What is Prism Relay?
Prism Relay is a sliding path puzzle game where you shuffle glowing rail tiles through a single empty gap until one channel of light links the cyan start to the violet goal. Tiles can only slide, never spin, and the channel must also cross every gold light fragment on the board, up to three of them. Each of the 100 levels shows a proven Target, from 1 slide on level 1 to 27 on level 100, and when the route is complete a pearl orb rolls all the way home.
