Complete guide
Icebarn uses the independently implemented Icebarn entrance exit arrow ice path rules v1 profile (R649). In Icebarn, the position revolves around this rule: A single path enters and exits the border once, obeys directional arrows, and travels straight through ice even when two independent strands cross there.
Icebarn starts with its fixed information already marked and its editable spaces left for the player. A single path enters and exits the border once, obeys directional arrows, and travels straight through ice even when two independent strands cross there. Restart reconstructs the same opening from the stored game ID, rules version, and seed.
A move in Icebarn is accepted only while it preserves every already-visible requirement. A single path enters and exits the border once, obeys directional arrows, and travels straight through ice even when two independent strands cross there. Failed validation leaves the move count, history, and board exactly as they were.
Icebarn is complete once every cell, edge, region, and fixed clue satisfies the entrance exit arrow ice path completion test. The terminal check examines every relevant pile, cell, edge, room, and clue before awarding the result. At the end of Icebarn, 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 entrance exit arrow ice path completion test.
Build outward from the entrance and exit, carrying direction through arrow cells and straight across ice while keeping crossing strands logically separate. Joining the two strands at an ice crossing or reversing an arrow changes path connectivity even though the drawn lines may still appear continuous.
Build outward from the entrance and exit, carrying direction through arrow cells and straight across ice while keeping crossing strands logically separate. This matters specifically because a single path enters and exits the border once, obeys directional arrows, and travels straight through ice even when two independent strands cross there.
Joining the two strands at an ice crossing or reversing an arrow changes path connectivity even though the drawn lines may still appear continuous. Recheck the legal boundary before choosing a replacement move.
The winning condition for Icebarn is precise: every cell, edge, region, and fixed clue satisfies the entrance exit arrow ice path 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.
