Flickmoor

Flickmoor is a lights-out puzzle with paper lanterns on a moor at dusk. Tap a lantern and it flips together with its neighbours; the goal is to light every one. Forty puzzles in four parts of the moor bring in one idea at a time: plain crosses, standing stones that leave gaps, diamond lanterns that flip the corners instead of the sides, and three-step lanterns that go from dark to amber to silver. Every puzzle has a par, the fewest taps that solve it, and up to three stars; undo, restart and a hint are always there. A new lantern of the day waits every day. It plays in the browser with a keyboard, mouse or touch, in English or Bulgarian.
