About this Slot
Gem Forge is a fantasy mining and gems slot from Shift Gaming with an RTP of 96.1%, high volatility and a maximum win of 25,000x. The game uses a 5x5 grid with Cluster Pays mechanics, where winning symbols connect horizontally or vertically.
Multiplier Gems land on the grid with numerical values and act as wilds, substituting for all paying symbols to help form larger clusters. These gems also contribute their multiplier values to wins. After each win, the Cascading Reels feature removes the winning cluster and drops new symbols into the empty spaces, continuing until no further wins are created.
Three Scatters trigger the bonus round, awarding 10 free spins. During this round, the Tumble Multiplier resets at the start of each spin. Four Scatters trigger the Super Bonus, also awarding 10 free spins, but here a Persistent Multiplier never resets between spins and builds whenever Multiplier Gems land. Five Scatters trigger the Epic Bonus, which grants 10 free spins with the Persistent Multiplier carried over from the Super Bonus, plus Sticky Wild Gems that remain on the grid across spins.
The SHIFT BONUS HUNT buy option is available at 5x the bet, offering direct access to the bonus rounds.
