Shade Sort, free to play

A square of colour tiles that blend smoothly from the four corners has been mixed up. Swap tiles until the colours flow again. A new one every day.

How to play

Look at the corners
The four corner tiles stay where they are. Every other tile belongs somewhere on the smooth blend between them.
Swap two tiles
Tap one tile, then another, and they trade places. A dot on a tile means it is in the right place.
Make it flow
When every tile is home, the colours run smoothly from corner to corner and you have solved it. There is a par for the fewest swaps.
