Rings circle the faces. Each of the 12 faces wears 4 rings: ring 1 is its center and the ten tiles round it, ring 2 its rim, and rings 3 and 4 the first and second rows of tiles across its five neighbors. A turn spins a ring a fifth of the way round.
Turn a ring by swiping along it on the dial, with the ↺ ↻ buttons, or by dragging a tile on the 3D puzzle. Most tiles ride two or three rings, and the direction you drag picks which.
Two dials. The ring dial draws the chosen face's rings as circles, ring 1 in the middle and ring 4 round the outside, with the edges between its neighbors marked across rings 3 and 4. The button beside the face picker swaps it for the face with its five neighbors unfolded flat around it.
Pick a face with ‹ ›, a neighbor's badge on the dial's rim (or, unfolded, a tap on the neighbor itself), or a tap on the puzzle. Cap turns a ring along with everything inside it: Cap on ring 3 turns a whole face, the way a real Gigaminx does.
Look around by dragging the space around the puzzle (or right-drag, or two fingers). Scroll or pinch to zoom; double-tap to reset.

The solid is the regular dodecahedron, and its faces carry the Gigaminx pattern: two cuts beside every edge, so each edge has five tiles along it (corner, wing, middle, wing, corner) and each face 31. Every cut is the trace of a plane parallel to a neighboring face, so every ring turns as a true rotation.
