Wrap mode
Edges connect to the opposite side · every size · separate best times
Turn on Wrap and the board becomes a torus: a wire that leaves the right edge comes back in on the left, top connects to bottom. The dashed outline around the board tells you it is on.
Why it is harder
- On a plain board an edge tile has a dead side, which fixes it almost for free. With Wrap every tile has four live neighbours.
- The circuit can run around the board, so a branch you think is a dead end may feed the far side.
- There are still no loops and still one power source; counting openings is the way in.
How it works in the game
- Wrap is a mode of its own: best times are kept separately for each size with Wrap, and History marks wrap boards.
- Share links and cards carry the flag, so a friend opens the same wrapped scramble.
- The daily board never wraps; everyone solves the same plain board (7×7, or 9×9 at weekends).
Pick a size: Easy, Medium, Hard or Expert, all with Wrap on.
