Once you’ve collected the required Gem symbols and activated the bonus, you enter a hold-and-win-style feature. Starting with three free spins, any new symbol landings will reset the spin counter so you can keep going — that means the bonus round can extend for a while, creating more opportunity. During this phase the grid may expand (from 15 to 30 positions) if the Jackpot feature is triggered, giving you a larger playing area and more potential for big wins. Meanwhile the Gems you collected above the reels (Double, Ignite, Jackpot) come into play: Double Gems multiply cash prizes, Ignite Gems enhance specific prize values, and Jackpot Gems give access to one of several jackpot levels. That multi-layered bonus structure is really where the excitement comes.
