How to play
Finish Kazunori when every cell, edge, region, and fixed clue satisfies the paired domino room sums completion test. Completion is checked from the entire position, not from a displayed answer or a visual approximation.
- Read the opening of Kazunori by locating every lane, clue, reserve, room, or fixed element named in its rule. Fill each even-sized room to its sum, make equal values form dominoes, and prevent any two-by-two block from using one value throughout. The seeded deal and rules version reproduce that public starting information without exposing a hidden completion.
- Check each proposed action against the current position and this boundary: Fill each even-sized room to its sum, make equal values form dominoes, and prevent any two-by-two block from using one value throughout. Illegal, stale, and post-finish actions are rejected without changing the board.

Strategy tips
- Use each room sum to narrow its equal-number dominoes, then compare adjoining pairs so no two-by-two block can collapse to one repeated value.
- Meeting all sums without pairing every equal value orthogonally leaves isolated copies, while a valid-looking domino may still create a monochrome block.
- During the final few decisions, compare every unresolved obligation with the target: every cell, edge, region, and fixed clue satisfies the paired domino room sums completion test. Keep the option described in the strategy note available until the last forced dependency is settled.
