Grand Teton 1.7.1
Grand Teton is a Tetris game for Macintosh with 19 different 4-tile shapes which you must rotate and position so that they will drop into a pit and form a line all the way across.
The lines completed will disappear.
As you make more lines disappear, the game speeds up, making Grand Teton more challenging. The game ends when a tile cannot enter the pit because the other tiles are piled to the top.
The game also includes a "highest score" function, but to make this function work you must complete 6 lines in the game.
