# Wraparound

Topology · 30 levels

Walk off one edge, come back on the other. Upside down?

## How to play

- Steer with the arrows or swipe. Walk off an edge with a coloured bar and you come back on the edge of the same colour.
- Arrows on the bars show the gluing: same direction means straight across; opposite arrows mean you come back upside down (the row flips).
- Collect every ⭐ and reach the portal within the step limit. Early levels allow spare steps.

The faded strips beyond each edge show what is waiting on the other side. On a Möbius strip, the top row on the right is the bottom row on the left.
