Miner's Combo Slot Review

Cornish miners were convinced they had company in the tunnels. Little spirits called Tommyknockers 👻 lived down there and knocked on the rock 🪨, and nobody could agree on what the knocking meant.

Some said it was a warning that a cave-in was coming. Others said it would lead you to the richest vein. Either way, you shut up and listened.

To keep them happy, miners left the crimped crust of their pasty 🥧 behind. That crust was the handle they held with dirty, sometimes arsenic-stained hands, so the spirits basically got the wrapper. Cornish miners took the whole arrangement to American mines in the 1800s.

Miner's Combo slot from Relax puts me back down the shaft, and I'll be listening for knocks. I didn't bring a pasty.

Gameplay

We’re in a timber mine-shaft frame lashed together with rope, deep in a reddish-brown rock tunnel. Oil lanterns glow on both sides, a pickaxe leans in the bottom left and a chain sags across the top.

The 5x5 grid has 15 paylines that pay left to right from the 1st reel, for 3 to 5 of a kind. The RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.

RTP needs to be considered in conjunction with a game’s volatility rate. is 96.15%, the volatility is low/medium, and the max multiplier is 3,000x.

The max win is $225,000, with bets from $0.15 to $75. It's fiat currencies only, so your crypto wallet stays up at the surface.

The game breaks that return down for you: 20.39% from the base game, 9.94% from the Cash Feature, 39.88% from the Re-spins and 25.94% from Free Spins. Every Buy Bonus option also runs at 96.15%.

At the bottom of the paytable, the Shovel symbol and the A, K, Q and J all pay 1x for 5 of a kind and 0.33x for 3. The Helmet pays 1.33x (0.67x for 3), and the Potion Bottle or whatever it is pays 2x (1x for 3).

Dynamite pays 2.33x (1.33x for 3), and the Gold Cart pays 3.33x (1.67x for 3). The Wild and the Emerald share the top spot at 5.33x for 5 and 2.67x for 3.

The Wild replaces every symbol except the Free Spins Scatters and the Miner. It also pays in its own right, level with the Emerald.

The Miner can land anywhere on the grid in the base game, and he runs both the Cash Feature and the Re-spins.

Features

CASH FEATURE:

A Miner landing anywhere on the grid may trigger the Cash Feature, and that only happens in the base game. He shows a coin worth 1x, 2x, 3x, 4x, 5x, 8x, 10x, 20x, 50x or 100x, and it's paid on the spot.

Then he fades away and reveals a regular symbol underneath. Line wins count after that reveal, so the spot he was hogging can still finish off a payline.

RE-SPINS:

A Miner landing anywhere may also trigger the Re-spins. He places 1 of 3 patterns on the grid, then fades away to reveal a regular symbol.

The Wild Respin drops 5 Wilds in a diagonal line. The Top Symbol Respin plants 9 Emeralds in a cluster. The Multiplier Wild Respin lays down 5 Multiplier Wilds in a diagonal, each worth 2x, 3x, 4x or 20x.

With every re-spin, the pattern moves 1 reel to the left until it leaves the grid.

Land another Miner along the way and he adds another pattern, and patterns can cross each other or move side by side. The Re-spins end when every active pattern has left the grid.

But here’s the thing, right - the game contradicts itself on the Top Symbol pattern.

The written rules say it's 9 positions of the Gold Cart symbol, and the Free Spins intro slide calls it the Gold Cart pattern too, but the Re-spin art, the green crate, the green Free Spins Scatter and the Free Spins screen all show Emeralds.

The Emerald is the top-paying symbol (level with the Wild), which fits the name "Top Symbol" better. Still, the rules and the art don't match. And yes, I’m pedantic.

FREE SPINS:

Land 3 Scatters on reels 2, 3 and 4 to trigger Free Spins. The Scatters come in green, orange and blue, and any mix of the 3 gets you in.

Each color is linked to a pattern: green is Top Symbol (Emeralds), orange is Wild, and blue is Multiplier Wild. Whichever Scatter types trigger the round decide which patterns are active.

There's no fixed spin count. The round lasts as long as the patterns take to move off the grid, and the Wild, Multiplier Wild and Top Symbol patterns can show up on every spin.

Patterns can retrigger up to 3 times, and the round ends when all of them have left the grid. Every blue Scatter in the trigger is a vote for the 20x Wilds, so that's the color to cheer for.

BUY BONUS:

There are 4 options, and each one guarantees Free Spins with a set pattern. The Wild Respin costs 20x, Top Symbol Respin 40x, Multiplier Wild Respin 60x, and all 3 patterns combined run 200x, all at a 96.15% RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.

Performance

I spun Miner's Combo slot for a good long while and the game never stalled or froze on me.

Maximum Win

Put the max multiplier of 3,000x on the $75 top bet and the max win comes to $225,000. The minimum bet is $0.15.

Conclusion

The money lives with the Miner. Between the Cash Feature at 9.94% and the Re-spins at 39.88%, he carries roughly half of the 96.15% return.

The Re-spins alone are the biggest single slice - bigger than Free Spins at 25.94% and the plain payline wins at 20.39%. So when the Miner doesn't show, you're living off 5.33x, and that's thin gruel.

The road to the max multiplier runs through the Multiplier Wild pattern, with its multiplied Wilds lining up on paylines. Your best shot at that is Free Spins or the all-3 buy, where several patterns run at once.

On the buys, all four keep the full 96.15% RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.

RTP needs to be considered in conjunction with a game’s volatility rate., so buying doesn't cost you any return. I'd start with the Multiplier Wild buy, since it's the pattern carrying the biggest Wilds, and only reach for the all-3 buy when the bankroll can soak up a few quiet rounds.
