How to play

Fill entire horizontal rows. Blocks fall automatically; the run ends when the top is blocked. ← → move · ↑ rotate · ↓ soft drop · Space hard drop. Outline shows landing. Clear 10 lines to level up.

Progress and difficulty

Every 10 cleared lines raises the level and shortens the gravity interval. Score rewards 1, 2, 3, or 4 cleared rows with 100, 300, 600, or 1,000 points multiplied by the current level.

Player and save facts

The best score and sound preference stay in this browser. The current board is not saved, and the game has no account or purchase requirement.

Developer note

The next-piece preview and landing outline turn the board into a readable planning problem: choose a legal landing now while keeping future columns open. The same run is playable with visible controls or keyboard commands.

FAQ

How does the round end?: The run ends naturally when the stack blocks the top and no legal landing remains.
How does scoring work?: Clearing 1, 2, 3, or 4 rows awards 100, 300, 600, or 1,000 points, multiplied by the current level.
What is saved?: Best score only; the current board is not saved.
Which controls can I use?: Use the on-screen Left, Rotate, Right, Soft drop, and Hard drop controls; the same commands are also available from the keyboard.
What does the next-piece preview show?: It shows the next piece before it falls, so you can choose a legal landing and keep future columns open.
