Tetris Zone

Tetris Zone is an official Tetris game for the Macintosh platform and was released as an Universal Binary (for Intel- and PPC-Macs). A Windows version is also available.

It was one of the first games that attempted to limit the effects of T-spins on the game, by eliminating the recognition of T-spins triples. However, singles and doubles that use the TST twist are still recognised.
