How to play
Cojun is complete once every cell, edge, region, and fixed clue satisfies the ordered room latin adjacency completion test. The terminal check examines every relevant pile, cell, edge, room, and clue before awarding the result.
- Cojun starts with its fixed information already marked and its editable spaces left for the player. Each room contains one through its size, orthogonal neighbours differ, and vertically consecutive cells in the same room increase downward. Restart reconstructs the same opening from the stored game ID, rules version, and seed.
- A move in Cojun is accepted only while it preserves every already-visible requirement. Each room contains one through its size, orthogonal neighbours differ, and vertically consecutive cells in the same room increase downward. Failed validation leaves the move count, history, and board exactly as they were.
