Coil is a sliding puzzle with a twist. Drag any tile toward the blank space to slide it — but every tile you haven't locked rotates 90° with every move. When a tile is in the right position and the right rotation, long-press it to lock it in place. Locked tiles stop rotating and can't be moved. Reconstruct the spiral one locked tile at a time.

Swipe tiles to slide  ·  Hold to lock

Goal: Reassemble the Archimedean spiral.

Swipe any tile toward the blank space to slide it in. Every unlocked tile rotates 90° clockwise on every move.

Hold a tile for half a second to lock it (gold border). Locked tiles are immune to movement and rotation.

A tile is solved when it's in the right position, right rotation, and locked. Lock all 24 to win.
