Semantic Subway Tiles

Build a line. Make every link and service fit.

All games

How to play

Add tiles from the bank, move them Earlier or Later, or Return a tile. You may leave spare tiles unused. Every adjacent pair needs a directed arrow in the map, and your line must visit both required services. Editing is free.

A successful inspection banks points: 100 minus 3 per fare above the cheapest valid line, 15 per failed inspection, and 10 for a hint. Three different failed inspections end the attempt. Empty and repeated inspections are free. Reveal earns 0.

Connections, fares and required services 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.
