Domino Puzzle: Logic Game

A calm, clever domino puzzle. You get a handful of domino tiles and a shaped board split into coloured regions. Place every tile so that every region keeps its rule. Each puzzle has exactly one answer, and you can always reach it by logic.

THE RULES
- A number: the dots in that region add up to exactly that number
- = : every half in the region shows the same number
- ≠ : no two halves in the region match
- Under 5 : the dots add up to less than 5
- Over 3 : the dots add up to more than 3
- Plain wood squares have no rule

HOW IT PLAYS
- Drag a tile from the tray onto the board
- Tap a tile to turn it
- Drag a tile off the board to take it back
- Undo any move
- Each region's brass token turns green when its rule is met and red if it breaks
