Drag each domino onto the heart. Tap a domino to rotate it.
How to play: place all 16 dominoes so every square is covered. Drag a domino onto the board, tap a domino to rotate it, and tap a placed domino to take it back.
Rules: a plain number is the total the pips in that region must add up to. <3 means the total is under 3, >5 means the total is over 5, and ≠ means all pips in that region must be different. Regions with no label have no rule. Check turns on once every domino is placed.
