Cluster Kingdom Slot RTP, Details & Wager Limits
Cluster Kingdom uses a 5×5 game grid. Create winning combinations by landing clusters of 5 or more matching symbols or wilds. The bigger the cluster, the better the payout. After a winner hits, the successful symbols are blasted from the grid and are replaced by new ones. If a new winning cluster is formed, the process is repeated. These cascades keep on coming until there’s one where no new winning cluster hits.
An audience with His Majesty will set you back between 20p and £100 per spin. Click on the coins icon to choose one of the 12 different bet levels. There’s an autoplay option if you’re in an area where this is allowed. This lets you set 10, 25, 50, or 100 autospins. There’s also a quick spin mode. Neither autoplay nor quick spins are available in the United Kingdom.
The Cluster Kingdom RTP is 94%, which is below average and nowhere near the highest RTP slots. The game has a hit rate of 25%, so on average, a winner hits on a quarter of spins. The volatility is fairly high without being too brutal. On a scale of 1 to 10, the variance is about a 7. The max win is a 10,000x stake.
Theme – Highly Unusual and Super Impressive
Cluster Kingdom is a beautifully designed slot. The game grid sits on an old wooden table, with each symbol created in the style of a medieval tapestry. Rather than spinning vertically, the symbols rotate. There are only 5 standard symbols—wheat, a tree, a windmill, a house and a castle.
The jester is the standard wild, and the knight is the multiplier wild. Both substitute for all the standard symbols. The latter also multiplies the value of the winning cluster by the amount shown. There are also King, Queen and Princess symbols, each triggering its own modifier when it appears.
The slot’s visuals are superb. In spite of the topic, it’s not too serious. When you trigger the bonus rounds, you’ll see a giant Monty Python-style foot drop onto the screen. Expect plenty of ‘Carry On-style’ whistles during the features, too. The old World soundtrack morphs into something much rockier when you land a big win—it’s all superbly done. As far as new slots go, this is one of the most eye-catching ones you’ll see.

Cluster Kingdom Bonus Features
The provider Elk Studios has packed plenty of variety into this virtual trip back to the Middle Ages. You’ll find plenty of modifiers here, as well as free drops with even more extras.
Feature Symbols
Each of the three members of the Royal Family triggers its own unique modifier whenever it lands:
- King Symbol—Upgrades one symbol to a symbol that delivers a higher payout
- Queen Symbol—Her Majesty rearranges symbols adjacent to her vertically and horizontally to potentially create a new winning cluster
- Princess Symbol—Between 1 and 4 wilds are added to random positions on the game grid
Sticky Redrops
This variation on the streak re-spin bonus triggers when you land a gold C symbol and a winning cluster. You’ll be awarded re-drops, which continue as long as a new matching symbol or wild appears.
Bonus Game
Land the King next to the Queen symbol, and you’ll trigger the bonus game and six free drops. Any multipliers that land here are persistent for the remainder of the feature.
Special Bonus Game

Cluster Kingdom Verdict – Innovative Design and Gameplay
I found plenty to like in this virtual trip to a medieval court. The theme might be extremely old, but Cluster Kingdom is one of the most innovative online slots you’ll see both in terms of design and gameplay. You certainly won’t find many slots that look like this. The design team has taken great care, and the result is a real stunner.
The gameplay backs up the superb sound and visuals, too, offering plenty of variety and potential for action. The variety of modifiers and free drop bonuses, complete with extras, keep the pace high. It’s a bit unusual, so a few demo spins are recommended. You’ll find Cluster Kingdom and a host of other free play slots on the virtual shelves here at online-slot.co.uk.
The 10,000x max win is decent enough. It is a shame that the return to player rate is just 94%. That aside, there’s plenty to like about this virtual trip to old England.
