Complete guide
Nikoji uses the independently implemented Nikoji paired clue congruent regions rules v1 profile (R656). Nikoji is defined by one exact interaction: Divide the grid into regions containing matching clue pairs; equally labelled regions must be congruent up to allowed translation, rotation, or reflection.
Read the opening of Nikoji by locating every lane, clue, reserve, room, or fixed element named in its rule. Divide the grid into regions containing matching clue pairs; equally labelled regions must be congruent up to allowed translation, rotation, or reflection. 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: Divide the grid into regions containing matching clue pairs; equally labelled regions must be congruent up to allowed translation, rotation, or reflection. Illegal, stale, and post-finish actions are rejected without changing the board.
Finish Nikoji when every cell, edge, region, and fixed clue satisfies the paired clue congruent regions completion test. Completion is checked from the entire position, not from a displayed answer or a visual approximation. During the final few decisions, compare every unresolved obligation with the target: every cell, edge, region, and fixed clue satisfies the paired clue congruent regions completion test. Keep the option described in the strategy note available until the last forced dependency is settled.
Pair identical clues, sketch one candidate region shape, and test whether its mate can receive a congruent copy without stealing a third clue or cell. Matching region areas alone is insufficient; the paired regions must have congruent geometry under the transformations allowed by the rule.
Pair identical clues, sketch one candidate region shape, and test whether its mate can receive a congruent copy without stealing a third clue or cell. This matters specifically because divide the grid into regions containing matching clue pairs; equally labelled regions must be congruent up to allowed translation, rotation, or reflection.
Matching region areas alone is insufficient; the paired regions must have congruent geometry under the transformations allowed by the rule. Recheck the legal boundary before choosing a replacement move.
Nikoji is complete once every cell, edge, region, and fixed clue satisfies the paired clue congruent regions completion test. The terminal check examines every relevant pile, cell, edge, room, and clue before awarding the result. Undo and redo expose alternative branches without revealing an authored answer.
