Tetris Worlds was the game that became the basis for the Tetris Guideline.
Like other Guideline games, Tetris Worlds has a relatively long lock delay with infinity, a hard drop without lock delay, and full SRS. It shows three next pieces on GBA and six next pieces on other platforms. Unlike later games, the game had an autorepeat feature for the rotation button; holding down the rotation key kept the piece spinning continually. The game was also the first Tetris game to feature an American female voice whispering to you during gameplay.
