How to play
Success in Bonsan requires that every cell, edge, region, and fixed clue satisfies the clue distance straight movement completion test. The game declares completion only after all interacting restrictions agree at the same time.
- The Bonsan opening separates permanent constraints from player-controlled positions. Move each clue circle exactly its stated distance along one straight, nonoverlapping route until it reaches a target cell. Its versioned seed recreates those same constraints locally while keeping unrevealed decisions out of the guide and board labels.
- Bonsan treats the printed or dealt restrictions as hard constraints, not suggestions. Move each clue circle exactly its stated distance along one straight, nonoverlapping route until it reaches a target cell. A move that contradicts the current state has no effect, including after the game has ended.

Strategy tips
- Draw each clue's straight route at its exact distance and reserve target cells for the circles with the fewest alternatives before extending flexible routes.
- Measuring only the destination displacement while allowing routes to overlap ignores the occupied cells between start and target.
- Close Bonsan 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 clue distance straight movement completion test.
