About game
Sorting colorful tiles by their exact shade feels surprisingly satisfying when you just want to unwind for a few minutes. Spectrum Lines focuses on arranging shuffled pieces until every transition flows perfectly from one side of the board to the other. You select two tiles to swap their positions, constantly eyeing the subtle differences in tone to find the right spot. Fixed anchor points act as your guideposts, forcing you to think ahead as the board expands. This logic puzzle removes all timers and move limits so you can focus entirely on the visual harmony of the colors. Complexity ramps up slowly as you tackle wider grids with fewer fixed markers to rely on. Designing a flawless gradient gives you a real sense of accomplishment without any frustration. You can play Spectrum Lines right here in your browser without needing to download a single file.
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.
