How the Game Plays

The Gem Machine, developed by Light & Wonder (under the Bally brand), completely reimagines traditional slot mechanics. Set inside a steampunk-inspired mechanical laboratory, the 5x3 grid doesn't use standard paylines or winning combinations. Instead, the game features blank spaces where only specific symbols—Gems or Jackpots—can land to award prizes. You have the unique ability to activate between one and five reels per spin, with the theoretical return to player (RTP) increasing as more reels are put into play. When a colored gem lands on an active reel, it awards an instant cash prize based on the value displayed on the symbol.

Five-Tier Jackpots Explained

The Gem Machine features five fixed jackpots: Mini, Minor, Major, Mega, and Grand. These are won by landing the corresponding Jackpot Gem on its designated reel. For instance, the Grand Jackpot symbol only appears on the fifth reel and offers the game's top prize of 5,000x the stake per reel. Since you can choose which reels to activate, you essentially decide which jackpots are available to be won during any given spin.
