Tetris (styled TETЯIS) is a puzzle game developed by Atari Games and originally released for arcades in 1988. Based on Alexey Pajitnov's Tetris, Atari's version features the same gameplay as the computer editions of the game, as players must stack differently shaped falling blocks to form and eliminate horizontal lines from the playing field. The game features several difficulty levels and two-player simultaneous play. Atari later ported the game to the NES and released an unlicensed NES version in 1989 under its Tengen brand.
The game ran in B-type mode, where each level was cleared after 10 or more lines, and points were awarded for each empty row at the top of the playfield. Challenges included various patterns of starting garbage and randomly appearing single blocks in the playfield.
