Gustav Minebuster is an 8 reel slot from Red Rake Gaming that runs on the cluster pays mechanic. This highly volatile game also has an exciting free spin feature that is capable of paying players up to 20,000x their stake.

The minimum bet required to play Gustav Minebuster is €0.20 a spin, with high rollers having the opportunity to play up to €10. There are a total of 6 stakes that you can play at ranging from €2 down to the minimum bet, this falls in line with the average amount of playable stakes that we see across all online slots within this range, and gives players a good choice in finding a bet size that matches their bankroll.

In the modern era of online slots we are seeing more and more slot providers include the cascading reels feature to their games. In the case of Gustav Minebuster you will need 5 or more symbols to be in direct contact with each other either vertically or horizontally, if this is achieved then the symbols that are part of that winning combination will be removed from the reels, and new symbols will fall down to replace them. This will continue until no further winning combinations are formed. 

During your base game play on Gustav Minebuster you will see the Dwaf wild symbol land in the play field, when this symbol appears it will substitute for all game symbols. The exciting part about the Dwarf is that when it is part of a winning combination it will not be removed from the reels, instead it will move to an adjacent position and increase to a x2 multiplying wild. The more wins it is involved in the higher the multiplier will become. 

GUSTAV MINEBUSTER DYNAMITE FEATURE

At the end of a losing spin on Gustav Minebuster the dynamite feature can randomly trigger. If this happens then one or more dynamite symbols can be added to the reels, these will explode and replace all symbols in that area with new matching gemstones. This can lead to some huge connections, and if you can get some premium paying symbols lined up there are big wins to be had from this feature. 

To trigger the free spin feature on Gustav Minebuster you will need to hit 5 or more consecutive reel cascades. You will notice to the left hand side of the reels the meter that measures your progress when the reels are cascading, and how many spins that you can achieve. We have also listed that piece of information for you below.

• 5 Cascades = 6 Free Spins
• 6 Cascades = 7 Free Spins
• 7 Cascades = 8 Free Spins

As the free spin bonus begins on Gustav Minebuster you will be greeted with 3 of the Dwarf wild symbols on the play field. These will behave in the same way as they do in the base game, so each time they make up part of a win they will move to an adjacent position and increase by x1 in value.

The ideal scenario during this bonus is for at least two of the Dwarf wilds to build up to a good sized multiplier, and then both be a part of a big winning connection, this way the win will be multiplied twice and could turn into a substantial hit.

Gustav Minebuster is certainly an interesting slot, and any game that can produce hits of 20,000x stake will grab the interest of a player. We certainly enjoyed reviewing this and it did remind us of Push Gaming's Jammin Jars, and also Dragonfall from Blueprint Gaming. This is due to the fact that both of those games are cluster pays slots, and have a very similar free spin feature.

Triggering the bonus through the cascading reels is also something different to most slots, but again this has recently been seen in both Deal or no Deal Megaways™, and Sweet Success Megaways™. Some players may find this particular method of initiating the bonus quite frustrating, especially when you keep getting blocked at the 5th cascade, or the dynamite feature triggers after the 4th cascade, but only transforms 4 symbols instead of several more like it does when you are lower down the ladder.

Overall we enjoyed Gustav Minebuster but it does seem a little like Red Rake Gaming have taken lots of successful mechanics and modifiers from different slots, and then put them all together to see how the end result turns out. It's a thumbs up from us, but some players may decide it's a little too similar to games they have played before and prefer.
