Wizard of Gems is a Play'n GO video slot released in December 2015. The game uses five reels and 20 fixed paylines, with a fantasy theme built around gemstones, spell books, stars, and other wizard symbols. Winning combinations can appear on any of the active lines.
The slot uses a cascading mechanic: winning symbols disappear and are replaced by new ones falling into place, which can create additional wins from a single spin. A progressive multiplier rises from 2 to 3 and then to 5 for subsequent cascades. The wild spell book substitutes for all standard symbols except the star.
Three star symbols trigger the free spins feature, awarding 10 spins at a time. During this bonus round, each spin can add up to nine wild spell books, and another set of three stars can add 10 more spins, with a maximum of 50 free spins. The demo version lets players play for free and practice before playing for real money.
