Rotate and drop falling blocks to clear complete lines before the stack reaches the top. A classic line-clearing puzzle, playable with keyboard or on-screen buttons.
Rules
A new block falls from the top every drop tick. Move it left/right, rotate it, or drop it faster with the arrow keys (or the on-screen ◀ ↻ ▼ ▶ buttons).
Press Space (or hold ▼) to hard-drop a block straight down.
Complete a full horizontal line to clear it and score — clearing multiple lines at once scores far more.
The game ends the moment a new block has nowhere to appear. Press P (or the ⏸ button) to pause at any time.
Tips
Keep the board flat and low! Never leave isolated single-cell gaps — they’re nearly impossible to clear.
