How to play
The board is a scrambled gradient. Move the tiles into their rightful place in the grid. Until the gradient is seamless and all the colors flow perfectly into one another.
Locked tiles are already in their correct positions. Use them to figure out the surrounding colors.
Swap tiles by tapping or dragging any unlocked tile to another
Watch the gradient flow horizontally and vertically through hue, saturation, and brightness
Tips
Start with the locked tiles. Try to find tiles that are just a shade lighter or darker than the locked ones and place them adjacent.
Check the Edges. It is often easiest to solve the outer edges of the grid first to establish the "frame" of the gradient.
Squint Your Eyes. If you’re stuck, try squinting at the screen. This helps your brain ignore the grid lines and see the overall flow of color more clearly.
