What are profit clusters?
In online slots, winning clusters refer to groups of symbols that result in winnings. Unlike paylines, identical symbols do not need to line up in a row, but rather adjacent or connected in any position on the game grid, with a minimum number required. This type of symbol formation is typically associated with slot machines that do not use virtual reels, but instead operate with game pieces resembling stones.

What does "cluster" actually mean?
The term "cluster" comes from the English language and means group or grouping, sometimes also association. In general, a cluster refers to an accumulation of the same thing. When it comes to slot machines, this makes sense because most slots are about lining up identical symbols or forming them as a group.
This is how clusters are created
In order to achieve a winning cluster on a slot machine, the same symbols must form a connected field. Just like with traditional paylines, a certain minimum number is required. A cluster is considered connected only if the symbols are adjacent along their sides, without crossing over a corner. Once the required amount of identical symbols is reached, the specified payout indicated in the paytable is awarded.
Win cluster with Cascade feature.
A popular feature combination with clusters in online slots are cascades. In this mechanic, the clusters dissolve after a payout and new symbols slide from above, potentially forming additional winning clusters. Additionally, other functions often come into play, such as multipliers or free spins, which can be triggered by multiple cascades. Reactoonz by Play'n GO is a well-known example of a slot game that incorporates these features.
Online slot games featuring cluster wins
When it comes to clusters, a relatively new feature in online slots, you'll only find them in newer games. These slot machines often don't operate with reels and paylines, but instead have expanded square-shaped grids with an equal number of rows and columns. So, you can often identify a cluster slot machine just by its format.
