How to play Pairs
- Tap the gap between two orthogonally adjacent numbers to make a domino. You can also tap the two cells in turn.
- Every cell must belong to exactly one domino.
- Each unordered pair appears exactly once, from 0-0 through the largest-number pair.
- Tap either half of an existing domino to remove it. The puzzle completes when the whole grid is correctly paired.
Your first useful move
List the possible positions of a pair that appears only once in the grid. Once that domino is placed, remove overlapping possibilities and look for the next forced pair.
