LEGO Ideas


LEGO Ideas, formerly known as CUUSOO, is a Japanese partner of The LEGO Group. They work with the LEGO Group to produce community supported sets. If an idea submitted to the website gains 10,000 (originally 1,000) supporters, it stands a chance of being produced as an official LEGO product.


CUUSOO and LEGO started working together in 2008 and the scheme was launched worldwide on April 23 2011. Originally, it was based solely in Japan, and LEGO CUUSOO projects required only 1,000 supports to be considered for production. In October 2011, it was announced that, starting in October, anyone could upload a creation to, and if their creation receives 10,000 supporters, it will be reviewed by the LEGO Group for a chance to be made into an official LEGO product. Recently, it was announced that you have to be 18 to submit a project. On April 30 2014, CUUSOO was replaced by LEGO Ideas.


  • According to, CUUSOO is a Japanese word, pronounced "KOO-soh", that, when translated loosely into English, means “wish” or to “wish something into existence.” [1]
  • Before April 30, 2014, Ideas was named CUUSOO.[2]
