falling block puzzle
How to play Tetris
Quick answer: Tetris is a falling block puzzle where complete horizontal lines disappear and award points.
Tetris rules
Blocks fall from the top of the playfield. Move, rotate and drop each piece to build complete lines. The game ends if the stack reaches the top.
Controls
Use arrow keys or WASD for movement, rotate with up, soft drop with down and hard drop with space. Touch buttons are available on mobile.
Scoring and ranking
Tetris rankings use compact scoring: line clears and higher-risk multi-line clears matter without inflating scores too aggressively.
Strategy tips
- Keep the surface as flat as possible.
- Leave a clean well if you are setting up a four-line clear.
- Use hard drop only when the landing position is certain.
