Take the scenic route through a logic puzzle.
The book-like layout suits careful route planning. Start here if your ideal phone game is a small puzzle you can think about at your own pace.
Before you play
The developer describes play on the outer display and a two-page station layout when opened. We have not independently tested session transitions.
What changes on Duo?
According to the developer's App Store description and the version 1.3.1 release notes (October 9, 2026), Terminus plays normally on the outer display. Opened like a book, a station becomes two pages: the board on one, and a service brief with line progress, rules and moves on the other, with the gap between them on the fold. Stood part open like a laptop, the brief sits on the upper half and the board on the lower half, with Undo, Hint and Reset beside it. The map screen splits the same way, and folding or turning mid-station keeps your place.
