It looks more as a classic slots but having free spins feature I guess that's a plus for this game. The game has mining theme, so every symbol you'll see here is Diamond, Green Seven, Green Lemon symbols,Orange Dynamite, Orange Shovel, Gold, Orange Gremlin and the tiny Gremlin who will pop up every time you hit some winning combination. The game has also option for stake whether you'll choose to bet high or low, but being Progressive Jackpot game, it's advisable to play with high stake so the player could win the 50.000$ Progressive Jackpot.
The free spins hasn't got free spin symbol as we use to play in other games, but the point is collecting diamonds while you play, so there is a counter, so when you'll hit 3 a diamond symbols on an active line the bonus counter will highlight only 1 diamond, so you need to collect three diamonds in the counter so you could win 3 free spins. While playing the free spins feature there is no wild symbol neither multiplier, but the only thing is that you can win another free spins, which is very rare to collect another 3 diamonds.
The Jackpot can be won only if you manage to trigger 3 Gold symbols on an active pay line, but the bet need to be at least 3$, but if you selected LO instead of HI feature then the maximum award would be 1000 coins and that's the fixed payout. I have played this game only given as a free roll tournament and the last time I have played was today, but playing all this time I never managed to win something big, maybe great game but not for my taste.
