Clean Slate: Block Puzzle

Drag blocks onto the grid. Fill a row or a column and it clears. Simple to start, and then the crystals arrive.

CRYSTALS IN THE RUBBLE
Every puzzle board starts with stone rubble, and some stones hold a crystal. A crystal only breaks when its row or column clears. Break every crystal to win, using a fixed, known sequence of pieces.

SEE WHAT COMES NEXT
The next three pieces always wait greyed out under your tray, so you plan instead of hoping. Park one piece in the hold slot and bring it back exactly when it fits.

BEAT THE PAR
Every level is generated and played through by a solver before you see it, so every board can be won. Par is the fewest pieces the solver needed. Use fewer pieces for more stars.

FOUR WAYS TO PLAY
Relax: small boards that teach one rule at a time, with spare pieces.
Hard: more crystals deep in the rubble, a few spare pieces.
Expert: no hold slot, more crystals and only one or two spare pieces. Every placement counts.
Classic: the open grid with endless pieces and a score goal per level. Clear lines in a row for combos.

HELP WHEN YOU WANT IT
Undo your last piece (three free per level), ask for a hint that shows the solver's next move, rewind to the last point where you could still win, or blast a 3x3 area when nothing fits.

NO PRESSURE
No timers, no energy, no daily limits. Play fully offline.

ADS AND THE ONE PURCHASE
The game is free. After your first few wins, a short ad may play between levels, at most every third level and never in the middle of a board. Hints, extra undos, rewinds and the 3x3 blast are optional rewarded ads that you choose to watch. The one purchase, Remove Ads, switches off the ads between levels for good; the optional rewarded helps stay available.
