Cluster Kingdom Slot Review

Cluster Kingdom Slot Overview

Cluster Kingdom from ELK Studios plays out on a 5x5 board laid across a wooden table, with coins and dice hinting at old-school gambling. Instead of spinning reels, cards flip to reveal symbols, and clusters of matching icons drive the action. The medieval flavour comes through in the castles and rustic buildings, while calm music gives way to pounding heavy metal whenever a big cluster hit lands.

Each spin reveals 25 symbols, and you need at least five connecting horizontally or vertically to get paid. When a win lands, all winning icons and their identical non-winning mates vanish, then fresh cards flip in, without classic cascades dropping from above. Stakes range from 0.20 to 100 per spin, paired with a theoretical 94% RTP, mid to high volatility, a 25% hit rate, and a 10,000x max win.

Cluster Kingdom Symbols and Paytable

In Cluster Kingdom you only deal with five regular paying symbols, which keeps the paytable easy to follow. Wheat, tree, windmill, house and castle icons form winning clusters of five or more. Over 20 matching wheat symbols pay up to 25x stake, while 20+ castles can reach 250x. The other symbols sit neatly between those values, giving a steady ladder of rewards as clusters grow.

Wild symbols substitute for any regular pay icon, and a full win made only of wilds pays like the castle symbol. Multiplier wilds go a step further, sticking for the whole round and multiplying any clusters they connect with, even combining when they touch. Princess, King and Queen symbols do not pay on their own but act as feature triggers, steering much of the game's character-driven action.

Cluster Kingdom Slot Bonus Features

The Sticky Redrops feature is a big part of Cluster Kingdom. When the sticky redrop symbol lands, it picks one paying symbol, and every matching copy on the grid turns sticky while the rest of the cards flip again. If at least one new match appears, you get another redrop. Wilds and multiplier wilds stay in place throughout, while Princess, King and Queen sit idle until the sequence ends.

Multiplier wilds carry their own value and apply it to any cluster they help to form, then hold until the round finishes. When two sit side by side, their values multiply together and the total shifts onto one of them, while the other drops back to a normal wild. On top of that, the Princess can add between one and four wilds, helping clusters connect across awkward gaps.

King and Queen features drive much of the Cluster Kingdom bonus play. The King upgrades the lowest paying symbols next to him to match the highest one nearby, while the Queen rearranges adjacent cards and moves towards the King. King with Princess triggers the Mini Bonus, King with Queen gives the regular Bonus, and all three royals together launch the Super Bonus with free drops and growing multiplier wilds. X-iter can buy Bonus Hunt spins, Sticky Redrops or direct entry to any bonus.

How to Win at Cluster Kingdom Slot

Cluster Kingdom keeps the mechanics simple, so I focus on reading the board rather than fiddling with menus. Set a stake between 0.20 and 100, then look for clusters of five or more matching symbols touching horizontally or vertically. Wins remove those symbols and their twins, which can set up fresh groups. Bigger hits tend to come when Sticky Redrops, multiplier wilds or the royal features line up, all still governed by pure luck.

Cluster Kingdom Slot RTP, Volatility & Max Win

On paper Cluster Kingdom runs at 94% RTP, and long-session stats put it very close to that mark with around 93.8% returned over millions of spins. Volatility is high, with a recorded hit rate of roughly one win in four spins and a bonus about every 240 spins. The game caps payouts at 10,000x stake, and real results have reached over 9,500x, so serious swings are always on the cards.

Cluster Kingdom Slot Verdict

For me Cluster Kingdom feels like a board game night that has been turned into a slot, with just enough depth to stay engaging without getting confusing. The five-symbol paytable is easy to read, yet Sticky Redrops, multiplier wilds and the three royals keep the grid lively. I enjoy how the characters interact, slowly edging towards each other and suddenly sparking Mini, regular or Super bonus rounds.

That said, Cluster Kingdom is not a soft ride. The 94% RTP sits below many slots I play, and the high volatility means dry spells are very common, especially when the royals refuse to join up. X-iter helps if you like buying features, but it can eat a bankroll fast. I treat this one as a volatile medieval romp that can surprise with big clusters when the board behaves.
