Dragons Clusterbuster Slot RTP, Details & Wager Limits

Reels/Paylines: 9×9 grid + Cluster pays

Stakes Range: 20p to £10 per spin

Max Win: 7,931.2 x stake per spin

RTP: 95.78%

The Dragons Clusterbuster slot is played on a 9×9 grid and uses the cluster pays mechanic. Five or more matching symbols landing horizontally or vertically will result in a winning combination. Winning clusters then disappear to allow the above symbols to fall into the clear positions, which gives you a chance for even more wins on each spin.

Stakes range from just 20p up to £10 per spin. You’ll see the total bet below the reels. Simply use the + and – buttons to change your bet. Autospins are also possible in most territories, but this is not an option anymore in the UK.

The Dragons Clusterbuster RTP is 95.78%, which is bang on the average for an online slot. Being a high volatility slot, we expect the return to player rate to be around this figure, to be honest.

The maximum win here is 7,931.2 x your stake, which isn’t too bad, although it’s not as good as some other slots on the market. Your best chance of landing this is during the Free Spins feature where you can unlock the blue, green, and purple eggs for potentially big wins.

Theme – unlock the hatchling features

Theme: Fantasy

High Value Symbol: Crown

Compatibility: Mobile, Tablet, Desktop


With its fantasy theme, the Dragons Clusterbuster slot game brings a magical feel to everything with the feature film-like audio and the sound effects of a glowing egg in the middle of the grid. It almost gives you the feel as if you’re going on a journey with every spin.

Things intensify once the Free Spins feature is triggered, although we found that it can take a long time to happen as you first have to hatch the blue, green, and purple eggs first. Dragons are unleashed to cause havoc on the grid during the bonus round, and the audio sounds as if you’re about to go into battle. It makes for really exciting gameplay.

You’ll notice the usual A-10 royals on the grid, which are the low paying symbols. These are joined by the higher paying scroll, swords, globus cruciger, and crown. The crown is the most rewarding symbol, paying from 1.5 x your stake for 5 in combination up to 50 x your stake for 20+ in combination.

Dragons Clusterbuster Mobile


Produced using HTML technology, the Dragons Clusterbuster mobile slot can be enjoyed on all Android and iOS devices. While we prefer a desktop as it shows everything in more detail with the large 9×9 grid, the HD visuals on smaller devices certainly don’t let it down at all.

Dragons Clusterbuster Bonus Features

There are 5 main bonus features in the Dragons Clusterbuster slot excluding the cluster mechanic. From the hatchling features to free spins and the Clusterbuster, there’s a lot going on. Let’s explain each feature to you so that you have a much better understanding of how the slot works.

Chain Reaction

Any symbol that is part of a winning combination will disappear from the grid. New symbols will fill those positions and they too could form new wins. This process continues until no new wins are formed.

Clusterbuster feature

There’s a 3×3 block in the middle of the grid that is inactive, to begin with. The outer tiles will unlock once winning combinations are formed next to it. You simply need to break all of the tiles in the 3×3 block to unlock the prize that awaits, which leads us nicely on…

Dragon Eyes Progress feature


All of the dragon’s features are locked at the start of the game. You must hatch the dragon eggs to unlock them. They will unlock 1 at a time, starting with blue, then green, then purple, and then the Free Spins feature after that.

Only 1 dragon egg will be active at a time.

Once you break all of the tiles around the first blue egg, the egg hatches to award its feature and a dragon eye will appear above the grid to tell you that the feature is available in the game.

When you unlock a feature, it’s triggered on the next spin and the next egg is placed in the 3×3 block ready to be unlocked in the same way as the first one. All of these unlocked features can trigger randomly in any future spins.

The order you need to hatch the eggs in is Blue > Green > Purple. Once these 3 different coloured eggs have hatched, a Fire Egg appears in the 3×3 block, which needs to be unlocked in the same way as the others. The Fire Egg awards 10 free spins every time it’s hatched.

It’s important to note that if you change your stake, it will reset the features and the eggs. So, for example, you’re betting £2 a spin and have unlocked 2 eggs. By changing to £1 per spin, everything is reset, so our advice would be to stay on the same stake if you have these features available.

Hatchlings feature

You can unlock eggs as you spin away, but what are they and what do they give you? Here’s a helpful table showing the features of the 3 eggs:

Blue Hatchling Destroys all low paying symbols when active.
Green Hatchling A dragon flies above the grid randomly adding up to 20 Wilds
Purple Hatchling This feature will create a Lightning Multiplier and add it to a number of random symbols.

The possible multipliers range from 2x up to a maximum of 100x.

Free Spins  feature


After all 3 eggs have been unlocked, there is 1 more to go. This is the Fire Egg, which gives players 10 free spins once it’s unlocked. During the bonus round, there’s an increased chance of triggering 1 or more of the Hatchling features.

What’s also great about this feature is that the Fire Egg locks in place and can be unlocked again for another 10 free spins. The eggs do not reset unless you start playing at a different bet level.

There are no free spin retriggers available.

The Dragons Clusterbuster slot is a very fun creation by Red Tiger. We enjoyed putting it through its paces, and we were impressed by the offering overall. The bonus features are the main selling point here, with the eggs being the main focus of everything that occurs on the grid.

The soundtrack, albeit repetitive, is good, and the visuals are fantastic on any device. But the only negative we really have here is that it can take a long time to hatch all 3 eggs. Some may enjoy the patient wait, but for those who love getting straight into the bonus features, this one may not be for you. Give our free demo a go and make your own mind up.

Overall, it’s a new type of game to try. Many players will love it, but there will be some that don’t. In our opinion, it’s a hit and the bonus features are great once they’re all unlocked.

Other top grid slots to consider include ELK’s Mystic Orbs, which has a max win of nearly double this one. But if you want to stick with the theme, it’s all about the Dragonfall slot by Blueprint Gaming. Not only does it come with some exciting features, but it also has huge max win potential at 50,000 x your stake.

  • 7,931.2 x stake max wins
  • Great bonus features
  • Fun to play on mobile
  • Can take a while to land Free Spins

Dragons Clusterbuster FAQs

What is the Dragons Clusterbuster RTP?

The Dragons Clusterbuster RTP is just below average at 95.78%. But being a highly volatile slot, don’t expect big wins too often compared to a slot with lower variance.

What is the Dragons Clusterbuster max win?

The max win is 7,931.2 x your stake, which is pretty reasonable, although we had hoped for it to be at the 10,000 x mark or even above that. The Free Spins feature is your best chance of landing this max payout.

Are there any Dragons Clusterbuster free spins?

Yes, you can trigger the Free Spins feature by unlocking the Fire Egg in the 3×3 block. However, it’s important to note here that you need to hatch the blue egg, the green egg, and the purple egg before you have a chance of landing the Free Spins feature.

Is there a Dragons Clusterbuster demo?

Yes, the Dragons Clusterbuster demo is available here at Online-Slot.co.uk. Hatch those eggs on mobile, tablet, PC and/or laptop devices as desired. We have over 4,000 slot demos in total to play.
