This is a solid puzzle game, with a 100 levels and a challenge mode where you race against the clock playing tetris stle version of the game.

Multiplayer last about 10seconds but is loads of fun. Clear your screen to send the blocks to the opponents screen. Gets pretty intense.

SOme puzzles are really easy, others take a lot of thought, complete 10 in the stage to unlock the next stage,,,for 20 pounds i think its quite a good deal.

Well I didn't really understand what the game was about from the C3 review (not that I tried too hard), but the game is simply making horizontal lines of the same colour by flipping tiles. Puzzle Mode is frustrating (in a good way!) while Challange is addictive and fun. Multiplayer is hectic and the need for just 1 cart coupled with the puzzle making options make this game great, especially for the cheap
