Cojun

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.

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.
  • 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.

Strategy tips

  • Fill each room as a complete one-to-size set, then use vertical same-room ordering and cross-room adjacency differences to orient the remaining values.
  • Applying the downward increase across a room border invents a constraint, while ignoring it within one room reverses otherwise valid candidates.
  • At the end of Cojun, recount the remaining destinations, marks, or connections before committing the narrowest move. The finish is accepted only when every cell, edge, region, and fixed clue satisfies the ordered room latin adjacency completion test.

Complete guide

Rules, scoring, and strategy

Cojun uses the independently implemented Cojun ordered room latin adjacency rules v1 profile (R665). In Cojun, the position revolves around this rule: Each room contains one through its size, orthogonal neighbours differ, and vertically consecutive cells in the same room increase downward.

Setup and opening position

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.

Legal moves and game flow

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.

Winning and terminal positions

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. At the end of Cojun, recount the remaining destinations, marks, or connections before committing the narrowest move. The finish is accepted only when every cell, edge, region, and fixed clue satisfies the ordered room latin adjacency completion test.

Practical strategy

Fill each room as a complete one-to-size set, then use vertical same-room ordering and cross-room adjacency differences to orient the remaining values. Applying the downward increase across a room border invents a constraint, while ignoring it within one room reverses otherwise valid candidates.

Questions players ask

When should players account for downward ordering inside each room in Cojun?

Fill each room as a complete one-to-size set, then use vertical same-room ordering and cross-room adjacency differences to orient the remaining values. This matters specifically because each room contains one through its size, orthogonal neighbours differ, and vertically consecutive cells in the same room increase downward.

What false assumption most often blocks Cojun?

Applying the downward increase across a room border invents a constraint, while ignoring it within one room reverses otherwise valid candidates. Recheck the legal boundary before choosing a replacement move.

How does Cojun confirm the final position?

The winning condition for Cojun is precise: every cell, edge, region, and fixed clue satisfies the ordered room latin adjacency completion test. No hidden solution values are printed to justify the result; the rules engine validates the submitted position. Undo and redo expose alternative branches without revealing an authored answer.
