The most successful puzzle games released on the Nintendo Entertainment System are now together on one 16-bit cartridge with enhanced graphics and sound. The gameplay has been left intact, however, so fans of the originals will be able to jump right in. For those unfamiliar with either game, Tetris involves moving one of seven different tetrads down a well. For every horizontal row you complete, a line will disappear giving you points and buying you some time as the pieces keep falling.
Dr. Mario has players moving falling pill capsules to wipe out different colored viruses positioned somewhere within a well. Once you match three colors together (either horizontally or vertically), the virus disappears. Remove all of the viruses and play resumes on a faster, more difficult level. Want to compete against a friend, but can't agree on which game to play? One player can play Tetris on one side while the second plays Dr. Mario on the other! You can then see who's better in a three-round timed challenge. Solo players need not worry -- there are three different computer opponents to face.
