Analyze the Chaos: Each puzzle starts with a scrambled grid of vibrant color tiles. 2. Watch the Anchors: Pinned tiles marked with a subtle central dot are "Anchors." They are locked in place to act as your guides. 3. Sort the Spectrum: Tap any two unlocked tiles to swap them. 4. Restore Harmony: Arrange the board so the colors shift seamlessly from one corner to the next. When the canvas blends perfectly, harmony is restored! - Game Features * Infinite Level Generation: Thanks to our programmatic spectrum generator, you can climb the ranks through endless, mathematically unique color gradients.
