Approval Process for New Projects on LEGO CUUSOO


Today we introduce an approval process for new projects, similar to how the Apple App Store handles new app submissions. Our team will check for adherence to the Guidelines and House Rules. We do this so that we can maintain a healthy community by only allowing appropriate projects from the start.

We’ll check for plagiarism, too, but can’t guarantee we’ll catch every instance. You will still be able to report projects that aren’t based on original work, and if we confirm a project uses someone else’s work, we will remove it.

Once we examine your new project, we’ll either approve and publish it, or let you know the reason it was not approved so you can edit it and submit again. Please understand that by approving and publishing your project, our team is not endorsing your project as a product idea.

It’s our hope that adding this review step will provide a better experience than the old setup of allowing you to publish your project and then removing it later if it doesn’t follow the community standards.

Thank you again for using LEGO CUUSOO and best of luck with your projects!


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.


Introducing LEGO CUUSOO International (Beta)

With the introduction of the Design-To-Order process in 1998, has become a pioneer of user innovative product design. Since 2008, has been partnering with The LEGO Group to create a user innovative design system for people to create and market their own LEGO sets in the Japanese market. This revolutionary business model allowed an amateur user with a passion in deep sea exploration to create the world’s first official LEGO set not designed by a professional – the Shinkai 6500.

So far, the LEGO CUUSOO service has been available in Japan only, with sets produced by LEGO for sale in Japan only. While we are pretty happy about our accomplishment in Japan, we know fans of LEGO around the world are eager to use our system to create their own sets, perhaps even a new series! This is why today, we are extremely excited to present to the world the new, international version of LEGO CUUSOO! (in Beta!)


We’ve worked pretty hard on this for a little over 2 months, putting in just the basic required features that will allow you to create and share your LEGO ideas and creations with others. From here on, we’ll be working closely with all of you, listening to all your feedbacks and improve the system to better suit your needs. So, if you haven’t yet, go and check out the site at Registration is by invitation only for now but please leave us your e-mail and follow us on Twitter and Facebook, so we can send invites to you when we’re ready. We can’t wait to see what you can create for LEGO!
