Photo maze questions
How does a photo become a maze?
The centre of the photo is resized to 13 × 13 squares. Squares lighter than the average become light paths; the others become dark paths. Flipping changes which colour you can enter.
What does minimum flips mean?
It is the fewest colour changes needed to reach the goal on the current map. You can take extra steps to find a route with fewer flips.
Can I play without choosing a photo?
Yes. A generated sample is ready immediately. Another sample gives you a different map with the same rule.
