Diamond Mine Megaways Slot Details & Wager Limits

The Diamond Mine Megaways slot uses the classic Megaways engine from Big Time Gaming. The action plays out on a 6 reel machine with the number of symbols appearing on each of those reels changing with each spin. The more symbols in play, the higher the number of active Megaways.

If the reels reach their maximum configuration, you’ll have 117,649 ways to win. To create a winning combination, you’ll need to land 3 or more matching symbols or wilds on adjacent reels, starting from reel 1.

Stakes start at 20p per spin, rising to a maximum of £100 for high rollers with deep pockets. Just click on the stake size button to the left of the reels then choose from the selection of stake levels. Alternatively, just move the arrows up or down until you find the level you’re comfortable with. You can run between 10 and 100 autospins if you wish. There are also options to set win and loss limits.

The Diamond Mine Megaways RTP of 96.43% is slightly better than the slots average. Compared to Megaways slots RTP rates, it’s just below the top rates.

The theme here is explosive and that’s the case with the variance too. The Diamond Mine Megaways volatility is high. With the bigger wins coming in the free spins, the max win is 10,000 x your total stake per spin or free spin.

Theme – Audio & Design Features – go digging for riches


There’s nothing overly flashy about the design in the Diamond Mine Megaways slot. Set against a mineshaft backdrop, it has a mining theme. The imagery here is done cartoon-style and is rather basic.

The symbols, appearing on blocks of stone, are bright, colourful and stand out clearly though which is more important than visual flair. The hillbilly soundtrack twangs along rather nicely in the background while you spin to create plenty of atmosphere.

Joining the A to 9 royals are axes and spades, a lamp and a rather jolly looking diamond prospector. Top of the bill as far as payouts go is the diamond. Land 2, 3, 4, 5 or 6 of these in combination for an award equal to 2, 5, 10, 25 or 50 x your total stake. There are also wild, scatter and mystery symbols.

You can try and blow up a jackpot while playing on a smartphone or tablet as well as via desktop or laptop computer. The bold visuals and relatively straightforward gameplay combine nicely on the Diamond Mine Megaways mobile slot.

Diamond Mine Megaways Bonus Features

You’ll find many of the elements that have made Megaways such a game-changer in Diamond Mine Megaways. You’ll find mystery symbols and a free spins round with expanding multipliers here.

Cascading Reels feature

Each time you land a winning combination, a cascade takes place via the Cascading Reels feature. That means the winning symbols are removed with new symbols dropping in to replace them. If this creates a new winning combination, the process is repeated. The cascades keep on coming until there’s one where no new winner is formed.

Mystery Symbols feature

The barrel of TNT is the special mystery symbol. All examples of this symbol that appear on the same spin transform into the same symbol with the Mystery Symbols feature. A payout consideration is then made with the new symbols in place. The mystery symbol can transform into any standard symbol and even the wild but not the scatter.

Free Spins feature


Land 4 sack of gold scatter symbols on the same spin and you’ll trigger the Free Spins feature. You will be rewarded with 12 free spins for 4 scatters. Each extra scatter on the triggering spin adds another 5 free spins to that total.

The free spins start with a standard 1x multiplier in play. Each time you land a winning cascade, the Unlimited Win Multiplier feature kicks in. As a result, the multiplier increases by 1. There’s no limit to how high the multiplier can go. It won’t reset to 1x following an unsuccessful cascade either.

Retriggers are possible here too. Landing 3 or 4 scatters on the same free spin will add another 5 or 10 free spins to your total. Like the multiplier, the number of free spins is unlimited.

Diamond Mine Megaways Review Summary – a cult classic for good reason

The cartoonish visuals, banjo-heavy backing track and classic Megaways features have combined to make the Diamond Mine Megaways slot something of a cult favourite with slots players.

It is almost identical to Bonanza Megaways from Big Time Gaming which is by far the most popular Megaways game. 1 thing that is different is the 96.43% RTP compared to Bonanza’s 96%.

The bigger wins will come from the multipliers in the free spins as the multiplier can increase infinitely. You just need plenty of successive wins to achieve that. If you like Megaways, you should try Odin Infinity Reels Megaways by ReelPlay which also uses the Infinity Reels engine for an infinite number of ways to win.
