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.
How can I avoid holes when stacking falling blocks?: Before dropping, look for empty cells that the piece would cover. A hard drop cannot pass through settled blocks to fill a hole beneath them. Keep the surface low and leave useful gaps open from above. The landing outline shows a legal position, not necessarily a good one; when the stack is high, clearing a single row can be safer than waiting for a four-row clear.
Why does my score rise without clearing a row?: Each successful manual soft-drop step adds 1 point; a hard drop adds 2 points for each row the piece travels and locks it immediately. For example, a hard drop through 5 rows adds 10 points before any line-clear reward. Automatic falling, moving sideways and rotating add no points by themselves. Check the landing outline before committing: a locked piece cannot be moved again.
