Booming Games has packed a lot of humour into the 5x3 grid of symbols, with several comic dwarves smiling at you from PCs, iOS, Android, or Windows mobiles at the mobile casinos. The action takes place deep underground, where rickety-looking wooden props hold up the roof of a mine and where chunks of gold glint in the light of the miners’ lamps. Winning symbols become animated plus, there are some fun sequences that move you through the mine shaft, and where the rocks explode when you land a big win.
You can play for a wide range of stakes and thanks to some exciting bonus features, enjoy payouts of up to 1,000x the bet. A dynamite wild symbol can act as others, and in the randomly awarded Bonus Reel feature, wilds can double any wins. You’ll also find double gold symbols which can create 6-of-a-kind combinations across the 5 reels, and there’s a valuable free spins bonus round.
Look to the right of the reels and you see a series of control buttons. They are easy to use, so it’s an ideal game for inexperienced players, as well as those who have played slots for years. The bet range is also designed to suit the maximum number of players, with options from as little as 0.20 per spin, right up to a maximum of 400.00.
Take a look at the paytable, accessed via the 3 lines on the controls, to see how much you win from each symbol when you land 3 or more of the same kind across a line from the left. The gold nugget pays the most, with items such as the pickaxe and lamp worth the least.
You can set the reels spinning automatically, or speed up the gameplay in Turbo mode, and of course, it’s fully compatible with mobiles and tablets, as well as desktop computers.
There are plenty of bonus features to dig into at the best online casinos, such as a random Bonus Reel that can appear in any spin. It lowers mine carts onto the main game, unloading a mix of 3 special modifiers at once. You could see wild dynamite symbols, dynamite multipliers, double gold nuggets, or mine cart scatter symbols.
The wilds act as others to help complete combinations, while the double symbol can create the highest-paying combinations if other gold nuggets are in view at the same time. If you land 3 scatter symbols, you claim 10 free spins of the Gold Vein slot reels. During this round, wild symbols can lock in place for several consecutive spins, and any scatter symbols add 1 extra game to the total.
You can win 1,000x your total bet here, which is a little less than many high volatility slots. However, because the bet range goes up to a huge 400.00 per spin, it’s possible for high rollers to claim a big prize of 400,000.00. The average return to players percentage is 95.17%, which is decent, but not exceptional.
This is an appealing game with some fun characters on the reels and decent bonus features. The high volatility can see relatively long gaps between winning spins, but on the other hand, prizes can be quite generous to make up for it.
The Bonus Reel feature is a real highlight, and it tends to trigger quite often. While none of the extras are guaranteed to end in a win, in practice, they certainly help.
Of course, there are many mining-themed slots out there and if you like games with innovative bonuses, try Diamond Mine Extra Gold Megaways from Blueprint Gaming. You have a varying number of ways to win in each spin, plus free spins and cascading reels.
Play these games at the highest ranked online casinos. You won’t have to dig far to find them, as we feature the top sites, with the biggest bonuses, right here at gambling.com.
