Cascade Effect

🎮

Controls

Use ← → to move, ↑ to rotate, ↓ to soft drop, SPACE to hard drop instantly.

Use the on-screen buttons below the board to move, rotate and drop pieces.

🔢

Merge Numbers

When two blocks with the same number touch — vertically or horizontally — they merge into one block with double the value. 2+2=4, 4+4=8, and so on.

⚡

Cascade Effect

After a merge, blocks fall down to fill empty spaces. This can trigger chain reactions — one merge leads to another, multiplying your score!

📈

Scoring

You score the value of each merged block. Chain multiple merges in one drop to multiply your score!

Game Over

The game ends when a new piece cannot be placed — the board is too full. Plan carefully!
