Cascade Effect

Controls

Use ← → to move, ↑ to rotate, ↓ to soft drop, SPACE to hard drop instantly. C puts the piece on Hold for later (once per drop). ESC pauses.

Drag left/right to move, tap to rotate, swipe down to drop, swipe up to hold. Prefer buttons? Turn on Control Buttons in Settings.

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. From level 2, some pieces hide one block with a different number — watch the NEXT preview!

Cascade Effect

After a merge, blocks fall down to fill empty spaces. If a falling block makes a new merge, that's a chain — and every further wave raises the multiplier: ×2, ×3, ×4… up to ×8.

Scoring

Each merge scores the new block's value × chain multiplier. Merges inside the piece you just dropped always count ×1 — set up falling blocks to earn the big multipliers!

Plan Ahead

A glowing outline shows which blocks will merge where your piece lands. After touching down you still have a moment to slide or rotate the piece before it locks. Want a harder game? Turn off Merge Preview in Settings.

Game Over

The game ends when blocks stay above the red dashed line at the top. The line starts pulsing when your stack gets close — plan carefully!
