About the picture
The reindeer appear only as shapes — legs, backs and the branching outline of antlers — against the snow and the glowing sky. Behind them a line of low birch scrub marks the horizon, and the aurora swirls in green and purple over the whole herd.
Computer-generated scene; it does not show a specific real place.
How to approach this swap puzzle
A tile that lands in its correct place locks and gets an outline, so every good swap is permanent. Start with tiles that are easy to place by eye: the reindeer, the antlers, the aurora band.
Then fill the picture area by area. The slow part: the open snow, the night sky. Use the preview button to compare tiles from these areas with the full picture.

Large areas of nearly one tone — a slow, absorbing puzzle. A smaller size makes a good warm-up. Demanding →
