Miners Combo Slot Review
Dugh’s idea of careful mining involves dynamite, and quite a lot of it. Gold, diamonds, mine carts and lit fuses crowd in around him, all drawn in loud cartoon colours that don’t pretend to be a real mine for a second.
Miners Combo sets that up on a compact 3×5 grid with 15 fixed paylines, an RTP of 96.15%, Medium volatility and a top win of 3,000x your stake. Behind it sits Trigger Button Studios, one of the developers building through Relax Gaming’s Silverbullet programme.
Their catalogue also holds Beanstalk Grows Wild and Sticky Rabbit. Fire in the Hole is the closest thematic neighbour, though that one runs on expanding grids rather than the travelling ComboPays patterns this is built around. Miner’s Combo is also the first Trigger Button Studios slot to debut the new ComboPays™ mechanic. Instead of relying on static reel features, ComboPays™ patterns move across the reels, combining and overlapping to create changing win opportunities throughout the game. Trigger Button Studios also plans to use the ComboPays™ mechanic in future releases.
Base Game & Features
Three columns, five rows, 15 fixed paylines. Stakes run from 0.15 to 75 per spin, and the line count doesn’t move whichever end of that you play at.
The symbol set is standard mining kit: shovels, barrel helmets, potions, dynamite sticks, gold carts and emeralds, sat above J, Q, K and A royals.
Emerald and wild share the top of the paytable, paying 80 for five of a kind, 60 for four and 40 for three. The gold cart follows on 50, then dynamite on 35, the potion on 30 and the barrel helmet on 20, with the shovel level with the royals on 15.
Hit frequency is listed at 28.69%, and the base game plays to that number rather than against it. Something lands often enough that long dead stretches were rare in our session, even if plenty of those hits were small.
Dugh is the symbol to watch in the base game. When he shows up he can load the reels with one of the ComboPays respin patterns, or smash open an instant cash prize.
Wild and X Wild Symbols
The standard Wild substitutes for everything except the Bonus and Cash symbols, and doubles as a joint top payer with the emerald.
The X Wild is the multiplier version, boosting the wins it lands in. It’s the symbol the Multiplier Wild Respins are built on.
Cash Feature
Dugh can also break into a hidden pocket of treasure in the base game, revealing an instant cash prize worth up to 100x your bet.
Once that prize is collected, the regular symbol underneath is uncovered and can go on to form part of a line win.
Miners Combo Bonus Features
ComboPays is the mechanic everything else hangs off. A pattern lands on the grid and then shifts one reel to the left with every respin, travelling across the reels in a single, readable direction.
If Dugh appears again while a pattern is running, a second joins it. Two or three patterns can then occupy the same space at once, which is where the combinations get interesting.
ComboPays Respin Patterns
There are three respin types, and each one changes what the travelling pattern is carrying:
- Wild Respins – five wilds surge onto the reels to build extra combinations.
- Top Symbol Respins – top symbols roll on, carrying premium prize potential.
- Multiplier Wild Respins – multiplier wilds worth up to 20x boost every win they touch.
Top Symbol Respins work differently to the other two, since the value depends on where the loaded premium ends up as the pattern moves.
Multiplier Wild Respins are the highest-ceiling version of the three, and the multipliers apply to any win the travelling wilds land in.
Miners Combo Free Spins
Three scatters trigger the free spins, and each of those scatters activates one of the three moving ComboPays patterns.
The patterns keep travelling as the round plays out, combining and overlapping as they go. Retriggers add up to three further patterns on top.
Because every pattern moves the same way, a screen carrying several at once still tracks. You can see which ones are about to occupy the same reels.
Bonus Buy
Miners Combo carries four bonus buy options, ranging from single-feature routes through to a combined purchase that puts every ComboPays pattern in play at once.
The cheaper routes are the quick way to see the mechanic. The feature-heavy option is the one that reliably produces the overlapping setup the game is designed around.
Our Honest Verdict
The base game was busier than expected, with hits coming round often enough that few stretches ran flat, and Dugh turning up to break up the quiet ones.
Wild Respins are the weak link of the three: five wilds land, some lines fill, and that’s the whole idea. Top Symbol Respins were better than that, dropping a premium into a pattern that then carried it somewhere useful.
Multiplier Wild Respins were the pick, and free spins with two or three patterns crossing each other was the version worth playing. The best sequence came when a Multiplier Wild pattern joined one already travelling and the two shifted through each other, paying as they went.
Nothing close to 3,000x, and that ceiling is modest enough that top-end hunters should look elsewhere. Everyone else gets a mechanic you can actually follow, on a grid small enough to watch it develop.
Dugh makes a great deal of noise for a game that pays in steady instalments.
Overall Rating: 7.9/10
