Cluster Kingdom is a slot machine developed by ELK Studios, inspired by classic board games.

The reels, located at the center of the board, reveal symbols represented by playing cards that appear with each spin. This slot takes us back to the medieval era, a time when castles were majestic structures built mainly between the 11th and 15th centuries for defense, residence, and as symbols of power. Castles were often strategically located on hills or near rivers or crossroads to control and protect surrounding territories.

Released on October 1, 2024, Cluster Kingdom features 5 reels and 5 rows. Instead of traditional paylines, wins are achieved by forming a cluster of 5 or more matching symbols, connected either horizontally or vertically.

Players can place bets ranging from a minimum of $0.30 CAD to a maximum of $150 CAD. The game has a maximum RTP of 94.0% and medium-high volatility. The maximum win of 10,000 times your bet adds excitement to the gameplay, with a hit frequency of 25.0%.

You can play Cluster Kingdom for free in demo mode on the SPIKESlot website without the need to download or register for additional software.

RTP and Volatility of the Slot

Cluster Kingdom offers a Return to Player (RTP) of 94%, which is slightly below the average for modern slots, typically around 96-96.5%.

The medium-high volatility suggests that the slot tends to award prizes less frequently, but these can be relatively higher compared to lower volatility slots. This combination of RTP and volatility suggests that Cluster Kingdom provides a thrilling gameplay experience with significant wins, although it may require patience and a suitable budget to sustain play during lean periods between bigger wins.

Theme, Soundtrack, and Mobile Compatibility

Cluster Kingdom delivers a captivating visual experience, with an overhead view of a wooden table serving as the background. The reels, centrally located, display playing cards that flip with each spin. Winning combinations cause the symbols to disappear, making room for new cards to fill the empty spaces.

The soothing medieval music enhances the overall atmosphere, making each spin feel like a journey back in time.

The game is available on mobile phones, tablets, and desktop computers in free demo mode, offering a seamless experience across devices.

Slot Machine Symbols

Cluster Kingdom features 5 regular paying symbols. If you land a combination of 20 or more symbols like wheat, tree, windmill, church, or castle, you'll receive a payout ranging from 25x to 250x your bet.

There are also special symbols represented by the Princess, Queen, and King. These symbols can also activate bonus games. Additionally, you'll encounter regular Wild symbols and Multiplier Wilds.

• The King symbol upgrades a pay symbol by transforming it into a higher-value symbol, increasing the win potential.
• The Queen symbol rearranges adjacent symbols, both horizontally and vertically, potentially creating new or better winning combinations.
• The Princess symbol places 1 to 4 Wild symbols on the grid, adding more chances for significant wins.
• Wild symbols substitute for other symbols, completing or extending winning combinations.

Slot Machine Bonus Features

Redrop Sticky
When the Redrop symbol appears, the Redrop Sticky feature is activated, and a specific pay symbol is selected. All corresponding symbols become sticky, staying fixed on the grid.

If more matching symbols appear in subsequent spins, another redrop is awarded, allowing the process to continue as long as new matching symbols land.

During these redrops, both regular Wilds and Multiplier Wilds also remain sticky, increasing the chance for bigger wins.

Multiplier Wild
Multiplier Wilds not only substitute for other symbols to form winning combinations, but they also increase the value of the win. These sticky symbols remain active until the end of the round, and if two Multiplier Wilds are adjacent, their values combine. One becomes a regular Wild, and the other takes on the combined value, potentially leading to substantial payouts.

Bonus Games
When King and Queen symbols appear adjacent and connected, a Bonus Game is triggered, awarding 6 free drops. During this bonus, any existing multipliers remain active, and each new free drop can increase winnings.

Super Bonus Game
Triggered when the Princess, Queen, and King symbols are adjacent. This special game offers 6 free drops with persistent Wilds, which increase in value with every winning combination they contribute to.

Mini Bonus Game
When the Princess and King symbols are adjacent, the Mini Bonus Game activates, offering 3 free drops with similar features.
