How to Play

Move and rotate the falling pieces so they fit together. A full row disappears and gives points. Keep the stack away from the top of the board.

Keyboard Controls

• Left / Right arrows: move the piece sideways.
• Down arrow: soft drop.
• Space: hard drop.
• Up arrow or X: rotate clockwise.
• Z: rotate counterclockwise.
• C or Shift: hold the current piece for later.
• P or Escape: pause.

Touch Controls

On phones and tablets, use the on-screen buttons below the board. The wide buttons handle soft drop and hold. The center drop button places a piece immediately.

Game Modes

• Beginner: slower start and simple settings.
• Marathon: keep clearing rows and chasing a high score.
• Sprint: clear the target rows as fast as possible.
• Ultra: score as much as possible before time runs out.
• Zen: relaxed play with no pressure.

Revives

In solo play, a game-over screen can offer a revive. If rewarded ads are available, the rewarded revive continues the same run after the reward is completed. The math revive asks one short calculus question and allows two wrong guesses per game-over.

Friend Battle

Online battle creates a room code that a friend can join from another device. Same-device battle splits the screen in half so two players can compete on one keyboard.
