Cluster Kingdom Slot Bonuses and Features
Joker Wilds. Joker Wilds act as standard wild symbols, substituting for all regular symbols in the game to help form winning combinations.
Knight Wilds. Knight Wilds come with multipliers that apply to the entire cluster win they are part of. If multiple Knight Wilds contribute to the same win, their multiplier values are added together.
King Symbol. The King has a unique symbol-upgrade ability. Upon landing, the King selects the lowest-paying symbol adjacent to him and upgrades all its instances on the grid to the highest-valued symbol type adjacent to him.
Queen Symbol. The Queen can create winning clusters by switching symbols adjacent to her. If the King is also visible on the grid, the Queen moves one step closer to him after each win and before the board is refilled.
Princess Symbol. The Princess also moves toward the King, if he is on the board, after each win, following the same rules as the Queen. In addition, the Princess spreads between 1 and 4 wild symbols across the grid.
Sticky Redrops. The Sticky Redrop feature triggers randomly and selects one of the regular pay symbols. All instances of this symbol become sticky, along with any wilds and multiplier wilds, and a Redrop is awarded. New symbols of the same type will also become sticky, and a further Redrop is given. This continues until no new matching symbols appear or the grid is full. During this feature, any inactive feature symbols on the grid will remain inactive until the Redrop sequence ends.
Free Spins Bonus. The regular Bonus feature activates when the King and Queen are adjacent to each other, either horizontally or vertically. This awards 6 Free Drops, during which all wilds from the triggering spin and those appearing during Free Drops remain sticky and move across the grid.
Super Free Spins Bonus. The Super Bonus triggers when the Princess, Queen, and King are all adjacent to each other. This awards 6 Free Drops with persistent wild multipliers that increase by +1 every time they are part of a winning combination.
Mini Bonus. The Mini Bonus activates when the King and Princess are adjacent, awarding 3 Free Drops. Like the Super Bonus, this feature includes increasing persistent wild multipliers.
X-Tier Features. The game offers X-iter options for players who want to buy into certain features outside the UK:
- Bonus Hunt – 3x the bet for a higher chance of triggering the Bonus feature.
- Sticky Redrops – 10x the bet guarantees activation of the Sticky Redrop feature.
- Mini Bonus – 50x the bet triggers 3 Free Drops with persistent wild multipliers.
- Bonus – 100x the bet activates 6 Free Drops with sticky wild multipliers.
- Super Bonus – 500x the bet triggers 6 Free Drops with persistent increasing wild multipliers.
Conclusion
Cluster Kingdom slot from Elk Studios has some really nice and original features, many of which can be triggered with some of the base symbols like the king and queen. The main bonus offers persistent wild multipliers, and there’s a solid win potential up to 10,000x your stake. The only downside is Elk Studio’s familiar low RTP of just 94%.
