How to Play

• Stack falling tetrominoes to fill complete rows.
• Filled rows clear and earn points. Don't let the stack reach the top.
• Use Hold to stash a piece for later (once per drop).

Controls

• Arrow keys: move/rotate
• Space: hard drop (instant)
• ↓: soft drop (extra points per row)
• C: hold piece
• P: pause

Scoring

1 line = 100 × level, 2 = 300, 3 = 500, 4 (Tetris) = 800 × level. Speed climbs each level.
