The Mining Fever online slot game has 5 reels and uses the 243-ways-to-win no-payline symbol combination format. That means to link up a 3-, 4-, or 5-symbol combination wins, symbols must land on the following reels 1-2-3, 1-2-3-4, or 1-2-3-4-5 respectfully.

There are 6 high paying symbols and 4 low paying symbols. The highest combination win pays out 500x the ‘BET’ value while the lowest combination win will pay out 3x the ‘BET’ value. The ‘BET’ value represents your bet per coin and not your total spin bet.

As you link up symbol combinations, you will also be rolling in 3 scatter symbols which are the 3 dwarves - 

Driler, Bombur, and Thundar. Each one has his own mining skill which that triggers a bonus spin. Each dwarves’ area of expertise in the mine will be added to the reels as feature such as wild reels or spreading wilds.

Bet sizes, RTP and Variance

To set your bets, you will need to use the ‘BET’ area’s left and right arrows. The minimum bet is 0.01 and the maximum is 2.00 which is per coin. There are a total of 20 coins placed on every spin so the min-max bet amounts are 0.20 to 40.00 per spin. With the 3 mining dwarves always hard at work digging out bonus spin wins and triggering this slot’s lucrative free spins feature, you will be rolling in combination wins. As such, the Mining Fever online slot game gives you low variance gameplay and a theoretical RTP of 96.13%.
