Diamond Mine Extra Gold Megaways Symbols/Theme


Diamond Mine Extra Gold Megaways looks almost identical to i’s predecessor, Diamond Mine Megaways. With a canyon in the backdrop, you’ll see rocks and cacti behind the reels. Inside the wooden reel frame are A, K, Q, J, 10 and 9 royals – you’ll also see shovels and pick axes, lanterns and the prospector.

There’s also a diamond symbol which is the most valuable – 2, 3, 4, 5 or 6 in combination will reward you with 2, 5, 10, 25 or 50 times your stake. There’s also a wild symbol, the dynamite sticks, which appears on the vertical reel above the main reel set – it substitutes for all symbols to help you form wins.

Uses Big Time Gaming’s Megaways mechanic

Like all Megaways slots, Diamond Mine Extra Gold Megaways uses the popular mechanic – with 6 main reel and a vertical 1×4 reel appearing above reels 2 to 5, each of the main reels can contain between 2 and 7 symbols. The more symbols on each reel, the more Megaways.

If you had 7 symbols on each of the 6 reels, you’ll play with 117,649 ways to win. This is determined randomly on each spin. Winning combinations are formed by getting matching symbols, starting from reel 1, on adjacent reels – for example, getting a diamond symbol on reels 1, 2, 3 and 4 (for 10 x stake).

Cascading Reels feature

Every time you get a winning combination, the Cascading Reels feature kicks in – this causes a chain reaction with the winning symbols removed from the reels. This means new symbols come from above to hopefully give you another win. The cascades continue until no more winning combinations are formed.

Mystery Symbols feature

Look out for the TNT symbol which is the mystery symbol – all TNT symbols will explode and transform into the same randomly chosen symbol in the Mystery Symbols feature. The only symbol they cannot change to is a scatter – they can reveal wilds or high value diamonds though.

Free Spins feature

The scatter symbol is the bag of gold – it can appear on any of the main 6 reels. If you get 4 anywhere, you will activate the Free Spins feature with 12 free spins. Every extra scatter gives you 5 additional free spins – for example, trigger with 6 scatters to start with 22 free spins.

Free Spins Gamble feature


Prior to the free spins starting, you can opt to gamble the number of free spins you’ve won – you spin the Gamble Wheel to either land on the green or red segments. Landing on green will give you more free spins and landing on red will give you less free spins. You can also choose to enter the feature without gambling – by selecting Collect.

Unlimited Win Multiplier feature

Diamond Mine Extra Gold Megaways also uses the popular Unlimited Win Multiplier feature – every winning combination increases the multiplier by 1 after a cascade. With no limits. The 1×4 vertical reel can also reveal scatters to give you additional free spins:

  • 3 scatters = 5 more free spins
  • 4 scatters = 10 more free spins

Like the Unlimited Win Multiplier, there’s no limit to how many free spins you can play with – the possibilities are endless.

Golden Bet feature

In the base game, you will see a button to the left of the reel set – this is known as the Golden Bet feature. If you activate it, you are guaranteed to land 3 or more scatters which will in turn trigger the Free Spins feature. This will set you back 50 times your stake. This option isn’t available to slots players from the UK though.

Diamond Mine Extra Gold Megaways thoughts

The Diamond Mine Extra Gold Megaways game bears a lot of similarities to the original – the real difference is the Free Spins Gamble feature where you can try your luck to win more free spins by spinning the Gamble Wheel. The RTP of 96.43% and the max win, 10,000 x stake per spin, is exactly the same.

Medium to high variance, it’s all about whether you want to gamble for extra free spins (or gold) when you enter the Free Spins feature. Despite the original being very popular, this version offers nothing different unfortunately.

Saying that, the original was very good so the Extra Gold version will prove just as popular. If you want more distinctions from this popular game engine, Monopoly Megaways (from Big Time Gaming) would be my choice.

Blueprint Gaming has since released another version, Diamond Mine 2 Megaways, which is just as good and offers different bonus features.
