The setting of Mining Fever isn’t a dark and dingy cave but a five-reel underground world rich with 243 ways to win, three special bonus rounds, a free spins bonus, and lots of ways to find extra and stacked wilds. Not only are there five high-paying themed symbols but also four lower-paying icons designed so that even traditional card symbols look like part of the theme. Add a wild and three scatters and there really is a lot of buried treasure to find in this shining example of a Rabcat demo slot.

Theme, graphics & soundtrack

Considering that playing slots is often about searching for riches, it is no wonder that gold mining slots are popular. Enter the titular mine in Mining Fever and you will find yourself immersed in its rocky world. Faint candlelight picks out tracks and tools and tunnels, whilst even the generic card symbols are carved in stone. This slot has a feverish - pardon the pun - energy, from the animations speeding past in the background or accompanying winning spins to the constant lively soundtrack. There is also something of a fantasy note, with the miners being those legendary craftsmen the dwarves, who are found everywhere from Snow White to Lord of the Rings. It makes for a very fun setting.

Mining Fever RTP & volatility

When choosing a slot, you are looking for an RTP over the 96 per cent mark. Mining Fever sits comfortably above this at 96.13 per cent, which is a pretty good average return. It also has low volatility, which means that whilst individual wins may on the smaller side, they will also be pretty frequent.

How to play Mining Fever

Have you got your helmet and safety lamp? If so, it is time to start digging:

1. Take a look under the reels. There is a display for your current credits on the left, with 243 ways written underneath it. Move right and you will see your current total bet on top and the arrows of the adjustor below to set your wager.

2. An alternative for setting your bet in also under the reels, but even further to the right. If you like higher risks and rewards, click max bet - under the win display - to go straight to the top possible wager.

3. In the bottom right-hand corner of the screen is a menu button - click this for several options. The speaker mutes the volume, the gear opens the settings - in particular, a toggle for extra animations - and the ‘i’ symbol reveals the paytable, from which you can navigate pages on the game rules and bonus features.

4. Back to the main page and directly under the centre of the reels is a large, carved stone with the spin symbol on it. Click this to spin the reels once or try the small button on its left to open autoplay. You can choose 10, 25, 50 or 100 spins, but no other stopping points.

5. All that is left is to set yourself a budget with win and loss limits. Even when you are playing a free demo, it is good practice to get you into responsible gaming habits.

Bet & win sizes

As there are 243 ways to win rather than standard paylines, your total bet will be calculated by multiplying your coin bet by 20. A bet scale of between 0.01 and 2.00 means a total bet of between 0.20 and 40.00.

As you adjust your bet, the dynamic paytable will also adjust. If you start at the lowest bet, your maximum wins for each symbol will look like this:

- Jack = 0.08
- Queen = 0.10
- King = 0.12
- Ace = 0.25
- Gauntlet = 0.30
- Tablets = 0.50
- Ring = 1.00
- Chest = 2.50
- Crown = 5.00
- Wild = 5.00

Mining Fever bonus features & free spins

There are three scatters in Mining Fever, each representing a different dwarf and triggering a different bonus round. Two or more scatters means one or two bonus spins with the respective feature, while three scatters means the bonus feature will come with eight bonus spins.

- Driler’s dwarven drill

The first scatter is Driler’s. During your bonus spin, one reel will become a golden vein stacked with wilds from top to bottom.

- Bombur’s dwarven bomb

Bombur brings a fixed wild that will sit in a random position somewhere between the second and fourth reels. It will sit there for one spin but explode on the second spin, sending up to four wilds flying across your screen.

- Thundar’s dwarven hammer

Thundar’s bonus spin allows two adjacent reels - either the first and second or the second and third - to become stacked with one random symbol, increasing your chances of a winning match.

- Dwarven Gold Train

If you find three scatters of any kind, you will be awarded eight free spins and trigger the Dwarven Gold Train feature. Three dwarves will drive their train of gold across the reels, leaving a trail of wilds behind them.


Mining Fever is an exciting slot for two reasons: the combination of graphics, animations and sound that make it so lively, and the depth of bonus features. Eight free spins may not sound like much; however, combined with different bonus features and potential extra wilds, this means lots of chances to win impressive rewards. If Mining Fever has put you in the mood for treasure hunting, why not follow it up with the Where's the Gold free slot from Aristocrat?
