Bonus Features

You won’t find any of the ‘usual suspects’ of bonus features here. Instead, there is an innovative Cluster Lock feature, symbol upgrades, and a valuable multiplier.

Locked Clusters

The game’s symbols can appear as larger versions of themselves, up to 3x3 in size. When you land winning combinations, the symbols involved will be locked in position. A respin is activated and if any new matching symbols are added to the original cluster, they are also absorbed into the cluster and the process repeats. The game will keep generating respins as long as new winning combinations keep being formed. If you fill all reel positions with winning clusters, you will gain a 2x multiplier on your winnings.

Crown Upgrade

A randomly-generated crown symbol can appear and upgrade the symbols of any visible cluster to higher-value symbols.

Playing the Game

This title is easy to play once you get used to the format and features, which are a bit unusual as far as classic slots go. All the important game controls, including Autoplay, bet and spin speed adjustment, and audio can be controlled via the main screen.


Royal Gems slot breaks away from the standard online slot format with an intriguing and rewarding feature selection. The game looks great and Red Tiger has gone out of its way to appeal to mobile game fans with candy crush-like chunky colourful graphics. I enjoyed the interplay of the cluster pay mechanic and the locked cluster feature which can generate an impressive chain of wins as more and more symbols stay fixed on the reels, and the random Crown Upgrade created some truly exciting moments.

The game’s winning potential tops out at a modest $60 000, but the friendly variance means you can look forward to a fair win-to-spin ratio. If you’re looking for a cluster pays slot with a bigger jackpot on the line, try out Dungeons and Diamonds or Lucky Leprechaun Clusters.
