Features Gems Elevator by GameArt is a 5x6 cluster slot set in a mine, where wins are formed by landing eight or more matching symbols anywhere on the grid. Winning symbols disappear after a successful cluster, allowing new symbols to drop down and create a cascade effect. The game has high volatility and an RTP range of 96.39% to 96.43%.
The feature set includes Bonus symbols, Bomb symbols, Mine Cart, John the Miner, TNT and Miner Helmet. Landing three Bonus symbols can activate a bonus feature in which their values are summed and applied as a multiplier to later wins during the cascade sequence. If three Bomb symbols land as the initial result and no wins are registered, a respin is triggered. During respins, multiplier values from Bonus and Modifier symbols are summed and multiplied by the bet value.
Players can use the demo version to play for free and practice before playing for real money. The game also includes a Buy Bonus option that takes the player directly to the Respin Bonus feature.
