Complete guide
Shisen-Sho uses the independently implemented Shisen-Sho PySolFC 3.6.1 fixed rules v1 profile (R1007). Shisen-Sho is a complete deterministic browser game whose distinct rules centre on an eighteen-by-eight tile-removal board where equal tiles connect through vacant cells or the empty perimeter with no more than two turns.
Shisen-Sho opens from a versioned seeded position built for an eighteen-by-eight tile-removal board where equal tiles connect through vacant cells or the empty perimeter with no more than two turns. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
Every Shisen-Sho action is checked against the current board, available material, and this defining restriction: a pair is legal only when a zero-, one-, or two-turn orthogonal path exists; after removal, each affected column compacts downward and the changed geometry governs the next path search. Invalid, stale, or post-terminal actions leave the position unchanged.
You complete Shisen-Sho when all seventy-two matching pairs have been removed without using a shuffle. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim. Near the end of Shisen-Sho, recount the remaining obligations needed until all seventy-two matching pairs have been removed without using a shuffle. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.
A practical Shisen-Sho plan is to preserve several legal continuations around an eighteen-by-eight tile-removal board where equal tiles connect through vacant cells or the empty perimeter with no more than two turns. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing. A common Shisen-Sho error is to ignore the boundary rule that a pair is legal only when a zero-, one-, or two-turn orthogonal path exists; after removal, each affected column compacts downward and the changed geometry governs the next path search. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
Shisen-Sho has its own runtime and save identity because its rules require an eighteen-by-eight tile-removal board where equal tiles connect through vacant cells or the empty perimeter with no more than two turns.

Shisen-Sho stores its game ID, rules version, and seeded deal identity. Those values recreate the same opening locally without promising that the position is forced or winnable.
