The timeless falling-blocks puzzle: rotate pieces, complete lines and clear them. Every 10 lines the level rises and blocks fall faster. How long can you survive?
OR SWIPE: ← → move · ↑ rotate · ↓ drop
Blocks fall from the top. Move them with the arrow keys (or WASD), rotate with ↑/X, hard drop with space, and hold with C/Shift. Complete a full horizontal line to clear it — the goal is to keep the stack from reaching the top.
The game runs entirely in your browser. Nothing is tracked or sent anywhere — your best score lives only on your device.
Left/right arrows (or A/D) move, up arrow (or X) rotates, down arrow (or S) soft-drops, space hard-drops, C (or Shift) holds a piece, P pauses.
Fill a complete horizontal row with blocks — the row disappears and everything above drops. Clearing 4 lines at once is a 'Tetris' worth 800×level points.
Every 10 lines cleared the level goes up and the fall speed increases. Speed keeps ramping until it becomes frantic — survival is the challenge.
NEXT previews the upcoming piece so you can plan. HOLD saves the current piece and swaps it with your held one (once per piece) — great for saving the piece you need.
If a new piece cannot enter the board, the game ends. Your best score is saved on your device for the session.
