The Mining Fever slot game can be found at Microgaming casinos. Microgaming as a standard now publish the house edge information of all their slots at any online casino that holds a UKGC license (this is a requirement for all UKGC licensed casinos). As such we can say that the House Edge of Mining Fever is 3.87%. When playing at any venue that does not hold a UKGC license and does not specifically publish the Return to Player information for their game, this information should be used as a guideline only as we cannot confirm whether or not this game is configurable.
Mining Fever has, as I’m sure you have worked out, a mining theme. As with most mining themed slots your characters are dwarves, which in this case amount to 3 different colourful characters, all of whom add different modifiers to the Free Spins.
Mining Fever is a 5 reel game that is 3 symbols high. Instead of paylines you form winning combinations of 3 or more matching symbols across adjacent reels, with 243 different ways to win.
Wilds – The Wild symbol will substitute for all symbols other than Scatters. There is more than one Wild symbol but the main one, the one available in the base game is a set of “Mining Tools”.
Scatters – There are 3 Scatter symbols, each one represented by a different Dwarf. There is a Red, Green and a Blue Dwarf. If you can land 2 or more of the same colour you will trigger the Free Spins feature.
Free Spins – There are 3 different Free Spins features: “Driler Free Spins”, “Bombur Free Spins” and “Thundar Free Spins”. Landing 2 identical symbols will grant you 1 or 2 Bonus Free Spins, whilst landing 3 will award you 8 Free Spins. The maximum number of identical Scatters you can land is 3 and the feature cannot be retriggered. The 3 different versions are as follows:
Driler Free Spins – These are the green Free Spins. During them one randomly chosen reel will be filled with Wilds. That reel will change with each spin.
Bombur Free Spin – These are the red Free Spins. During them Bombur Wilds can land between reels 2-4 and when they do 2 Bonus spins will be awarded. On the first spin the Bombur Wild will act as a standard fixed Wild symbol. On the second spin it will explode and 3-4 Wild symbols will be added to random symbol spaces on the reels.
Thundar Free Spins – These are the blue Free Spins. During them if a Thundar’s Hammer Wild is added to the reels you will be given 1 bonus spin. During that spin reels 1 and 2 or 2 and 3 will be filled completely with Wilds.
Dwarven Gold Train Feature – This feature is only available during the Free Spins and it sees a train of Wilds make its way across the reels. It will be made up of 3 Wilds and will move one space to the right and wither one row vertically or horizontally with each spin. Once the train falls off the end of reel 5 it reappears again on reel 1 and the process continues.
