Coral Net

Coral Net is a calm, one-thumb untangle puzzle. Each net is a net of glowing pearls joined by luminous strands, dropped onto the board in a scramble so the strands cross over one another in a knot. Your task is quiet and simple: slide the pearls until nothing overlaps.

The whole game is one touch. Press and drag any pearl with your thumb and every strand tied to it stretches and follows, live, as you move it around the board. Any strand that still crosses another glows red, so the tangle shows you exactly where the trouble is. Ease the pearls apart, open the knots, and watch the red fade to calm.

A live counter at the top shows how many crossings remain; bring it down to zero and the whole net snaps into a clean, crossing-free shape. There is no timer, no score to race and no way to fail — Coral Net is built for slow, satisfying thinking, not pressure. Tangled beyond reading? Tap RESET at any time to drop the pearls back to their opening scramble and begin the untangle fresh.

Every net is solvable by construction. When each board is built it is laid out as a planar graph first and only then scrambled, so a clean, crossing-free arrangement is always there to be found — the only question is whether you can find it. Ten nets grow from a handful of pearls to dense, knotty webs of a dozen or more, each with more strands to unpick than the last. Progress is saved on your device as you solve them, one net at a time.
