Dragons Clusterbuster slot
Dragons Clusterbuster is a 2022 slot from Red Tiger, played on a 9x9 grid where clusters of five or more matching symbols win. At its centre sits a 3x3 Dragon Egg, and wins that land beside it break it open. The game starts with its features locked: each hatched egg releases a Hatchling feature, Blue, then Green, then Purple, and after those three a Fire Egg appears that awards 10 free spins.

How Dragons Clusterbuster plays
Wins in Dragons Clusterbuster come from clusters rather than lines. Five or more identical symbols touching each other horizontally or vertically anywhere on the 9x9 grid make a winning cluster, and with Red Tiger’s Chain Reactions those symbols then vanish so new ones can drop into the gaps, sometimes forming another win from the same spin.
The middle of the grid is taken up by the Dragon Egg, a locked 3x3 block. Whenever a winning cluster lands next to it, the parts of the egg touching that cluster break away; this is the Clusterbuster mechanic that gives the game its name. Clear every outer part and the egg hatches, the feature inside unlocks, and a Dragon Eye lights at the top of the screen to record your progress.
Dragons Clusterbuster: 9x9 grid; clusters of 5 or more matching symbols touching horizontally or vertically. Matching symbols that touch side by side pay as a cluster.
The Blue, Green and Purple Hatchlings
The eggs hatch in a fixed order, and each one unlocks a different helper. The Blue Hatchling clears the low-paying symbols from the reels, so the next cascade brings only high-paying ones. The Green Hatchling scatters Wilds across the grid, up to 20 in a spin.
The Purple Hatchling places Lightning Multipliers on up to 13 symbols. When two or more of them end up in the same winning cluster, their values multiply together, though one cluster cannot go past 100x. A 2x and a 5x in one cluster, for example, combine into a 10x multiplier.
The Fire Egg free spins
Once the Blue, Green and Purple eggs have all hatched, a Fire Egg takes their place in the centre, and breaking it open awards 10 free spins. During the round the egg block is removed from the grid, and the Hatchling features have a higher chance of triggering than in the base game. Free spins cannot be retriggered from inside the round.
Dragons Clusterbuster compared with Good Luck Clusterbuster
Good Luck Clusterbuster, which Red Tiger released in December 2022, uses the same 9x9 grid, five-symbol clusters and 3x3 centre block, but with an Irish theme and a quicker route to its bonus. Opening its Pot of Gold leads straight to 5 free spins, while four Leprechaun Wilds sit in the corners during the base game and then move about in the free spins, with their multipliers growing each time they join a win. Dragons Clusterbuster asks you to hatch three eggs first and unlocks a Hatchling feature with each one.
| Game | Released | Grid | Centre block and what it unlocks |
|---|---|---|---|
| Dragons Clusterbuster | 2022 | 9x9, clusters of 5 or more | Dragon Egg: three Hatchling features, then a Fire Egg with 10 free spins |
| Good Luck Clusterbuster | December 2022 | 9x9, clusters of 5 or more | Pot of Gold: 5 free spins with moving Leprechaun Wilds |

Frequently asked questions
How do you unlock the features in Dragons Clusterbuster?
By breaking open the Dragon Egg in the middle of the grid. Every winning cluster that touches the egg knocks away the parts next to it, and once all of them are gone the egg hatches and its feature unlocks. The next egg then takes its place, so the features open one at a time, in the same order each game.
What does the Dragon Eye at the top of the screen show?
It is the progress tracker for the eggs. There are three eyes, one each for the Blue, Green and Purple eggs, and an eye lights up when its egg hatches. With all three lit, the Fire Egg is the only one left to break, and opening it is what starts the free spins.
Does Dragons Clusterbuster use paylines?
No. It is a cluster pays game, so wins depend on groups of matching symbols that touch, not on lines across the reels. A cluster needs at least five symbols joined side by side or top to bottom, and Chain Reactions can then build new clusters from the symbols that drop in.
