About this game
CrackTheGrid is a number puzzle where logic — not speed — wins.
Each grid is split into colored regions. Every row, column, and region has a target sum. Tap cells to mark them as "keep" or "clear" until every row, column, and region matches its target exactly. Get it wrong and you'll lose a heart — get it right and watch completed regions and rows fade away as you close in on the full grid.
Around 5,000 handcrafted-style puzzles across easy, medium, and hard difficulty
8×8 and 9×9 grids, unlocking gradually as you progress
No timer, no countdown, no pressure — solve at your own pace
Stuck? Use a hint, or skip ahead to the next puzzle any time
No login, no account, no personal information required
Free to play
