How Do Cluster Pays Slots Work?

Clusters have become increasingly popular. They eliminate that frustrating rule of a winning combination perfectly landing on an active line starting from the first or the last reel. Similar symbols just need to be adjacent horizontally or vertically to form a cluster, and it doesn’t matter where on the reels it happens. Other than that, these types of titles have all common features.

Ever since the first slot using this engine was introduced, players had fallen in love with clusters. But they pose one challenge. Usually, clusters must consist of at least five symbols, whereas in traditional slots three of a kind is a standard winning combination. Aloha! Cluster Pays, for instance, requires 9 identical symbols to secure a win.

Versatility of the Collection

The selection of the slots is extensive. One of the key factors that affect the player experience is the volatility level. You’ll have the whole range of volatility levels from low to high. Use our filter to set a specific dispersion you like. The difference is in the way winnings are spread. In low volatility slots, payouts are more evenly distributed, whereas in high volatility games wins are less predictable.

You can also choose games based on how complicated they are. Use our filters and pick the bonus features you want to have. Usually, cluster pays games feature a cascading slot engine, which is a perfect combination. Winning blocks disappear and give way to new symbols.

Some titles feature a bonus buy option and by paying the price you get a shortcut to the most thrilling part of the game. Explore a Bonus Buy collection if you enjoy this option. TNT Tumble by Relax is one of the examples for 70x bet you can get a round of free spins. The game features Indestructible Stacked Wilds, TNT blocks, and three types of bonus games players can choose from.

Aloha! Cluster Pays

Being the first cluster slot, Aloha! by NetEnt has made a huge impact. It doesn’t have many bonus features but is still incredibly entertaining to play. Try it free on our site to get a first-hand experience. Released in 2016, it still looks convincing and fresh. The game features Sticky Win Re-spins, free spins, and a mystery symbol that helps win more frequently.

Jammin’ Jars

This is another mega-hit that is enjoyed by thousands of players. Push Gaming is known for its superb quality and Jammin’ Jars is one of their most popular games. The key element of the slot is the Jam Jar symbol. It’s a wild and a scatter at the same time. When it’s a part of a cluster pay, Jam Jar doesn’t disappear from the reels like other symbols and moves to a random adjacent position. These symbols are accompanied by progressive multipliers that are applied to Jam Jar wins.

Another signature feature in Jammin’ Jars is the Rainbow bonus that gets triggered randomly when Collapse doesn’t produce any wins. The rainbow appears on the screen and leaves Giant Fruits that give another chance of getting payouts.


Reactoonz by Play’n GO is a fun cluster pays video slot that features cute little aliens. The key symbol is the Gargantoon that is asleep unless the Quantum meter is filled. When Gargantoon wakes up and storms the board, it becomes a 3×3 wild symbol that transforms into two 2×2 symbols after the first cascade and into nine 1×1 symbols after another cascade.

To charge the Quantum meter, players need a number of consecutive wins. The meter consists of five sections and after each of them gets filled, one of the Quantum features (Implosion, Demolition, Incision, Alternation) is triggered. This is a great, timeless hit that you can test for free on this site.

Star Clusters Megaclusters

The first cluster slot Big Time Gaming rolled out featured an innovative Megaclusters engine. The unique thing about it is that when wins occur, each winning symbol divides into four small ones, and all of the smaller symbols spin again giving you another chance of winning. It’s an exciting engine that has added a lot of versatility to this category of slots. Star Clusters features two types of wilds, progressive multipliers, and free spins. During free spins, the initial reel set is 8×8 instead of the main game’s 4×4.

Moon Princess

Play’n GO’s another outstanding cluster pays video slot, Moon Princess, features a unique atmosphere and anime-style visuals. There are three princesses each possessing a superpower, they appear randomly and help players win, and if you are lucky enough, all three of them will unleash their powers one by one to further improve your chances of winning.
