Tetris Giant is an arcade Tetris game played on a large 70" DLP Projection Monitor, and is controlled using giant joysticks with a built-in shaker "rumble" motor, a device that Sega refers to as "Deka Lever" ("deka" is Japanese for large). Tetris Dekaris is one or two-player game with competitive and cooperative modes available. Solo play includes line attack and score attack modes. During competitive multiplayer, clearing multiple block rows makes your rival's speed increase. During two player cooperative play, players can swap pieces with each other by tapping a button on the main arcade cabinet. As in a normal game of Tetris, you move your pieces left and right by moving the stick left and right, and push down on the stick to make the pieces fall into place. Buttons on the top of the joystick can be pressed to rotate your pieces around.

Unique to this game, the Tetris Giant base unit is actually a projector which can optionally be detached from the default screen and projected onto a large wall. Arcade operators are able to disconnect the game from its default monitor and project the gameplay onto a large wall.
