If this game has one downfall, it's that it doesn't end...meaning there's no score to 'beat' because you can just keep racking up the points.
I suppose there's an end to the game if you're that bad at it...but it's not likely.
Another one of the spins off of tetris, the point is to match three of the same colour in a straight line or 'L' shape to take them off the board. When all pieces are off the playing area (there is a constant three-deep wall of blocks surrounding the playing area) you go to the next level.
I have just finished clearing level 30.
