Terminus: Transit Map Puzzles

Route every line, serve every station, cross only at the interchanges. Forty-six hand-built maps, each with exactly one solution. Quiet, offline, one-thumb.

Terminus is a calm logic puzzle about drawing transit maps.

Each map is a small city grid. Drag every coloured line from terminus to terminus, serve each station exactly once, and pass straight through the diamond interchanges so two lines cross — one across, one down. When the whole network clicks into place, the line opens.

Every map is machine-proven to have exactly one solution. That changes how it feels: you are never guessing, only deducing. If a route seems forced, it is. Follow the logic and the city untangles.

Made for the commute it depicts:

• One-handed, portrait play. The whole game within a thumb's reach. • Fully offline. Quiet optional sounds; the mute switch always wins. • No ads, no accounts, no tracking — ever. • Stars reward pace; hints are there when you want a nudge, not the answer. • Progress travels with you through iCloud. • Line patterns mode tells lines apart by texture as well as colour.

The Ember Line rides free with ten stations, from a gentle 4×4 to a dense 6×7. The Season Ticket opens three further lines — thirty-six more stations up to a severe 7×7 — and every line surveyed in the future. One fare, forever.

Mind the gap between you and your station. It is exactly one line wide.
