Aloha! Cluster Pays is a Net Entertainment slot game with 6 reels and 5 rows – available to play on desktop, mobile and tablet devices, you can spin away from as little as 10p to as much as £200 a spin. It takes you to a tropical island where the happy Tiki is in the thick of the action. Look out for the volcano erupting whenever you get a winning combination.

This game benefits from a Cluster Pays mechanic where there are no paylines – instead, you will get wins by forming clusters of symbols where more and more of the same symbol will increase the cluster size. You need a minimum of 9 of the same symbol in a cluster to win – a symbol forms part of a cluster when it’s horizontally or vertically adjacent to the same symbol. There are stacked symbols which count as 2 symbols too to help with your wins.

In the base game only, a cluster win can randomly activate the Sticky Win Re-Spins feature – the winning symbols are held in place with all other symbols re-spinning. If the winning cluster size increases, the symbols that increase the cluster also stick with another re-spin awarded.

This continues until you don’t get a symbol that increases the size of the cluster (or you fill up the entire screen with the same symbol/cluster). Look out for the Substitution symbol which can appear on any reel – this will transform into the adjacent symbol that gives you the biggest win in a cluster.

Then you have the Free Spins feature which is triggered by getting 3 or more free spins symbols – 3 will give you 9 free spins, 4 will give you 10 free spins, 5 will give you 11 free spins and 6 will reward you with 12 free spins.

The feature benefits from a Symbol Drop mechanic where low win symbols are removed – this increases your win potential on the remaining free spins. Look out for more free spins symbols during the feature as 3 will give you 1 more free spin, 4 will give you 2 more free spins, 5 will give you 3 more free spins and 6 in a free spin will give you an additional 4 free spins.

This means there’s a potential 60 free spins in total available. Finally, if there is no win on the last free spin, you will get an additional free spin until you get a winning combination.

Aloha! Cluster Pays has a lot going on but it’s relatively simple once you get going – I found it to be nicely balanced as it’s medium variance. The maximum you win is a cool 2,000 times your stake on every spin so there’s definitely potential for big wins. All in all, NetEnt have created a very entertaining slot game with superb bonus features that are different to anything previously released – thumbs up!
