Three fresh grids, every day
Squarro is a daily logic puzzle game. Every morning brings one Sparks, one Balance and one Blocks grid, the same three for every player. Each grid has exactly one answer that you can reach by pure logic: no guessing, no lives, no timer pushing you.

Three kinds of logic grid
Pure logic, three ways.
If you enjoy star battle, binary puzzles like takuzu, shikaku rectangle puzzles or just a clean brain teaser with your morning coffee, you will feel at home.
- Star battle style
Sparks
Place one spark in every row, every column and every coloured zone. Sparks never touch, not even at a corner.
- Binary, takuzu style
Balance
Fill the grid with discs and rings. Each row and column holds as many of each, never three alike in a line, and no two lines are the same.
- Shape packing
Blocks
Split the whole grid into rectangles. Each rectangle holds exactly one number, and that number is its size.
New: Challenge
Grids that keep coming, and keep getting harder.
- Endless stages. Each one is a little harder than the last, and every stage is the same puzzle for every player.
- Levels and titles. You earn XP as you play, move up through player levels and get a new title every 10 levels.
- Leaderboards. See how you rank against other players. Joining is optional and you play under a generated name.
- Your progress travels. Sign in and it is saved across your devices.
- Today's Trio stays as it is.
A new trio every day
The same three grids for everyone.
- Today's Trio is ready each morning and identical for every player, so you can compare times with friends.
- The week builds up: gentle 6 × 6 grids on Monday, bigger and harder ones up to 8 × 8 by Saturday.
- Sunday Summit: one big hard grid (9 × 9 or 10 × 10) on top of the trio.
- Streaks with a weekly freeze, so one missed day does not reset your run. Yesterday's unfinished grids wait for you.
- Stats and sharing: a calendar of solved days, best times, and a share card that never shows the grids.
Fair and helpful
Stuck? See the next logical step.
- Every grid is checked by our own solver: one unique solution, reachable by deduction alone.
- Hints that teach: they explain the next step and outline the cells involved, instead of just filling in an answer. Two free hints a day.
- Undo and redo, dots for notes, optional auto-dots in Sparks and gentle highlights when a rule is broken.
- Your pace: pause whenever you like, or hide the timer completely. A short guided first grid gets you started.
The library
Extra grids, day or night.
Want more than three a day? Packs of extra grids: First Sparks, Balance Basics, Block Party and Mixed Easy. Library grids never touch your streak.
- Ten grids open in every pack on your first day, and one more each day after that.
- Light, dark or system theme. Zones use patterns as well as colours, so grids work with colour vision differences.
- Works offline, on the train or on a plane. Progress stays on your device and is backed up anonymously. No account needed.
