Go deep into the mines and find diamonds and gemstones, all with the help of Gustav, a Red Rake dwarf miner. You get a game with a modern game system, not entirely unique but not too common either, with pretty graphics and plenty of features, as you can learn about below.

You are getting a slot with 8x8 reels and 64 symbols visible at all times, allowing you to form your wins via Cluster Pays. Among the better features involved, expect to be able to take advantage of Cascading Reels, Wild Symbols, Re-Spins, Multipliers and more. It might not look like it, but this one’s a slot with high volatility, and with that comes a jackpot of up to 20,000x the stake, impressive even these days. RTP is not as great though, sitting at 95.50%.

Betting and Prizes

You have bets that rely on the use of 20 coins, and they allow you to set up the wager for all of them. As you select the total bet directly, the amount spent on each spin changes between $0.20 and $20.

As for the rewards that the game is capable of delivering, this is where the slot really shines. It announces that a top jackpot of over 20,000x the stake is not out of the question. Given the wagers involved, this should allow for payouts of up to $400,000.

In a game that can pay so much, the only way to do it is by making it risky for most, so that the few that win big, can become rich as a result. The volatility is then quite high. RTP is another figure to look at, and it’s a bit lower than I’d like, only 95.50% of what’s wagered being expected to go back to players.

Gustav Minebuster Slot Features

I will mention first, how winning combinations actually form in Gustav Minebuster. The game has a huge game area, with 64 symbols arranged on a 8x8 grid. You create wins by landing several matching symbols next to each other. Once a win forms, the Cascading Reels mechanic kicks in and removes its winning symbols, with a new wave then coming in and hopefully triggering additional prizes.

Gustav himself is selected for the role of the wild in this case. As such, this symbol can be included in any winning combo that is formed, provided that it’s present next to matching symbols, so that it can be part of the cluster.

As a wild contributes to a win, what follows next is a re-spin feature, where these symbols continue on the reels, though moving one position each time. A multiplier goes up by 1x, after each combo that the wilds are a part of.

Dynamite: Explosive Wins is a feature which appears to come in at random, and which will appear in one or more positions around the reels. The dynamite symbols explode, helping bring a new gemstone symbol of the same type in multiple locations on the reels.

Re-spins will follow once wins form, via the Cascading Reels, and the wilds will be sticky for that part. Get through four consecutive re-spins, and the game will trigger a free spins feature for you.

Theme & Design

The gemstone mining theme is not unusual, far from it actually, and especially for a slot machine with cluster pays. The presence of Gustav, a miner, is welcomed, but every other symbol you see on the reels will be of various types of gems, and they’re not that interesting to look at. They range from diamonds, to sapphires, emeralds, rubies and plenty more, each one in a different color and cut.


Expect a slot machine with high volatility and awesome rewards, the type of game that is popular these days. The only downside I’m seeing here is the RTP, a bit lower than expected.
