Pour glowing colours, sort every vial, and watch the lanterns ignite.

Lumen Sort is a calm water sort puzzle with a cosy night-time glow. Tap a vial, pour its top layer into another, and keep going until each vial holds a single pure colour. When a vial is pure and full, its lantern lights with a warm golden flame. Easy to learn, deeply satisfying, and made for winding down.
