Power Tetris was an addictive Tetris clone by Face Hugger.
Played on its own, Power Tetris was the same as the original game. But when two players attempted the game simultaneously - or up to four players with the use of a simple network cable - a whole new twist was added. Whenever one player successfully filled two or more rows, causing them to 'drop', the others would all have one or more extra rows inserted at the bottom of their playing area. This row would be full except for one missing column.
