Dominoes

1. Place every domino so each one covers two neighbouring cells.
2. Each coloured region follows its rule: a number is the total pips; < or > means less or more than it.
3. = means every pip count in the region matches; ≠ means they all differ.
4. Plain cells have no rule. Every board has one answer.

Tap a domino to pick it up and again to turn it, then tap where its first half goes. Tap a placed domino to lift it back.
