to your questions. We hope the above responses provide some clarity.

In the coming weeks, we will expand on the thoughts introduced here regarding project quality, what makes a unique project and things you can do to improve your project submissions.

We understand that some of you are disappointed by the news of the new project age restriction, and we’re sorry for being the bearers of bad news. There are certain rules that we must follow to provide this opportunity to submit your product ideas and see them produced as official LEGO products. Thank you for understanding that we truly appreciate LEGO fans of all ages.


Coming Changes to LEGO CUUSOO

LEGO CUUSOO has seen quite a bit of early success since opening up to a public beta just three short months ago. Hundreds of new projects have been started, with many of them being very high quality, creative, and intriguing. Witnessing the enthusiasm for the Minecraft project from Mojang and the Minecraft community, we’ve learned what can happen when you throw the gates open wide and encourage people to freely post whatever they like on a site that’s still very decidedly has “beta” level features.

We really appreciate all of the enthusiasm you have put into projects and comments. However, with the fun projects, comments, and collaborative efforts but we’ve also seen some undesirable behaviour. We believe very little of the undesirable behaviour came with truly malicious intent. To encourage the behaviour we want, we have to be sharper at setting standards, setting examples, and shaping the constraints of the site.

We are now rolling out a series of changes to LEGO CUUSOO, the Terms of Service, and the Guidelines as the first step of a longer-term effort to foster the vibrant and creative community we are looking to build here. The changes you will see are a part of a short-term effort to fill in some of the gaps we’ve uncovered on the site since it opened. The gaps have allowed for frequent plagiarism, negative comments and comment spam. We are also actively working on improvements to the website, design, user experience, and crowdsourcing model that will benefit you in the future, though these major changes will take a bit longer before they are ready.

Today: Removing Users Under 13 Years Old

Though the site rules and Terms of Service clearly state all users must be 13 and older, we discovered a technical glitch on the sign-up forms that did not prevent children under 13 from signing up. The form has been fixed and we are removing these users’ accounts and deleting their personal data to comply with the US Child Online Privacy and Protection Act (COPPA).

We apologize for the error that allowed for this in the first place and the resulting disappointment that this will cause to the users affected. and the LEGO ID system has complied with COPPA for years, however LEGO CUUSOO is a site designed for adults and purposefully developed outside of the LEGO ID system.

If you are under 13, you are welcome to browse the LEGO CUUSOO site, but cannot create a personal account to vote, comment, or create projects.  If you are looking for fun LEGO activities on the Internet, is specifically designed as a fun environment for kids of all ages. Please ask your parents to help you create an account there.

Next Week:

Raising the Project age to 18

From next week Thursday (January 12), you will need to be at least 18 years old to create a Project on LEGO CUUSOO. As we considered the various changes needed to the Terms of Service (TOS), we have determined that users must be at least 18 to enter into a legal agreement with the LEGO Group that allows us to produce their idea as a LEGO product should it reach the 10,000 supporter threshold.

If you are under 18, your projects will remain online and visible until Midnight, January 12 GMT.  You have between now and then to save any images and text you’ve uploaded to LEGO CUUSOO.  After that date, your projects will be unpublished, and you will not be able to re-publish them until you are 18 (according to the birthdate you have provided us).  Once you turn 18, you’ll be able to re-publish your projects—and we hope you choose to do so!

If you are under 18, you’re still welcome to have an account on LEGO CUUSOO and you may keep supporting others’ projects and are welcome to comment on them.

Updating Guidelines and Adding House Rules

We will release the new Guidelines that provide clearer guidance for creating your Projects. Also, we’ll add the new House Rules that were originally posted to the CUUSOO blog to the website, so we can continue to encourage positive behavior on LEGO CUUSOO.

Improving Project Publishing and Reporting

When users publish new projects, they will be asked to check a series of boxes that confirm they have read and agree to certain provisions within the Guidelines. It is our hope that this quick additional step will cut down on the number of projects that violate the guidelines going forward. We’re also improving the reporting mechanisms for projects; You will now be able to specify the type of inappropriate content when reporting Projects, so we can better handle issues as they arise.

Updating the TOS

We are improving the Terms of Service and basing them on an updated LEGO template. In conjunction with the new TOS, we have collaborated with the ReBrick team and are implementing their provisions and web form for submitting a formal take-down request, similar to what YouTube does for copyrighted videos.

Improving Moderation Capabilities

We have discovered opportunities to improve how we moderate on LEGO CUUSOO, to help our users receive a better experience, and improve our moderation response times.  Most of these positive changes should be transparent to you, and you will start to see more consistent and timely moderation on LEGO CUUSOO as we add to our capacity.

In the Weeks and Months to Come

In the medium and long term, we are looking for ways we can encourage users’ wishes for various LEGO ideas they see posted online to be made into LEGO products. We’re also looking into better ways to facilitate collaboration between users so that good builders can team up with good promoters to shape and grow the fan base of individual ideas.

We’re also actively working on a redesign of the LEGO CUUSOO site, based on what we have learned from the current user interface and the way people use the site. While we wish that we could take what we know now and implement it overnight for all of you, design and development takes time, so we’re thankful for your patience.

Finally, we understand that some of these changes will make certain people happy and other people upset. It’s our goal to learn, continuously improve, and make the decisions we believe are right to build a vibrant, creative community that yields many excellent user-created LEGO product ideas. Thank you for your continued interest in participating with us in this great experiment for product co-creation, and we’re looking forward to your input and your ideas!

Thank you,

Tim, Ken, Troels, Paal and the LEGO CUUSOO Team


New LEGO CUUSOO House Rules

As we look forward to revealing and launching Hayabusa and sharing the results of our LEGO Review of Minecraft, we’re happy to see all of the creativity you are putting into your LEGO CUUSOO projects.  There have been some great new projects over the last few weeks and some cool new content on some of the older and more popular projects, too.

LEGO CUUSOO is striving to be a constructive environment where people can share their creativity and new ideas.  The site remains in beta, which means that we are still developing and testing the site and making tweaks to the rules and crowdsourcing model so the site fulfills our vision.  Thanks for understanding that and adapting with us as we learn what behavioral standards make for that constructive community.

Unfortunately we’ve seen some undesirable behavior in some of the projects here on CUUSOO.  Users have been uploading others’ ideas as their own, spamming in the comments, trolling, and even using the comments as a chat room rather than to discuss the projects themselves.  As a result, we’ve taken some disciplinary action as we’ve seen fit.


Site updates are coming

We have been working on a series of updates to the Guidelines and Terms of Service that make it more clear what types of projects and what kind of activity we want to encourage here.  These are due for release in early January.  We’re also going to make it a lot easier and more straightforward to report stolen content.

While we hoped the tone of conversation on LEGO CUUSOO would stay constructive until then, it has not, so we are implementing the new House Rules portion of the revised Guidelines now (based somewhat on the House Rules on LEGO ReBrick) and will follow up with more comprehensive and clear Project Guidelines soon.


It is your responsibility as a user to keep your interactions fun and respectful, so the atmosphere remains positive with a focus on sharing new ideas for LEGO products. To make sure that everyone has a good time, we have made these common sense house rules:

  1.  Be respectful.  When you comment on others’ models, keep your remarks positive.  Even when you have suggestions for improvement, keep a constructive and respectful tone.  Don’t be offensive, creepy, abusive, humiliating or intimidating and don’t harass or impersonate others.  Please also keep your remarks on-topic.  This is not a discussion site, comments on LEGO CUUSOO should be focused around the Projects you are supporting.
  2.  Play nice.  LEGO CUUSOO is to be a good, clean environment.  Don’t create Projects related to alcohol, drugs, tobacco, sex; or any kind of content containing realistic or extreme violence, or content intended to shock or disgust.
  3.  We will step in if we must.  We reserve the right to remove any comments or content that is in violation of these rules. Repeated or excessive violations of the House Rules will result in a ban from LEGO CUUSOO.


In addition to the House Rules above, here are some examples of good behavior and bad behavior to help you know what is acceptable and what is not:

Keep comments on-topic:



Great model!  I love the use of cheese slopes.  Have you considered adding XYZ to it?

Cool.   Hey, come and support my project about LEGO Galidor.

Keep comments constructive:



This is a good effort, but the color scheme is not that great.  Try using fewer colors.  Stick to two main colors with a couple accents.  It’ll look better, and I think you’ll get more supporters that way.  Good luck!

This sucks.  I’d never vote for a rainbow warrior like that.

Please don’t do these things:

  • Don’t use the comments as a chat room: “Hey everyone, let’s have a team discussion. Everyone comment below this now.”
  • Don’t attack or threaten: “You’re a loser, Bob.  I’m going to come and get you.”

Thank you for working with us to keep LEGO CUUSOO a positive atmosphere, and thanks for your patience as we make a couple necessary adjustments.  Most of all, thank you for sharing your creativity here on LEGO CUUSOO and good luck on your journey to 10,000 supporters for your projects!

Minecraft update set for after Christmas

The holidays are fast approaching, and the elves are making sure store shelves are fully stocked with LEGO sets so that kids (both old and young) can open boxes with that familiar rattle this year…

We know many of you are itching for a verdict and update on a Minecraft LEGO product.  We originally said this would be a 1-2 week timeframe, but since this backs up to Christmas, turns out we were a little ambitious with that estimate.  The LEGO Jury is continuing our evaluation through the break and we anticipate having an update after the holidays.  Thanks again for all of your interest in Minecraft and LEGO sets.  We wish you a great time celebrating with family and friends this coming weekend.

Minecraft project achieves 10,000 supporters on LEGO CUUSOO


A big congratulations is in order to Mojang for securing the required 10,000 supporters on LEGO CUUSOO in hopes of seeing their LEGO wish become a real product!  We officially advance this project to the Review phase.  It is still too early to say whether a Minecraft play set will become a LEGO product as it still needs to go through a review and approval process to ensure it meets our usual LEGO standards, but it is certainly a lot closer (more about that below).

The passion of the Minecraft community is now very obvious.  This latest project slowed our servers to a grind and took them down three times as we adjusted to the heavy traffic.  So, we’re listening. ;-)

We never expected a project to meet the 10,000 threshold this quickly while the website is still in beta.  For a bit of perspective, our first launch, the Shinkai 6500, took 420 days to reach 1,000 votes in Japan.  Hayabusa, our second, took 57 days for the same.  This project took only 48 HOURS to reach 10,000 supporters worldwide.

We’re also pleased with how Mojang and the builders behind the original fan-created Minecraft project, “koalaexpert” and “suparMacho,” worked together in a collaborative and giving spirit. It’s a great story, and our hats are off to you for that.

What happens now?

This project moves from the Idea stage to the Review stage. A “LEGO Jury” composed of designers, product managers, and other key team members will examine the idea. We’ll build concept models and determine if the concept meets our high standards for what it takes to be a LEGO product, including playability, safety, and fit with the LEGO brand.

Whie the fit sounds obvious to Minecraft fans (Minecraft blocks and LEGO bricks look similar, so of course it’s a fit), every single LEGO product goes through a similar process and must meet the same standards.

This review is a 1-2 week process. When finished, we make a “go/no go” decision to develop and sell Minecraft LEGO products. If it is given a “go,” the project then enters the longest phase; the Development phase. During this time, LEGO model designers refine the product and develop it for release, we create the product materials (box, instructions, marketing), and get everything ready for a production run. This takes several months.

One more thing.

We know 1-2 weeks is a long time to wait, so we’ll try to work fast. Maybe not as fast as you were getting to 10,000, but we’ll see. We appreciate your enthusiastic support!

For more information, see the Minecraft press release by the LEGO Group.
