This game seems a great idea as it allows competitors to race against each other in problem solving and as a game it works. Unfortunately the reality is hobbled by poor design which leaves the toy needing to be fully pulled apart every time you finish with it. The movable coloured tiles are not attached and the game does not fold shut. It is easy to lose tiles and fiddly to put it together. It requires a bag or some form of sealable container to keep everything together when not in use. Unfortunately this is a good idea hobbled by either a lack of thought or an income-maximising low budget production which tarnishes the Rubiks brand.
