Royal Clusters

Royal Clusters is a fantasy and medieval-themed slot from House Gaming with an RTP of 90.3%, high volatility and a maximum win of 25,000x. The game uses cluster pays, where five or more matching symbols connected horizontally or vertically create winning combinations; diagonal connections do not count, and larger clusters award higher payouts.

When a cluster wins, those symbols disappear and new ones drop from above in a tumble. Fresh symbols can create additional wins, triggering further cascades. An accumulating multiplier starts at ×1 and increases by one step with each tumble during a spin. In the base game, the multiplier resets after each spin, but during free spins it carries through the entire bonus.

Wilds substitute for paying symbols and extend clusters, though they cannot replace the Free Spins scatter. Three scatters trigger Battle Spins, awarding 10 spins with hotter reels where the multiplier can climb to ×50. Four scatters activate Royal Tales, also granting 10 spins but with even hotter reels and a multiplier that reaches ×100. Each scatter landing during the bonus round adds one extra spin to the total.

Big Chance raises the frequency of Free Spins scatters, while Ultra Chance increases scatter frequency further. Castle Raise starts each spin with a random multiplier that can reach ×100 and includes hotter reels with more Wilds. Wild Rush guarantees between 1 and 4 Wilds per spin. Choose Your Bonus allows players to select their preferred mode before a spin sequence, with different costs, volatility and feature access depending on the selection chosen.
