Domino District

About this game

Domino District is a daily logic game where you cover a city grid with dominoes, using each number pair exactly once, with a new date-seeded district every day plus free-run districts. It is one of the most satisfying puzzle games for players who like quiet deduction: every puzzle is checked for a single unique solution before you play it, and confirmed districts light up house by house on the city map.

How to play

1. Tap a plot, then tap a neighboring plot to lay a domino over both plots.
2. Cover every plot. No number pair may repeat anywhere on the board.
3. Tap a laid domino to lift it, or use Undo to take back your last move.
4. Use Check to confirm districts and light their houses, or Hint to lay one correct domino.
5. Finish the board with every pair used exactly once to light the whole district.

Tips

• Start from plots with only one possible neighbor pairing and work outward from there.
• If a pair is refused as already laid, that pairing is ruled out, which is itself a useful clue.
• Check early in Daily mode: confirmed districts lock in, so the rest of the board gets easier, not harder.
