Noktura: Rotate Ring Puzzle

Noktura is a calm ring puzzle under the night sky. Rotate rings in the right order, slip them out of their clasps and untangle the knot until a new star lights up. Easy to learn, hard to master, and there is no time limit: just you, the rings and a quiet moment to think. Every level is a knot of linked rings. Each ring has a gap, and clasps tie it to its neighbors. Turn a ring with your finger: when its gap reaches a clasp, that clasp lets go. But a ring that holds another ring is locked, a ring held by two clasps cannot slip both at once, and if you turn too far a clasp catches the ring again. Plan ahead, find the order and unlock every piece. It is a true logic puzzle, not a race. Each solved ring puzzle lights one star, ten stars join into a constellation, and your sky slowly fills as you play. The first knots are quick to read; later boards ask you to study the whole knot, spot the one ring that can move and think several turns ahead. Short break or long night, there is always one more knot waiting.
