You complete Rail Pool when the completed grid satisfies the room segment inventory constraint set, every fixed clue, and the profile's whole-board completion test. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim.

Complete guide
Rail Pool uses the independently implemented Rail Pool room segment inventory rules profile v1 profile (R554). Rail Pool is a complete deterministic browser game whose distinct rules centre on A cell-covering loop uses only the listed straight-segment lengths in each room and represents every listed length. The independent runtime records this exact room segment inventory rules identity.
Rail Pool opens from a versioned seeded position built for A cell-covering loop uses only the listed straight-segment lengths in each room and represents every listed length. The independent runtime records this exact room segment inventory rules identity. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
Every Rail Pool action is checked against the current board, available material, and this defining restriction: A cell-covering loop uses only the listed straight-segment lengths in each room and represents every listed length. Partial assignments remain legal only while at least one completion still satisfies those constraints. Invalid, stale, or post-terminal actions leave the position unchanged.
You complete Rail Pool when the completed grid satisfies the room segment inventory constraint set, every fixed clue, and the profile's whole-board completion test. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim. Near the end of Rail Pool, recount the remaining obligations needed until the completed grid satisfies the room segment inventory constraint set, every fixed clue, and the profile's whole-board completion test. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.
A practical Rail Pool plan is to preserve several legal continuations around A cell-covering loop uses only the listed straight-segment lengths in each room and represents every listed length. The independent runtime records this exact room segment inventory rules identity. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing. A common Rail Pool error is to ignore the boundary rule that A cell-covering loop uses only the listed straight-segment lengths in each room and represents every listed length. Partial assignments remain legal only while at least one completion still satisfies those constraints. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
Rail Pool has its own runtime and save identity because its rules require A cell-covering loop uses only the listed straight-segment lengths in each room and represents every listed length. The independent runtime records this exact room segment inventory rules identity.
A cell-covering loop uses only the listed straight-segment lengths in each room and represents every listed length. Partial assignments remain legal only while at least one completion still satisfies those constraints.
Rail Pool 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.
