Cluster Games are all the rage, almost as popular as Megaways games. Their playability on mobile, in particular, sees them regularly appear in the most popular online slots list in many a casino providers’ catalogues. What better series of online slots to enjoy Cluster Pays reboot than the Rainbow Riches franchise, which has scores of other titles to its name. The iconic Rainbow Riches Leprechaun returns as a game symbol, and to win in this game you must match symbols like him and others in clusters of five or more. With each win the game board expands to allow more symbols and more cluster wins before ultimately triggering the game’s bonus features. The lilting Irish folk tune that plays over the top increases an octave with each win – a lovely touch.

How to Play
Cluster Pays games revolve around matching symbols in groups – or clusters – to find wins. Rainbow Riches Cluster Magic requires a minimum of five matching symbols in order to find a winning combo. Like in Big Time Gaming’s Star Clusters Megaclusters slot, each win expands the reelcase to allow more symbols to cascade down and create further winning combinations. To set your bet level select the left or right arrows either side of your bet display. Once you are happy with your bet either press the large green spin button to set the cascades in motion or select the auto-play function beneath the spin button.
The low-paying symbols in Rainbow Riches Cluster Magic are a series of glistening Gems. This is a welcome departure from the standard 9s through Aces that were present in the original Rainbow Riches slot, as well as seemingly every other Rainbow Riches sequel following it. These lower-paying gems only pay x0.1 for landing five in a cluster – the minimum required to trigger a payout. The Toadstool and Shamrock offer x0.25 for five in a cluster, while the top-paying Leprechaun boasts a x1 payout and x250 for landing him in a cluster of 10 or more. The Pot of Gold Wild substitutes for all symbols, though doesn’t offer an additional payout when it completes combos.
The Free Spins feature offers three varieties, activated by expanding the game board to its full size from 4×4 to 8×8.
