The player controls falling shapes in the classic game of Tetris. Controls use the left right down arrow keys and up arrow for rotation. The spacebar instantly drops the shape down to the game field. The goal is to complete horizontal lines so they disappear and award points. With each new level the falling speed increases making the game harder. The player sees three dimensional glowing blocks that rotate smoothly while falling. When the field fills to the top the game ends and a result screen appears. Great puzzle game for developing spatial thinking and reaction speed.
