How to play
Finish Sukoro when every cell, edge, region, and fixed clue satisfies the orthogonal neighbor count connected numbers completion test. Completion is checked from the entire position, not from a displayed answer or a visual approximation.
- Read the opening of Sukoro by locating every lane, clue, reserve, room, or fixed element named in its rule. Every number equals its count of orthogonally adjacent numbered cells, adjacent values differ, and all numbered cells form one connected group. 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: Every number equals its count of orthogonally adjacent numbered cells, adjacent values differ, and all numbered cells form one connected group. Illegal, stale, and post-finish actions are rejected without changing the board.

Strategy tips
- Use corner and edge degree limits to place small neighbour counts first, while maintaining a path through which all numbered cells can remain connected.
- Matching each local neighbour count can still split the numbered cells into islands, and equal values may not touch even when their counts agree.
- During the final few decisions, compare every unresolved obligation with the target: every cell, edge, region, and fixed clue satisfies the orthogonal neighbor count connected numbers completion test. Keep the option described in the strategy note available until the last forced dependency is settled.
