I explored slot sites featuring this studio and revelled in the California Gold Rush excitement with the Dyn-A-Miners slot game. It's a blast, with a lively setting in a gold mine, offering classic 5-reels and 15 paylines, plus a bonus feature of 5 additional paylines..

100 Spin Test

This 100 Spin test was updated by Steve Madgwick on 26/5/2023 

100 spins is not a Real Test

We give every slot a 100 spin test to see just what it can do, or not as the case can often be - 100 spins is no reflection of the likelihood of any other 100-spin session, as RTP's are set over many millions and probably billions of spins. So this 100 spin test is just for entertainment and insight purposes

Test Comments

At just under 7 minutes, this was a pretty quick spin test, and all in all, very little happened, except 27 relatively low-value winning spins, hence the low 43% Session RTP.

The biggest base game win was an uninspiring 7.6x, and all in all the session offered little in the way of entertainment.

All is not lost however, I can confess to having played this game personally prior to it coming up on the review list and have a vague memory of a fairly handsome bonus round landing. I like this style from IGT, it is one of the most modern looking slots they have produced to date, and, the theoretical RTP is the biggest I have seem from this studio.

Game Data

Follow the game’s male and female miners into the mine shaft and see which treasures will be revealed. This slot game has fun, vivid imagery showing mining shovels, lanterns and of course the obligatory mining canary. 

During the Bonus feature, you can choose from 30 stone blocks within the mine shaft to earn up to 25 free spins with a 6 x multiplier.

Right then, let’s start digging into the in-depth review.

Graphics, Music, and Sound Effects

The visuals of the game are well-designed and bright and the cartoon style suits the feel of the game. The reel symbols include an emerald spade, ruby heart, amethyst club and sapphire diamond.

The background image shows a mine shaft filled with lanterns and giant gold nuggets, there for the taking.

The guitar twangs of the Deep South entertain you with backdrop music.

Key Features

Right, now, we’ll head into the game features which should help you decide if Dyn-A-Miners is an El Dorado or fool's gold.

Here at OLBG, we have plenty of slot games reviews which include up-to-date information about themes, paylines, bet ranges and bonuses. But stay with us to continue reading this comprehensive review of the Dyn-A-Miners game.

Theme – Gold Mine

The game’s logo includes dynamite in it which is a good indicator of what the game is all about. When you open the base game you’ll see the mine shaft filled with enormous golden nuggets and lanterns to light your way.

The reels from the base game are made up of a steely male and female character who front the game plus a canary, spade and lantern. The lower value symbols are a heart, diamond, spade and club and are attractively represented in gem colours. 

The lowest value symbol is a Scatter symbol represented by sticks of dynamite. 

It’s worth noting that the paytable is helpful and explains clearly how much the symbols are worth.


The Dyn-A-Miners game has the classic 5-reels with 3 rows per reel.


The base game contains 15 paylines, however, when the Free Spins Bonus feature is triggered 20 paylines become available to you. 


RTP or Return to Player is a way of measuring the projected return of stakes to players. It is usually between 94% and 96%. The Dyn-A-Miners RTP exceeds the average with a maximum RTP of 96.53%.

You’ll find different RTPs across numerous slot websites. We’ve put together a list of the various RTPs in some of the top UK online casinos and added these websites to our table below.

Please bear in mind that there are considerations other than RTP to think about when deciding which site to play at. You should also consider factors such as payment options, game library, customer support and welcome bonuses and deals.

You’ll probably want to venture off and try a few different slot games, so why not try some of the best slot sites we have found in our research.

Stake Range

Within the total bet section, the stake ranges from £0.15 to a mega £450.

Max Win

If a player triggers 5 Wild symbols they can win up to 10,000x of their total stake.

Wild Shape

The Wild Symbol is represented by a treasure chest image. It also works as a substitute for all symbols apart from the Bonus and Scatter symbols. This is also the game’s highest-paying symbol.

Free Spins

The Free Spins Bonus is depicted by a cart filled with gold treasures and is triggered when 3 Bonus symbols appear. Triggering the Free Spins Bonus awards an initial 3 free spins with a 1x multiplier.

During the Free Spins Bonus, 5 paylines are added to the original 15 base game paylines.

Before the Free Spins Bonus begins, you can pick from 30 stone blocks down in the mine. Picks may award additional free spins or additional multipliers.

You can retrigger the Free Spins Bonus when 3 Bonus symbols appear filled with shiny, purple gems in a cart. 


Like most modern-day slot games Dyn-A-Miners doesn't have a jackpot feature but the 10,000 x max win return should soften the blow.

If jackpot games are right up your street check out these best jackpot slot games.

Play Experience & First Impressions

The light-hearted imagery and music are entertaining and as we’ve seen from other slot games over the years the gold-rush theme is perfectly placed for a winning slots formula. The usual suspects such as autoplay and other betting options are available which most slot games have available nowadays which is great.

The base game does what it says on the tin and I found the Bonus round particularly enjoyable which I’ll discuss further in the next section.

Expert Verdict

With an RTP going up to 96.53% this is higher than a lot of slot games which is a plus. It’s a traditional game and IGT has kept things pretty simple but the format works well. Even the Bonus Feature doesn't have as much pizazz as others on the market but it doesn't detract from it being a fun straightforward, classic, slot game.

I enjoyed the bonus round and it kept me on my toes. Imagery-wise it shows another section of the mine brimming with dazzling blue and purple precious stones. There is a large wall of 30 gems and you can pick a selection to explode to see what treasure lies behind them. The game then tallies up how many free spins and multipliers you’ve won which is exciting

Dyn-A-Miners is a simple format with a timeless theme which I enjoyed reviewing. If classic games with a big RTP are your bag give it a go today, you won't regret it.
