Pinco

Pinco
Pinco is a concentric-ring alignment puzzle. Every level is a small mechanical dial: several rings nested around a fixed centre hub, each ring carrying coloured marbles seated in its own notches. Tap any ring to turn it exactly one notch - each ring moves independently, and finding the rotation that works for all of them at once is the whole game.

A marble can only roll inward to the hub when its own ring's notch, and every ring between it and the centre, all line up at the very same angle, opening a clear channel in - and it must arrive at a hub socket of its matching colour. Watch the live HOME counter under the dial: the level is won the instant every marble is aligned at once.

Twenty dials climb steadily: more rings, more notches around the circle, and more colours in play, so later boards ask you to reason about several simultaneous alignments instead of one. Every single layout is generated from a fixed seed and proven solvable before it ever reaches a player - there are no dead ends, only cleaner or messier solutions.

There is no way to lose a dial. Take a wrong turn and Reset snaps you straight back to the start with no penalty beyond a few extra spins, so the only thing being tested is your eye for rotation. Stars reward efficient, fast solves; coins earned along the way are yours to keep. No pay-to-win, no timers pressuring a guess - just the quiet satisfaction of watching every ring click into place.
