How to play
You complete Country Road when the completed grid satisfies the single room visits 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.
- Country Road opens from a versioned seeded position built for A single loop visits every country once; clues count used cells and cross-country neighbours cannot both be unused. The independent runtime records this exact single room visits rules identity. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
- Every Country Road action is checked against the current board, available material, and this defining restriction: A single loop visits every country once; clues count used cells and cross-country neighbours cannot both be unused. Partial assignments remain legal only while at least one completion still satisfies those constraints. Invalid, stale, or post-terminal actions leave the position unchanged.

Strategy tips
- A practical Country Road plan is to preserve several legal continuations around A single loop visits every country once; clues count used cells and cross-country neighbours cannot both be unused. The independent runtime records this exact single room visits rules identity. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
- A common Country Road error is to ignore the boundary rule that A single loop visits every country once; clues count used cells and cross-country neighbours cannot both be unused. 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.
- Near the end of Country Road, recount the remaining obligations needed until the completed grid satisfies the single room visits 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.
