About 77rrLock
Color tuning puzzle is a compact offline puzzle game about matching a hidden target color by rotating layered rings.
Each puzzle begins with a short loading screen, then places you in a dark, high-contrast board where every ring can be rotated step by step. The center preview updates as you tune the rings, so you can compare the current mix against the target swatch and track your accuracy.
The game includes multiple difficulty levels, move limits, reset actions, and a fresh puzzle flow for continued play. A local clear history records recent wins, including level, difficulty, moves used, and accuracy, so you can review your progress on the device without an account or online sync.
The experience is designed for quick sessions and careful observation. Rotate a ring, check the mix, and keep refining until the target color is reached.
