You complete Light and Shadow when the completed grid satisfies the signed monochrome regions 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
Light and Shadow uses the independently implemented Light and Shadow signed monochrome regions rules profile v1 profile (R547). Light and Shadow is a complete deterministic browser game whose distinct rules centre on Every monochrome component contains exactly one fixed-colour clue equal to its area. The independent runtime records this exact signed monochrome regions rules identity.
Light and Shadow opens from a versioned seeded position built for Every monochrome component contains exactly one fixed-colour clue equal to its area. The independent runtime records this exact signed monochrome regions rules identity. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
Every Light and Shadow action is checked against the current board, available material, and this defining restriction: Every monochrome component contains exactly one fixed-colour clue equal to its area. 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 Light and Shadow when the completed grid satisfies the signed monochrome regions 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 Light and Shadow, recount the remaining obligations needed until the completed grid satisfies the signed monochrome regions 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 Light and Shadow plan is to preserve several legal continuations around Every monochrome component contains exactly one fixed-colour clue equal to its area. The independent runtime records this exact signed monochrome regions rules identity. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing. A common Light and Shadow error is to ignore the boundary rule that Every monochrome component contains exactly one fixed-colour clue equal to its area. 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.
Light and Shadow has its own runtime and save identity because its rules require Every monochrome component contains exactly one fixed-colour clue equal to its area. The independent runtime records this exact signed monochrome regions rules identity.
Every monochrome component contains exactly one fixed-colour clue equal to its area. Partial assignments remain legal only while at least one completion still satisfies those constraints.
Light and Shadow 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.
