Complete guide
Onsen Meguri uses the independently implemented Onsen Meguri numbered room loop length rules v1 profile (R652). Onsen Meguri is defined by one exact interaction: A single loop crosses every room, and each room clue gives the number of loop cells used within that room.
Read the opening of Onsen Meguri by locating every lane, clue, reserve, room, or fixed element named in its rule. A single loop crosses every room, and each room clue gives the number of loop cells used within that room. 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: A single loop crosses every room, and each room clue gives the number of loop cells used within that room. Illegal, stale, and post-finish actions are rejected without changing the board.
Finish Onsen Meguri when every cell, edge, region, and fixed clue satisfies the numbered room loop length 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 numbered room loop length completion test. Keep the option described in the strategy note available until the last forced dependency is settled.
Allocate each room's exact loop length before fixing its entrance and exit edges, then connect the room passages into one global cycle. Matching a room count with two disconnected visits violates the single-entry/single-exit structure even if the total number of used cells is correct.
Allocate each room's exact loop length before fixing its entrance and exit edges, then connect the room passages into one global cycle. This matters specifically because a single loop crosses every room, and each room clue gives the number of loop cells used within that room.
Matching a room count with two disconnected visits violates the single-entry/single-exit structure even if the total number of used cells is correct. Recheck the legal boundary before choosing a replacement move.
Onsen Meguri is complete once every cell, edge, region, and fixed clue satisfies the numbered room loop length 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.
