About Cluster Pays Slots
There are many different formats of online slot from classic 3-reelers to multi line games and Megaways™ slots with expanding reels. Another format that has become increasingly popular in the last decade is the Cluster Pays game. They are an exciting alternative to the traditional slot format we all know and love where payouts are collected when matching symbols land adjacent to one another on an active payline.
In Cluster Pays the action normally plays out on a grid (usually 5×5 or 7×7) and the symbols tumble down the gaming screen at the start of each ‘spin’ or ‘drop’. Wins are triggered when a cluster of symbols is formed – that is a group of identical icons that land on adjacent positions horizontally or vertically touching. As in standard slots, different symbols have different values but ultimately the bigger the cluster of symbols, the bigger your prize!
Cluster Pays games are also known as grid slots. The first famous Cluster Pays was Aloha! Cluster Pays, a tiki-themed game designed by NetEnt. Since then, hundreds more have been released onto the market and slot sites in the UK are packed with them.
As well as the Cluster Pays mechanic these slots typically include other features like Cascading Wins, Free Spins and Multipliers. In this article we have put together a list of our 10 favourite Cluster Pays slots with mini reviews to tell you how they work. You can find them at pretty much all the casinos reviewed on our site.
