The LEGO® CUUSOO beta has ended and is now replaced by LEGO® Ideas

Dear LEGO CUUSOO member,

In the fall of 2008, CUUSOO Systems and the LEGO Group teamed up to launch the LEGO CUUSOO crowdsourcing experiment. Initially, the site was only available in Japanese. But the promising results from the pilot led to the launch of the international LEGO CUUSOO beta site in the fall of 2011. Today, the LEGO Group is very happy to announce that the partnership with CUUSOO Systems, has been such a success that we have decided to integrate the CUUSOO concept more closely into the LEGO experience called LEGO Ideas. We are grateful for the many years of collaboration and experimentation between our two companies and wish CUUSOO Systems continued success, building CUUSOO as an open crowdsourcing platform for brands to connect with their fans on

LEGO Ghostbusters Set Revealed at ToyFair New York

Today we gave a first look at 21108 LEGO® Ghostbusters™ to select collector and LEGO fan press at ToyFair New York, and here it is for you as well!

It’s not every year a pop culture classic like Ghostbusters has a big anniversary, so the team here at LEGO CUUSOO has been working overtime to make this set available as soon as possible. 21108 LEGO Ghostbusters will be available for purchase in June 2014 for USD $49.99 / CAD $59.99.

First, some details from the set’s description:

This fun and iconic vehicle from the blockbusting ‘80s movie is fully loaded with all the paranormal detection equipment needed to track down those ghastly ghosts. It also features cool Ghostbusters logo decoration, removable roof, tracking computer and seats for 3 minifigures.

Now, enjoy a first look at this exciting upcoming set:

While LEGO fan builder Brent Waller couldn’t join us at ToyFair, we’ve learned from working with him just how big of a Ghostbusters fan he is. He recently told us; “As a child I would recreate Ghostbusters out of LEGO [bricks]. I had a very primitive Ecto-1, Ecto-1A and the Firehouse as well as all of the main characters with “Classic Space” air-tanks for Proton Packs. As an adult rediscovering my love of LEGO [building], recreating it now was a way of recapturing that unbridled creativity of my youth.” Here’s the man you have to thank for this awesome set in full costume, including Proton Pack:

Exo Suit Progress

For those of you watching closely, yes we did skip a number! The design process for the Exo Suit, our sixth LEGO CUUSOO set, is coming along nicely–however we’re not quite ready to share details. Fan builder Peter Reid is giving us input on the Exo Suit design as we move it toward production, and you can expect more updates on this LEGO fan favorite throughout the Spring.

Announcing the Next LEGO® CUUSOO Set, and Fall 2013 LEGO Review Results

As promised in our review deadline post, here are the results of the Fall 2013 LEGO® Review! We’ve looked closely at each of the seven projects in this review period, and here is what we have decided:

LEGO CUUSOO #007: Ghostbusters 30th Anniversary

We’re thrilled to take the ECTO-1 and minifigure characters from BrentWaller’s Ghostbusters 30th Anniversary project and release them as the next LEGO CUUSOO set. This is an amazing model, and the set will be a fantastic representation of the cult classic film. Supporters know that Brent put a lot of love into this, and the final model, which we can’t reveal quite yet, will be largely based on his original car design. The final design, pricing and availability are still being worked out, and the set will be released later this year, so stay tuned!

Ghostbusters 30th Anniversary

We’re still evaluating the Female Minifigure Set

The LEGO Review Board is still evaluating the Female Minifigure Set project by Alatariel, and we’ll let you know when we have a decision.

All other projects in the Fall 2013 Review periods will not be produced

The LEGO Review Board has evaluated each project according to our decision criteria. We’ve decided that all other concepts in the Fall 2013 review periods (including the Land-Rover Defender 110 project from the Spring 2012 period) will unfortunately not be produced as LEGO sets. However, this decision doesn’t take away from the amazing talent put into these projects or the passion supporters have shown.

Fall 2013 LEGO Review Results

What happened to the other Ghostbusters Project?

We had a special case during this review period: two projects based on the movie Ghostbusters reached 10,000 supporters within the same review period. At the time, we hadn’t fully considered a case like this. Our team looked both at both the immediate choice at hand and also at the precedent our decision sets for the future of the LEGO CUUSOO community.

Ultimately we chose to base this LEGO CUUSOO set on the Ghostbusters 30th Anniversary project for two reasons; this project reached 10,000 supporters first, and our designers decided to base our upcoming set on BrentWaller’s car model. To clarify future cases, we’ve added a Guideline that states if two projects are based on a similar concept, we will consider the project that reaches 10,000 supporters first. See our FAQ for more information on this decision.

How do we make these decisions?

We know you work hard to gain 10,000 votes on a project, but that is really just the beginning of your project’s journey. Once a project reaches that 10,000 milestone, it moves from the Idea Stage onto the Review Stage.

During the Review Stage, a team of specialists within The LEGO Group – including LEGO set designers, marketing and business representatives, and other relevant team members – evaluate the project to determine its potential as a LEGO set. This involves analyzing the votes and information you give us about your project as well as factors such as a project’s playability, safety, and fit within the LEGO brand. This can take months, although exact timing varies due to all the factors involved. Every potential LEGO product, including those developed internally, goes through a process like this and must meet the same standards.

The LEGO Review Board makes all final decisions on which new sets the LEGO Group will release based on CUUSOO projects.

Winter 2014 LEGO Review Results coming Mid-2014

Now that we’re on our new Review schedule, the Winter 2014 LEGO Review is well underway, and you can expect results late Spring. This will be the last of the quarterly reviews and future periods will be labelled “First,” “Second,” and “Third” each year as described in our last post. We’re really looking forward to bringing you the Ghostbusters 30th Anniversary set and considering more of your projects as they reach 10,000 supporters and qualify for review.

Happy building!

Six Winter LEGO Review Qualifiers and a New Review Schedule

Earlier this morning (12:00 a.m. GMT to be exact) the deadline passed for projects to qualify for the Winter 2014 LEGO Review. The last four months has brought us six new qualifying projects, and several fan favorites. Congratulations to everyone who qualified! During the upcoming Winter LEGO Review period, we will consider:

This slideshow requires JavaScript.

What is the Winter LEGO Review?

We take the projects that have reached 10,000 supporters by January 6th and put them into a batch called a “LEGO Review.” From there, we decide which projects will move on to become official LEGO sets, and which are not possible to produce. These review batches have a rolling deadline and now happen three times each year. Check out this Knowledge Base article for more information: What is the “LEGO Review” and what is the current status of projects in review?

Reviews Now Three Times Each Year

The LEGO Review schedule is shifting from a quarterly schedule to three times each year. While reviews will happen less often, this shift aligns the review schedule with the rest of the LEGO Group’s internal processes in a way that allows us to release results more regularly. Review deadlines will now be early May (First Review), September (Second Review), and January (Third Review) each year.

Our goal is to deliver results for qualified projects from the previous period as (or soon after) each new period begins. This means instead of waiting up to nine months for review results like in the past, you’ll see results approximately four months after a review period begins.

2014 LEGO Review Schedule

2014 LEGO Review Schedule

From Passing Review to “Box in Your Hands”

The most intense part of the process comes after we announce review results. During the Production stage, our professional model designers finalize the design, while others create the graphics and building instructions, produce the sets in the factory, and ship them to distribution centers (warehouses) around the world so they’re available to buy. We’re working to shorten production times for you, but we’re still bound by the laws of physics. We don’t have replicators, teleportation, or delivery drones just yet!

Fall 2013 LEGO Review Results Coming Soon

Now that we’re back from the holidays, the LEGO Review Board is finishing up the results of the Fall 2013 LEGO Review. Look forward to these results over the next several weeks.

The First 2014 LEGO Review Deadline is May 5th

Projects that reach 10,000 supporters by 12:00 a.m. GMT May 5th will be included in the First 2014 LEGO Review. You have four months to help your favorite project reach 10k to be reviewed as a potential future LEGO set, so get busy and good luck!

LEGO® NASA Mars Science Laboratory Curiosity Rover Available January 1st

Hailed by NASA as a “miracle of engineering” when it landed on Mars in August, 2012, we’re thrilled to present a LEGO set based on this historic spacecraft. The fifth LEGO CUUSOO set, 21104 NASA Mars Science Laboratory Curiosity Rover, will be available in the LEGO Shop online for $29.99 from January 1st, 2014.

Stephen Pakbaz (“Perijove“), a Mechanical Engineer who worked on the actual Curiosity rover at NASA’s Jet Propulsion Laboratory, designed and submitted the rover project to LEGO CUUSOO in late 2011, to further the educational outreach of the Mars Curiosity rover’s mission, and to encourage greater public support for space exploration. His project reached 10,000 supporters within two weeks of the landing in August 2012, and was selected for production by the LEGO Review Board this June.

The Model

This LEGO version of the highly advanced mobile laboratory features lots of great details, such as 6-wheel rocker-bogie suspension, articulated robotic arm and multiple camera sets, plus a display plate complete with LEGO brick Martian rocks – perfect for testing out the rover’s go-anywhere suspension! Similar to other LEGO CUUSOO sets, the building instruction booklet also includes background information about the fan builder, the history of Mars exploration, and the real Curiosity Rover.

In His Own Words

Stephen Pakbaz recently received his very own Curiosity Rover LEGO sets and would like to share with you this review:

I was extremely excited to receive the official LEGO model of the Mars Science Laboratory Curiosity Rover in the mail. Opening the box was followed by a lot of high-pitched giggling (I was the only one in the room, so I’m not sure who it could have come from!). For me, the building experience was similar to what I felt when the real Curiosity rover successfully landed on Mars. Thanks to everyone at LEGO CUUSOO who made this possible!

The Curiosity rover is one of my favorite and most popular creations. Understandably, I was very interested in what the final model would look like, since the LEGO design process depends on many factors in order to meet their high standards. Ultimately, there is not much of a difference between the official model and my prototype and I can see how the differences add up to significant improvements on my original design. My favorite improvement is the use of the Black Steering Arm, which uses ball joints to connect the rocker-bogie suspension to the swiveling arm on top of the rover body. It makes the rover even more accurate, robust, and easier to put together. It is one of the more rare LEGO elements and if I had known that it existed three years ago, I’m sure I would have used it too.

The instruction booklet was another important part of the set that I was looking forward to. It is a high quality booklet packed with all sorts of images and educational information about the rover, including some of the fascinating history of Mars exploration. My favorite parts are the tidbits added to the margins of the building steps that provide extra information about various components of the rover as you build them.

Above all, the LEGO Curiosity model is not just a display piece. It has a functioning rocker-bogie suspension system and fully articulated robotic arm. It can be used to explore the unknown regions of your house or office. After climbing the outer walls of Carpet Crater and descending into Couch Canyon you will finally be able to determine if your living room was ever capable of supporting microbial life!

— Stephen Pakbaz

The Curiosity Mars Rover was developed by scientists and engineers from the Jet Propulsion Laboratory, which is a NASA facility managed by the California Institute of Technology (Caltech) in Pasadena, California. For more information about Curiosity, visit

Updates to the Guidelines, House Rules, and Terms of Service

Today we’re introducing some updates to LEGO® CUUSOO’s Guidelines, House Rules, and Terms of Service based on things we’ve learned over the last two years. These changes will help focus the contents of your projects toward what we’re able to commercialize through LEGO CUUSOO. We’ve seen a lot of great ideas and models from you, but not everything fits what is practical or possible to make and sell.

Now that we’ve been through a few LEGO Review periods, it’s easier to decide what types of submissions work as potential sets and what kinds don’t. In order to nurture a pipeline that’s more in line with what is possible to produce, these changes narrow the scope of what we’ll consider.

What’s changing?

The new Guidelines, House Rules, and Terms of Service clarify and refine what types of submissions we’ll consider as potential LEGO sets. Our goal is to make review decisions more quickly, which means new CUUSOO sets will get into your hands sooner.


Here are some changes we would like to highlight:

New Guideline What This Means 
Brick-Based Construction Toy Projects Only Please only create projects suggesting standard LEGO sets and not new parts, software, websites, apps, or non-LEGO brick based products (backpacks, mugs, etc).
One Project = One LEGO Set Projects should only suggest single stand-alone LEGO sets, and not a series of products or a playtheme.
No Minifigure Series or “Battle Packs” We no longer allow projects suggesting solely minifigures, minifigure collectibles, “battle packs,” “character packs,” etc.
Only Use Authentic LEGO Parts Please do not include non-LEGO brand bricks in your projects, whether from competing brands or after-market customizers.
No Company Logos or Team Mascots We no longer consider projects consisting of company, team, or organization logos or mascots.
Please Don’t Use Our Logos You may not use the LEGO Logo (or represent it), or any of our other logos in a way that could imply we endorse your project. See this guide for clarification.

CUUSOO Sets and Potential Playthemes

LEGO CUUSOO is set up to evaluate and release single LEGO set concepts that reach 10,000 supporters, and not playthemes, product ranges, or parts. The LEGO Minecraft concept proved so popular that the LEGO Group decided to release more sets as a continuation of our license agreement with MOJANG. This is really exciting because even more people will be able to celebrate their love for building, both with LEGO bricks and in the Minecraft universe!

While this naturally gives hope that your concepts could also make it to “theme status,” our team still sees future scenarios like this as incredibly rare. Nevertheless, it is a possibility, so we’ve also added Guidelines language that clearly states we don’t offer credit or compensation for any potential follow-up sets, since those are developed by us outside of LEGO CUUSOO.

New House Rules

It’s occasionally necessary to remind people of our expectations of respect, etiquette, and fair behavior, so we’re adding these two House Rules:

  • Respect Privacy. You may voluntarily link to your social media accounts on your profile but please do not share your email address, phone number, or other contact details. Never share someone else’s personal details that are not readily available on their LEGO CUUSOO profile.
  • One Account Per Person. LEGO CUUSOO is designed for creative people who play fairly and honestly. Secondary accounts will be removed when discovered and users who operate multiple accounts risk being permanently banned from participation. Please refrain from creating “team” or group accounts.

Guidelines, House Rules, and Terms of Service, oh my!

We refer to these a lot, but what is the difference between them? Here’s how these documents relate to each other:

CUUSOO Guidelines House Rules Hierarchy - Cropped

Moving Forward

Our team has learned a lot over the last two years of the LEGO CUUSOO Open Beta. We’ve browsed your great projects and ideas, and have had the privilege of evaluating those that make it into the LEGO Review. We’ve learned volumes about what’s possible to produce and what isn’t within the CUUSOO framework.

As a result of these changes, there are now many existing projects we won’t consider anymore. Many projects that no longer fit will soon be removed and their creators notified. Owners of projects that can be modified to fit the Guidelines will also be contacted. To simplify the administration of this change, projects with over 1,000 supporters will have until December 31 to make the necessary changes, and projects under 1,000 are asked to make the necessary changes before they reach 1,000 supporters.

Know that we can’t express enough how much we appreciate the passion and energy that goes into each and every one of your submissions, even if we’re not able to make them. Thanks again for enthusiastically sharing with us the things you would like to see made into future LEGO products and we’re looking forward to making more LEGO wishes come true as we grow.
