Definition of Cluster Pays
Cluster Pays refers to a unique payout mechanic in online slot games that moves away from traditional paylines. Instead of requiring matching symbols to land on predefined lines across the reels, wins are awarded when a group—or “cluster”—of matching symbols lands adjacent to one another, either vertically or horizontally. This mechanic opens up gameplay in new and exciting ways, often allowing for more dynamic grids, cascading wins, and larger payout potential.
While traditional slots depend on fixed paylines or ways-to-win (like the popular 243 or 1,024 ways systems), this model evaluates symbol proximity, rewarding clusters of typically five or more identical symbols. These clusters do not have to appear in a set order, offering more flexibility and often resulting in frequent, visually engaging wins. Many modern video slots, particularly those built on a 5×5 or larger grid, adopt this payout structure to enhance entertainment value.
Example of Cluster Pays
Let’s consider a popular online slot like Reactoonz by Play’n GO. The game features a 7×7 grid where wins are formed when five or more identical alien symbols are clustered together, touching either horizontally or vertically. When a winning cluster is formed, the winning symbols disappear, and new ones cascade down from above to fill the gaps. This may result in consecutive wins from a single spin, creating a chain reaction of payouts.
Another well-known title using this system is Jammin’ Jars by Push Gaming. Here, clusters of nine or more matching fruit symbols pay out, and wild symbols (in the form of jam jars) enhance potential wins by increasing multipliers when they’re part of a cluster.
Cluster Pays Related Terms
Cascading Reels: A feature commonly paired with this payout system, where winning symbols disappear and new ones fall into place, potentially creating additional wins from the same spin.
Grid Slots: Slots that use a square or rectangular grid layout (e.g., 5×5, 7×7) rather than traditional reels and rows, enabling the cluster mechanic to function effectively.
Tumble Feature: Another name for cascading reels, particularly when used to describe the downward movement of new symbols after a win.
Symbol Adjacency: The concept that matching symbols must touch each other either vertically or horizontally (not diagonally) to form a winning group.
Volatility: Many games using this mechanic are high-volatility slots, meaning they offer potentially large wins but less frequent payouts.
Cluster Pays Tips
– Choose Games with Multipliers: Many of the best cluster-based games include multiplier features that grow with each consecutive win. Games like Jammin’ Jars 2 or Sweet Bonanza reward repeated cluster wins by multiplying your returns.
Understand the Grid Layout: Since symbols can fall in any part of the grid, it’s important to familiarise yourself with how many symbols are needed for a win and where they tend to land most often. Some games even highlight winning clusters for clarity.
Use Demo Mode First: Because this mechanic behaves differently from traditional slots, trying out the game in demo mode is a good way to grasp the dynamics without risking real money.
Watch Out for Bonus Features: Many cluster-based games include special symbols or modifiers—such as sticky wilds, collapsing reels, or charged meters—that significantly boost win potential.
Adjust Expectations for Frequency vs. Size: While this format often delivers smaller wins more frequently, the largest payouts typically rely on landing massive clusters or triggering free spins and bonus rounds.
