Diamond Mine by Blueprint - Review, Free Play in Demo Mode

Set in the rocky foothills of the wild west, our hero is a grey and bearded prospector, who is attempting to uncover gold in the form of the free spins bonus round. Using TNT and cascade mechanics, symbols explode - much like the rock exploded by prospectors in the old days. When there are winning combinations, those matching symbols replaced by new ones.

A strong banjo backing track completes the obvious American country theme that runs through this fascinating Megaways slot game.

There aren't many bonus features to look out for when you play Diamond Mine Megaways slot, but the ones that do exist demonstrate the slot's wild payout potential that eclipses many 5-reel slots.

The main Diamond Mine Megaways features are as follows:

Free Spins Bonus Round

Land four scatter symbols in the base game and the free spins bonus round launches, awarding 12 free spins. If you manage to find a rare five scatter trigger, you start with 17 free spins. An unlimited win multiplier accompanies every cascade in the bonus round. Essentially, every time the player wins, the multiplier increases by one.

It is possible to retrigger the bonus - the player just needs to uncover three scatter symbols at any point in the bonus round to bag an additional five free spins. Watch out for the wild symbol, too. It can be used to substitute for other symbols to create wins.

Mystery Symbol

In any base game or bonus round spin, it is possible for dynamite to spread across the reels. They will explode simultaneously to reveal a hidden matching symbol to deliver a guaranteed win, provided it matches up along a payline. The more Megaways active when this feature lands, the better. It makes for bigger returns.

Wilds, Bonuses, and Free Spins

As we have explained, there are several features as part of the Diamond Mine slot, each of which can increase the payout potential. They are as follows:

• Wilds: Any wild symbol, represented by sticks of dynamite, can substitute for other symbols to create a winning combination.
• Bonuses: It is possible to buy the bonus feature for 100x the stake. Alternatively, you can trigger the free spins feature by landing four scatters.
• TNT Mystery Symbol: Line up TNT across the reels and watch them explode to reveal matching symbols.

As is the case with most Blueprint Gaming slots, this game has plenty of variance and volatility in the tank. Officially, its volatility is classified as medium-to-high, but it doesn't always feel that way when paying out huge amounts from massive multiplier payouts.

• RTP: 96.43% - this is a relatively high RTP in comparison to rival slots. Remember, RTP is only a guide - it means players can expect $96.43 on average for every $100 spent.
• Bet size: 0.10 - 40 - there is plenty of flexibility when it comes to staking levels. Players should always exercise caution when playing slots. It doesn’t take long for the money to disappear.
• Variance: Medium to high - this means players can expect really big wins a relatively low amount of the time, but plenty of medium to small-sized wins frequently.
