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.
As of November 2014 the game cannot be purchased anymore. The official site has been replaced with a message "Tetris Zone is unavailable. Please visit the official Tetris website."
