Special features

Driler’s Dwarven Drill

Triggered by hitting 2x green Driler scatter symbols anywhere on the reels, this feature awards 1 free spin with one reel (1, 2 or 3) as a gold vein, featuring an expanded wild symbol covering the entire reel.

Bombur’s Dwarven Bomb

When the red Bombur scatter symbols appears on reel 2, 3 or 4, you are awarded 2 free spins. In the first spin, the Bombur’s Dwarven Bomb acts as a fixed wild, and on the second spin it then explodes, distributing 3 or 4 wild symbols randomly across the reels.

Thundar’s Dwarven Hammer

Triggered by hitting 2x blue Thundar scatter symbols anywhere on the reels, the feature awards 1 free spin where two adjacent reels (either 1 and 2, or 2 and 3) are filled entirely with an identical, randomly selected symbol.

Dwarven Gold Train Feature

Hitting all 3 scatter symbols anywhere on the reels triggers the Dwarven Gold Train Feature. You are awarded 8 free spins, during which the dwarves drive a 3-cart gold train across the reels from left to right, with each cart acting as wild symbol on each spin.

Graphics and Sounds

Like all Rabcat slots, Mining Fever is beautifully designed and manages to create a complete world. Set in a gold mine dimly lit by oil lamps, and with carts zipping back and forth behind and in front of the reels, there is a touch of steampunk in the style of the characters and symbols, which include various mining tools, nuggets and ingots. The animation when the special features come into play are especially exciting and give the game a great sense of energy.

The music is relatively simple and light-hearted throughout, while the sound effects are excellent, from the sound of the wooden reels spinning, to the mining carts which roar along the tracks in the background.


Mining Fever showcases some of the best features of Rabcat slot games, in that it has a range of special features that are played as part of the main game rather than as separate games, and this means that the action continues to flow at all times. As a low volatility slot, the payouts during base play are not huge but they do occur reasonably frequently and can be significantly boosted during the free spins round.

The game looks fantastic, and like all Rabcat slots there is great attenton to detail in the design and the soundtrack. In particular, the animations during the special features are outstanding, and make a major contribution to creating the imaginative world in which the game takes place.

Overall, this is a game that we thoroughly recommend, and suggest you check it out for yourself at any of our recommended UK online casinos.
