How to play
Success in Uso Tatami requires that every cell, edge, region, and fixed clue satisfies the liar clue tatami partition completion test. The game declares completion only after all interacting restrictions agree at the same time.
- The Uso Tatami opening separates permanent constraints from player-controlled positions. Partition the board into rectangles without four-way boundary meetings; every room has one area clue and exactly one clue on the board is false. Its versioned seed recreates those same constraints locally while keeping unrevealed decisions out of the guide and board labels.
- Uso Tatami treats the printed or dealt restrictions as hard constraints, not suggestions. Partition the board into rectangles without four-way boundary meetings; every room has one area clue and exactly one clue on the board is false. A move that contradicts the current state has no effect, including after the game has ended.

Strategy tips
- Mark candidate rectangle areas for every clue, reserve exactly one contradiction for the liar, and reject any layout where four room corners meet.
- Treating several inconvenient clues as false avoids local conflicts but violates the single-liar rule; exactly one area statement must fail.
- Close Uso Tatami by auditing the boundary cases first and the obvious placements second. The position is not done until every cell, edge, region, and fixed clue satisfies the liar clue tatami partition completion test.
