Prism of Gems is a five-reel video slot from Play'n GO with dynamic payways and up to 3,087 ways to win. The game uses cascading reels, so winning symbols are removed before new ones drop into place, creating the chance of additional wins from a single spin. The layout also includes a horizontal Multiplier Reel, which links to the main reels during play.
The Wild symbol appears only on the Multiplier Reel and can substitute for all symbols except Scatter. As cascades continue, multipliers on the reel can increase by one step at a time, up to x7, with a maximum combined multiplier of x343. Reels 2, 3 and 4 can also expand or split depending on matching symbols, which changes the number of active payways from spin to spin.
Three, four or five Scatter symbols trigger 10, 15 or 20 free spins, and each Scatter in the bonus round adds two more. Multipliers carry into the free spins feature and continue to build until it ends. The demo version is available to play for free, which lets users practice before playing for real money.
