Barkin' Clusters

Barkin’ Clusters, created by Novomatic, features a vibrant 6×6 grid set in a playful dog-themed environment filled with pups, bones, collars, and treats. The game utilizes a Cluster Pays mechanism, where winning clusters are formed by five or more matching symbols connected either horizontally or vertically. When a cluster is created, the Re-Spin feature is triggered, allowing the symbols in the cluster, along with any wilds, to remain in place while the other symbols respin. Each time a new matching symbol joins the cluster, an additional respin is granted. There are two types of special wild symbols: the Multiplier Wild, which can enhance cluster wins by up to 10×, and the Upgrade Wild, which can elevate symbols within clusters to higher-paying ones; during Free Spins, these upgrades can advance symbols by two levels. The Free Spins feature is activated by landing five or more scatter symbols, providing between 10 and 40 free spins. During these spins, the Multiplier Wild starts at 1× and increases by one with each respin, with the possibility of retriggering Free Spins. If all 36 grid positions are filled with the same symbol, Barkin’ Clusters awards a Super Cluster bonus, resulting in a significant payout in addition to the cluster win. Additionally, many versions of the game include a Bonus Bet or Ante Bet option, which slightly raises the stake for a better chance of triggering the Free Spins feature.
