Adapted for the fold
- Closed · Outer display
The whole game on the cover
Closed, Terminus plays on the outer display as on any iPhone, with Undo, Hint and Reset under the board.
- Open · Inner display
Board on one page, brief on the other
Open like a book, a station becomes two pages: the board on one, and on the other each line's progress, the rules on the board and your moves. Nothing you touch sits on the crease.
- Book · Partly folded
Brief on top, board on the table
Set down part open like a laptop, the service brief sits on the upper half and the board on the lower half, with Undo, Hint and Reset in a column beside it. The map screen splits the same way.
About Terminus: Transit Map Puzzles
Terminus is a calm logic puzzle about drawing transit lines across a small city grid. On the Duo the board and its service brief sit on facing pages, and folding it into a laptop moves the brief up and leaves the board on the table.
