1. Bonanza Megaways (Big Time Gaming)
- RTP: 96%
- Max Win: 26,000x
- Volatility: Medium-High
- Stakes: 20p to £5
- Release Date: 7 December 2016
No mining slot list is complete without Bonanza Megaways, the game that launched a thousand clones. Released by Big Time Gaming in December 2016, Bonanza, as it’s affectionately known, was the first to popularise the Megaways mechanic.
With 6 reels and up to 117,649 ways to win on every spin, it’s playable from 20p per spin. With Reactions for continuous wins and cart-track wilds, the focus is on the Free Spins feature, where you begin with at least 12 free spins. Beginning with a 1x multiplier, every Reaction/win triggers the Unlimited Win Multiplier feature, meaning the multiplier increases by 1 each time, with no limits.
With unlimited retriggers, Bonanza offers 26,000 x bet max wins and is Megaways royalty. Still the gold standard for reactive, high-potential mining slots, it’s a must-play classic.

- Volatility: Extreme
- Stakes: 20p to £5
- Release Date: 22 February 2024
Building on the chaos of the original, Nolimit City’s Fire in the Hole 2 turns everything up. Beginning with 6 reels and 486 ways to win, this extremely volatile slot can be played from 20p a spin.
With a total of 11 bonus features, Collapses lead to more ways to win (up to 46,656). There are xBomb Wild Multipliers, xSplit symbols, Buried symbols that reveal xBomb Wilds, Bonus Scatters or xSplit symbols. In the Wild Mining feature, up to 6 symbols are replaced by xBomb Wilds which leads to explosive wins.
It’s all about the Lucky Wagon Spins feature, where enhancers and persistent symbols can lead to 65,000 x bet max wins. It’s proven so popular that NLC will release Fire in the Hole 3 (in June 2025).

- Max Win: 70,000x
- Volatility: Extreme
- Stakes: 20p to £5
- Release Date: 15 March 2022
Forget cheerful dwarves, this one focuses on an angry dwarf’s mission to find the ultimate beer recipe. Again, from Nolimit City, Misery Mining is a slot for the brave. Beginning on a 3x3 block with 27 ways to win, you can play from just 20p per spin.
With a Collapsing Mine feature, exploding xBomb Wild symbols remove barriers for more ways to win. Increasing the win multiplier by 1, the reel area can increase to 7x7 in size with 823,543 ways to win. With Scatter or Super Scatters transforming into xBombs when not part of a win, the focus is on the Misery Free Spins feature.
Here, you choose between Mouse or Rat Mode: Mouse Mode is a high volatility feature, whilst Rat Mode is in the extreme volatility bracket. In either, look out for the Top Row, which reveals enhancers on every free spin. With 8 enhancers, there are Side and Bottom Collectors, which are activated by certain enhancers for explosive results. More of a psychological thriller than a gold rush, it offers 70,000 x bet max wins.

Appearing on all 5 reels, the Nudging Mystery Stack symbol nudges to take over the whole reel with up to 8 symbols per reel. Also revealing the same symbol, he’s worth his weight in gold as it can lead to 32,768 ways to win!
In the Mega Free Spins feature, there is a minimum of 6 free spins awarded. Down in the mine, Nudging Mystery Stack symbols appear more frequently for a higher number of ways to win: these also reveal stacks of wild symbols for 50,000 x bet max wins.

A follow-up to the Fire in the Hole slots and Misery Mining, Dead Canary is by Nolimit City. The angry dwarf is back, but this time in search of true love. With 6 reels and 36 ways to win, you can play from 20p a spin. Collapses play a big part and unlock rows for up to 1,728 ways to win as well as multipliers.
With a Wild Mining extra with an increasing win multiplier, xBomb Wilds explode in a cross pattern to increase the win multiplier. In the Canary Free Spins feature, Bomb explosions open up vaults which collect coins and multipliers from adjacent positions.
With various Enhancer symbols, the dwarf and rat ones are important as they are persistent collectors or payers. Offering 65,000 x bet max wins, this explosive slot game has the same grid layout/mechanics as Nolimit City’s The Cage.

This game was the first to use the Megadozer mechanic, which is prevalent in the Megadozer Free Spins feature. Beginning with at least 12 free spins with a 1x multiplier, there is a Megadozer where Bonus Coins land (think of ITV’s Tipping Point game show). When Bonus Coins fall into the reels, they award wild multipliers up to 5x, individual symbol multipliers up to 10x, extra free spins and increases to the overall win multiplier.
With a Win Exchange feature, Bonanza Falls comes with a high 96.51% RTP rate and huge 93.540 x bet max wins. Highly recommend if you’re a fan of the original game but want more extras and much higher win potential.
