Domino

1. Each domino covers two neighbouring cells; together they cover the whole board.
2. A number means the pips in that region add up to exactly that number.
3. < and > mean the region adds up to less or more than the number.
4. = means every pip value in the region is the same; ≠ means they all differ.
5. Regions without a badge take any values. Place every domino with every rule met to win.

1. Pick and place. Take a domino from the tray, turn it with Rotate or R, then tap a cell: the first half goes there, the second next to it.
2. Read the badges. A badge shows each region’s rule: a sum, < or > a limit, = for equal pips, ≠ for all different. A tick means the rule is met, a warning sign means it is broken.

• Tap a domino in the tray, Rotate to turn it, then tap the cell for its first half
• Tap a laid domino to pick it up again
• Arrow keys move, Enter or Space places, R rotates, Delete removes, Esc puts the domino down
• H for a hint

Easy boards use 4 or 5 dominoes, medium 6 or 7, hard 8 or 9 and expert 10 to 12. Harder boards are larger and carry more exact rules, so fewer arrangements work.
