Class 4 article

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.


The logo for LEGO Cuusoo

CUUSOO and LEGO began 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 the same month, anyone could upload a creation to their website.[1] 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. On April 30, 2014, CUUSOO was renamed to LEGO Ideas.

  • Prior to April 30, 2014, Ideas was named CUUSOO. [1]
  • CUUSOO (空想; pronounced "KOO-soh") is a Japanese word that, when loosely translated into English, means "wish" or to "wish something into existence." [2]
  • Even though LEGO rejected the Tumbler, Ghostbusters Firehouse HQ, RMS Titanic, The Wizard of Oz, The Goonies and Portal projects, they did produce sets of the Tumbler, Ghostbusters Firehouse HQ and RMS Titanic and included The Wizard of Oz, The Goonies and Portal as subthemes in LEGO Dimensions.
