About game
Spectrum Lines is a calm color puzzle about order, shades, and smooth transitions.
You see a board of colored tiles. Some tiles are fixed and show the anchor colors, while the rest can be swapped. Your goal is to restore a smooth gradient and turn shuffled shades into a harmonious picture.
There is no timer, no move counter, and no pressure. Play at your own pace, compare colors carefully, and enjoy the result after completing each level.
The difficulty grows gradually: the first levels introduce the simple mechanics, then the boards become larger and the number of anchor points decreases.
How to play
Select a free tile and swap it with another free tile. Tiles marked with dots are fixed: they cannot be moved and show the anchor colors. Arrange the board so the transitions between colors become smooth. After completing a level, press “Next” to continue.
