Remove one block
Tap Hammer, then tap any block on the board to remove it. Best moment: one stubborn cell stands between you and a line clear or a free 3×3. Mistake: smashing a block in an area you were about to clear anyway.
Block puzzle boosters & power-ups
The right tool, at the right moment.
Boosters are the four tools under the board: Hammer, Rotate, Shuffle and Undo. You keep a stock of each and use them in any mode. Big clears also earn two power-ups, the Bomb and Lightning. Here is what each one does and when it pays off.
The four boosters
Hammer Shuffle Get three fresh pieces
Trade your current tray for three new pieces. Best moment: nothing in the tray fits the board. Mistake: shuffling a tray that fits, just hoping for better pieces.
Undo Take back your last move
Your last placement goes back to the tray. Best moment: you dropped a piece one cell off and blocked a line. Unlimited in Zen.
Using the Hammer
When the Hammer is active, the board dims and the Hammer button lights up. Tap the block you want gone and it is smashed off the board.
The best target is usually the single block that keeps a row or column from completing, or the one cell that stops a 3×3 space from opening.
Power-ups: Bomb and Lightning
Power-ups are not bought; you earn them during a run by clearing several lines with one piece. They appear next to your boosters.
2 lines Bomb
Earned by clearing two lines with one piece. It clears a 3×3 area of the board: perfect for a crowded corner.
3+ lines Lightning
Earned by clearing three or more lines with one piece. It clears two random rows and two random columns.
How to get more boosters
Boosters are shared across all modes. You collect them as rewards while you play, and you can buy more in the Shop with coins you earn from levels, the Daily Puzzle and other runs. Optional ads can add extra coins if you choose to watch them.
The game is fully playable without boosters. Think of them as a safety net for the hardest boards and the boss levels.

Can I play without boosters?
