What are Cluster Pays Slots?

The traditional grid slots made use of the payline system for payouts. Ongoing revolution in the industry has birthed slots with cluster pays. This innovative format replaced the need to match symbols on a hidden line behind the reels with having a certain number of icons anywhere on the reels to win.

Matching clusters have become the primary way to win on modern slots with 6 or more reels. The way these pay mechanics are implemented can differ slightly from one game to another. What remains constant is that the more clusters you form, the larger the payout. This cluster pays slot guide will tell you everything you need to know.

Why Cluster Pays Slots Are Popular?

The main reason why cluster mechanics have become so popular is that they make gameplay more dynamic as well as feel more within the grasp of players compared to the payline mechanic. In addition to having symbols win anywhere, games with this mechanic often include cascading wins where new symbols enter the reel after every win and could trigger consecutive wins with a single spin.

Another feature that has contributed to the increase in cluster pays slot popularity is the multiplier. In Endorphina’s Starshine Crystals, the fairy at the top of the reels randomly shoots multipliers into the reels, which can turn small wins into massive payouts.

How multipliers are implemented in the grid system differs. In Gems Bonanza, spinning matching clusters can trigger a multiplier in the base title.

How Gameplay Works on Cluster Pays Slots?

Apart from the different way wins are recorded, cluster pays gameplay looks like traditional slots until the bonus rounds kick in. Once you launch the game, you will need to adjust your bet and hit the spin button. After every spin:

  • You will need at least five of the same symbols to appear to trigger a win.
  • The size of the payout will depend on the number of icons that formed the cluster.

While forming clusters with a larger number of symbols will not happen often in this unique gameplay, smaller clusters tend to appear more frequently compared to lining up icons on a payline. Here is how software developers implement cluster pays slots explained.

Clusters Pay on Adjacent Reels

In these innovative slots, you need to land 9 or more of the same symbols to trigger a payout. The caveat is that the sides of the nine icons must touch each other across adjacent reels. Even if you have more than nine symbols after a spin that don’t touch on adjacent reels, it won’t lead to a payout. A good example is NetEnt’s Aloha! Cluster Pays slot.

Cluster Pays Anywhere

In this version of slots with cluster pays, punters would be paid as long as there are 8 or more of the same icons anywhere on the screen anywhere on the reels, whether they touch or not. A good example is Pragmatic Play’s Sweet Bonanza.

Tips for Playing Cluster Pays Slots

Although the outcome of slots with cluster pays is random and controlled by RNGs, just like their traditional payline predecessors, players still need some sort of strategy for the best experience in the long run. Some of the tips that will help you better enjoy these games include

  • Learn bankroll management – Alternating your bet size will help you extend your playtime. For example, if you are playing on a $20 or less budget, you will get more game time by playing titles that allow $0.1 per spin.
  • Utilize casino bonuses and promotions – Find a casino that offers recurring bonuses with no deposit required and use the offers to extend your game time.
  • Choose cluster pays slots with the right volatility – Payout frequency will be more sparing in high-volatility titles, but significantly larger than in medium volatility titles.
