Miner’s Combo
Miner's Combo Introduction
Miner’s Combo is a mining-themed slot from Trigger Button Studios, built around a new mechanic called ComboPays. Released at the end of September 2026, the game sends an eccentric miner named Dugh underground in search of gold, with dynamite, mine carts and valuable gems filling the reels.
The real point of difference is not the familiar mining theme, but the way its special patterns move across the grid. Wilds, premium symbols and Multiplier Wilds can be placed into predetermined formations that shift one reel to the left with each respin. More than one pattern can be active simultaneously, allowing them to cross and overlap.
Miner’s Combo is developed by Trigger Button Studios and distributed through Relax Gaming’s Silver Bullet programme. It has a standard 96.15% RTP, medium volatility and a maximum win of 3,000x the stake.
Overview of Miner's Combo
Miner’s Combo is played on a 5×5 grid with 15 fixed paylines. Winning combinations are formed by matching symbols across consecutive reels from left to right.
The regular paytable mixes familiar card symbols with mining equipment and treasures, including shovels, helmets, dynamite, bottles, mine carts loaded with gold and valuable green gems.
Wild Symbols substitute for regular paying symbols and can help complete combinations across the 15 paylines. There are also special Multiplier Wilds carrying values that can reach 20x.
The character to watch, however, is Dugh. When the Miner Symbol lands, he can activate one of two outcomes. The first is an instant Cash Feature, while the second introduces one of the game’s travelling ComboPays patterns and begins a sequence of respins.
Once Dugh has completed his action, he disappears and reveals the regular symbol underneath. This means the position can still contribute to a normal payline win after the feature has been resolved.
Miner's Combo RTP, Payout & Volatility
Miner’s Combo has a standard RTP of 96.15%. Lower configurations are also available, including versions around 94.14%, 92.05% and 86.13%, making it particularly important to check which version a casino is offering.
The game has medium volatility and a hit frequency of approximately 28.7%. This makes Miner’s Combo considerably less extreme than many feature-heavy modern releases, although the moving patterns and multipliers can still produce substantial differences between individual rounds.
The betting range is 0.15 to 75 per spin, although casino and currency settings can affect the limits available.
The maximum win is 3,000x the stake. That is a relatively restrained payout ceiling by current slot standards, with Miner’s Combo placing greater emphasis on its moving ComboPays patterns than on an exceptionally large headline maximum.
Graphics & Gaming Experience in Miner's Combo
Miner’s Combo embraces a colourful, cartoon-style interpretation of underground mining. The reels sit inside a timber-supported mine shaft, surrounded by rock, wooden structures, explosives and the equipment needed for Dugh’s rather enthusiastic approach to prospecting.
Dugh himself provides most of the personality. He is less a careful miner than a character prepared to use dynamite whenever there is even the slightest chance that something valuable might be hiding behind the next rock.
The presentation becomes much more interesting when ComboPays activates. Instead of simply dropping additional Wilds onto random positions, the game clearly displays a pattern across the grid. With every subsequent respin, the entire formation moves one position to the left.
This makes the feature easy to follow. Players can see where the pattern is heading and which reels it will influence next.
The visual effect becomes considerably busier when a second or third pattern enters play. Different formations can overlap as they travel across the reels, allowing Wilds, premium symbols and multipliers to interact within the same sequence. It gives an otherwise traditional mining slot a much more dynamic feel.

Bonus Features in Miner's Combo
The main bonus revolves around the same ComboPays patterns found during the base-game respins.
There are three different Scatter types, each corresponding to one of the available patterns: Wild, Top Symbol and Multiplier Wild.
Landing the required Scatters triggers the bonus with the associated ComboPays pattern active.
The Wild Pattern places five Wild Symbols into predetermined positions. The pattern then moves one reel to the left as the feature continues.
The Top Symbol Pattern is larger, placing nine premium symbols into its formation. These positions move across the grid together, creating repeated opportunities to connect valuable symbols across the paylines.
The Multiplier Wild Pattern places five Multiplier Wilds into predetermined positions. These can carry multipliers of up to 20x, making this the pattern with the greatest potential to substantially increase individual wins.
Additional patterns can be introduced during the bonus. Up to three further patterns can be added, allowing several formations to travel across the reels at the same time.
This is where ComboPays becomes most interesting. A Wild pattern might cross a Top Symbol pattern while Multiplier Wilds move through another part of the grid, producing combinations that would not be possible from any one pattern alone. The feature continues while active patterns remain on the grid.
Features in Miner's Combo
The Cash Feature is one of Dugh’s possible base-game actions. When activated, Dugh reveals an instant cash prize ranging from 1x to 100x the stake. After the prize has been awarded, the Miner disappears and reveals the ordinary symbol beneath him, which can subsequently contribute to a payline win.
Dugh can alternatively activate ComboPays Respins. Three different patterns are available. The Wild Respins pattern introduces five Wilds. The Top Symbol Respins pattern places nine copies of a premium symbol onto its predetermined positions. The Multiplier Wild Respins pattern introduces five Multiplier Wilds carrying values of up to 20x.
Once placed, the pattern shifts one reel to the left with every respin until it eventually moves completely off the grid.
Crucially, another Miner can appear while a pattern is already active. Dugh can then introduce an additional ComboPays pattern, meaning two or even three formations may travel across the reels simultaneously.
The patterns can cross and overlap, creating the central mechanic from which the game’s name is derived.
Where permitted, Miner’s Combo also provides four Feature Buy options. The Wild Pattern feature can be purchased for 20x the stake, while the Top Symbol Pattern costs 40x. Direct access to the Multiplier Wild Pattern costs 60x.
The premium option costs 200x the stake and begins the feature with all three ComboPays patterns active, immediately creating the overlapping pattern setup that represents the game’s strongest bonus configuration. Feature Buy availability depends on the casino and jurisdiction.

Summary
Miner’s Combo takes one of the most familiar themes in slots and gives it a more unusual mechanical foundation.
Trigger Button Studios’ ComboPays system is the main attraction. Rather than keeping Wilds and premium symbols stationary, predetermined patterns travel across the 5×5 grid one reel at a time. Dugh can introduce additional patterns while the sequence is underway, allowing several formations to cross and overlap.
There are three variations to work with. Wild Respins bring five substitute symbols into play, Top Symbol Respins move a larger formation of premium symbols across the grid, and Multiplier Wild Respins introduce multipliers of up to 20x.
The Free Spins feature develops the same idea by allowing further patterns to join the initial formation. With several patterns active simultaneously, a relatively simple 15-payline setup can become considerably more dynamic.
The instant Cash Feature provides a secondary attraction with prizes up to 100x, while the four Feature Buy options offer direct routes into the different ComboPays configurations where available.
With a 96.15% RTP, medium volatility and a 3,000x maximum win, Miner’s Combo is not aimed at players chasing an enormous payout ceiling. Its appeal lies instead in the moving and overlapping patterns – a mechanic that gives Trigger Button Studios’ trip down the mine a character of its own.
