Start playing
- Classic 10×20: timeless single-player with rising speed.
- 10×10 block puzzle: place pieces on a board, clear lines at your pace.
- Number merge: drop tiles and merge values as you make space.
- Sand physics: falling grains reshape pieces and create new challenges.
How to play the classic game
Goal: fit falling Tetriminos to complete horizontal lines. Clearing 4 lines at once is a "Tetris." As you level up, pieces fall faster keep the stack low and stable.
Controls at a glance
- Move: left/right
- Rotate: clockwise/counterclockwise
- Soft drop: faster fall, still controllable
- Hard drop: instant lock on the stack
- Hold piece: save one piece for later
- Next piece: preview the upcoming Tetriminos
Scoring and speed
More lines at once give more points. Modern rules can reward T-Spins and combos. Speed rises by levels, so plan placements early and use hold/next to reduce panic moves.
