Desktop Games - COLLIDASCOPE
"Collidascope is a delightful twist on Tetris type games. As four differently colored cylinders slowly descend from the top of the playing field, your goal is to have the colors match up vertically, which makes the pair disappear. Your arrow keys can change the order of the colors, to hopefully match all or as many as possible before reaching the last row. Collidascope displays your score and has different levels and optional midi music accompaniment. When the blocks reach a specific height, the game is over."... ZDNet review
