How to play Domino Rules

Rules

1. Use every tile once.
2. Each slot has two positions: A1 and A2 are the first and second pips of slot A.
3. Flipping swaps a tile’s two pips. A difference is the distance between values, regardless of their order.
4. Meet every sum, difference, equality and value clue.

How to answer

1. Choose a tile, then tap a board slot to place it. Tap a placed domino to flip it.
2. Choose a used tile to move it. Remove returns the selected tile to the rack; Undo reverses board changes.
3. Nearby clues show which rules are met or still need work. Choose Check dominoes when every slot is filled.

Solving tips

• Tiles with the same total can still behave differently in clues joining two slots. Test their orientation as well as their position.
