Run-of-the-mill puzzle game that tried to cash in on the Tetris craze like so many others of its day. It's not bad, it's not good. It's OK for some short-term entertainment but I can guarantee you won't be playing it long. The object of the game is to drop the different-colored blocks that come down the conveyor belt into stacks of three or more of the same color. The longer you play the faster the blocks come down the belt, thus providing ever greater challenge as you progress.
