Cluster Pay slots are a type of online slot game that pays according to clusters of matching symbols. This differs from traditional paylines that pay when you get rows of the same symbols from left to right. Instead of lining up matching symbols along set paylines, players win by forming symbol clusters anywhere on the grid.

Megacluster slots are the next stage of the cluster pays slot mechanic. The mechanic was introduced by Big Time Gaming. Traditional cluster slots have a static game area, but megaclusters dynamically transform the game grid during play. Winning symbols split into smaller ones and expand the playing area.
This increases the chances to land consecutive wins and makes for more exciting gameplay. The potential for bigger payouts and exciting gaming sessions are strong selling points for megaclusters like Star Clusters Megaclusters by Big Time Gaming.
Most cluster slots can be described as cascading slots. The cascading wins mechanic is sometimes called, for example, the tumble or the avalanche feature. This twist offers exciting and dynamic gameplay, where winning clusters disappear from the grid and make way for new symbols.
This chain reaction of potential wins continues as long as new clusters are formed. Throw in multipliers, like in Sugar Rush 1000, and other modifiers, and a single drop can rack up substantial payouts. No wonder these slot games have proven popular among players.
Classic cluster pays slots offer a straightforward yet engaging twist on traditional slot gameplay. Instead of fixed paylines, these slots reward players when they land clusters of matching symbols. The symbols need to connect horizontally or vertically.

Cluster Pays slots are popular among players thanks to their innovative gameplay and unique mechanics. They stand out for their innovation, dynamic gameplay, and high win potential. Regardless of your volatility preference, cluster pays slots have something for everyone.
Let's have a look at some typical features and mechanics you can encounter while playing these slots:
Instead of traditional paylines, wins are formed by clusters of adjacent matching symbols. The minimum size of a winning cluster is usually between five and eight matching symbols connected horizontally or vertically.
This eliminates the restriction of paylines, resulting in more dynamic gameplay. This feature and a grid layout are flexible and enable providers to include unique bonus rounds and exciting themes.
When a winning cluster is formed, the symbols disappear. New symbols fall to fill the gaps. This can lead to consecutive wins from a single spin. Some games also include multipliers with each cascade to boost potential payouts.
The cascade feature can make a game highly rewarding, especially with very volatile slots.
Cluster pays slots are a more recent addition to the family of slot games. As a result of following gaming trends, many of the modern slots in this category can be highly volatile. They offer larger payouts but with less frequent wins.
These slots appeal to players who are willing to withstand dry spells for the chance at significant rewards. There are cluster pay slots, such as Aloha! Cluster Pays, which cater to low-risk players also. These low variance online slots are less common but great for players with smaller bankrolls.
Cluster pays slots are not the most common slots to include jackpots, but some of them include progressive jackpots. A small portion of each bet contributes to a growing prize pool.
These jackpots can be won by triggering specific bonus features or landing rare clusters. These additional win options of progressive jackpot slots online add to the excitement a game can offer.
Cluster Pays and Scatter Pays are two distinct mechanics in slot games, each offering unique features. Both mechanics use a grid layout, so they may be hard to separate by visuals only. Among the best scatter slots are games like Sweet Bonanza and Gates of Olympus.
The main difference is how the winning combinations are determined.
