BridgeBreaker

Choose intermediate stations to close. A closed station blocks every arrow through it. Source and target stay open. All arrows in the map are directed. Stay within the displayed closure budget; reopen a selected station to make room.

Inspect checks actual source-to-target reachability. If a route survives, its full chain is shown. Three different failed inspections end the attempt. Empty and repeated inspections are free. A successful cut banks 100 minus 10 per closure cost above the cheapest cut, 15 per failed inspection, and 10 for a hint. Reveal earns 0.

Connections, fares, rough and closure costs are authored rules for this small board. The game does not query or measure a live semantic graph. Daily results stay fixed. Practice can be replayed. Daily changes at 00:00 UTC. This authored collection repeats 8 daily puzzles and has 4 separate practice puzzles.
