Most attempts to tamper with the basic gameplay ofTetrishave fallen flat on their faces, butTetris Plusis actually a  decent take on the timeless classic. You can tackle a basic solo game ofTetris, challenge a friend in two-player mode, or go directly to  the best portion of the game: puzzle mode.In puzzle mode, players  control blocks as they descend from the top to the bottom of the screen.  As they fall, you can spin blocks so that they land next to  corresponding colors at the bottom of the screen. Gameplay is just like  the original only with a few major twists. The bin that holds the pieces  at the bottom of the screen starts out partially filled, while a little  professor character climbs on top of the stack. Your job is to clear  lines of blocks so that the professor can reach the exit at the bottom  of the bin before a spiked ceiling smacks him in the head. Two players  can also duke it out in puzzle mode, sending cleared lines to their  opponent's bin. This isn't the best version ofTetriswe've ever  played, but it does still manage to offer a lot of entertainment for its  low price.--T.
