Domindle
Place dominoes so every colored region's math rule holds.
How to play
- Fill the board with the domino bones in the tray.
- Each colored region carries a constraint — sum equals / less / greater, all-equal, all-different, even, odd, and more.
- Every region's rule must hold once the board is full.
Controls
- Tap a domino to pick it up, tap a cell to place; tap again to rotate.
Techniques
Most constrained first
Regions with the tightest rule (an exact sum in two cells, all-equal in three) admit the fewest bones — solve them before the open areas.
Count the pips
The tray is finite. If a region needs a 6 and only one unplaced bone carries a 6, its other half is decided too.
Watch the amber
Amber means a region can no longer be satisfied — some placed bone elsewhere is wrong. Undo early rather than building on a broken region.
Example
[ 2 | 3 ] sum = 5 ✓
Place dominoes so each region’s rule holds — here 2 + 3 = 5.
Tip · Solve the most-constrained regions first. Red = full-but-wrong; amber = no longer possible.
