About the picture
On a windless night the lake becomes a second sky: the green band of the aurora, its violet upper edge and the scattered stars all appear twice, split by a thin line of spruce and pine. A few smooth boulders break the surface in the foreground — the only places where the reflection is interrupted.
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 aurora band, the spruce silhouettes, the boulders in the water.
Then fill the picture area by area. The slow part: the night sky, the still water. Use the preview button to compare tiles from these areas with the full picture.
