Features You Will Find on Gem Heat Online Slots
Gem Heat Online Slots may have a classic aesthetic, but it moves with a fluency that you won’t find on classic slots and there is also a fire theme that brings some depth and warmth to the reels. There are some high-paying symbols across the board and there are some features that you can trigger and even unlock yourself:
- Hi Roller: Players can trigger “Hi Roller” mode by selecting it from the bottom-right, next to the “spin” This activates 5 spins with added wilds and upgrades. There is a 10x Diamond wild that can land on the third reel during this mode and there is also a 20x Diamond wild that can land on the second, third and fourth reels.
- Free Games: The main bonus feature on Gem Heat Online Slots is triggered when the Gem Heat fire symbols appear on the first, third and fifth reels. This triggers a total of 7 free spins, with a Diamond wild symbol locked in the centre of the reels throughout. The wild symbol can also upgrade all three of the “7” symbols, potentially stacking-up those big wins.
- Autoplay: This feature can be triggered by pressing the “Autoplay” button and choosing a number of spins. As many as 99 spins can be set, at which point the reels just keep on spinning without any input from the player.
- Turbo: This mode increases the speed without altering the player’s chance of winning. The reels spin quickly and a single spin takes less than a second to complete.
