10 rooms on a side
Ten by ten still fits a phone. Use it when eight rooms feel automatic.
Branches run a little longer than Easy, but you can still see the exit corner from the start. Good warm-up before the daily twelve, or a fog board that does not need zoom.
The number is rooms, not pixels. Walls sit between rooms, so the drawing is 21 tiles across. Start is top-left; exit is bottom-right. Same seed, size, and mode rebuild the same corridors.
How to walk it
Arrows and swipe take a whole corridor and stop at the next fork. Yellow marks where you moved — not a solved path. Hint draws one solid arrow; Peek flashes the shortest route. Either leaves that run off local Marks.
Also: all room counts, make desk, print this size, right-hand rule.
