Rainbow Riches: Cluster Magic Review

Rainbow Riches is a cluster pays slot from SG Digital with an initial four row and four columns. Many moons ago a company named Barcrest – famous throughout the UK for their real-world slot machines – released a game called Rainbow Riches. This was an Irish-themed online slots game with 20 paylines and a maximum prize of 500 times your stake. The game, which was no more than warmly received, went on to be Barcrest’s biggest online slots hit.

Since then, Barcrest (now part of SG Digital) have flogged the Rainbow Riches concept a little bit, it’s fair to say. We have seen Rainbow Riches: Drops of Gold, Rainbow Riches Megaways, Rainbow Riches Fortune Favours, Rainbow Riches Home Sweet Home … and even Rainbow Riches Slingo. In total there are eleven Rainbow Riches-related games.

Or at least there were. We now can add yet another on to the mix – Rainbow Riches: Cluster Magic.


No matter how hard you hunt at the end of the rainbow, you will not find any kind of progressive jackpot attached to this slot. The most you can hope to win is 250 times your total bet for ten or more leprechauns. Combo prizes are possible, so on a single win you could win more than that.

Play for Real Money

You won’t be able to play Rainbow Riches Cluster Magic for play money or for free in the UK because of UKGC rules. There are plenty of places to play it though for real cash, including BGO casino. This site has plenty of games and some excellent offers, so check them out.


As you may have worked out for yourself, you win amounts with this game by clusters as opposed to paylines. A cluster has to contain at least five symbols, which seems a little tight as to start there are only 16 symbols in total. Payouts are in line with your stake, which can be anything from £0.20 to £50.00. The details can be found below:

Purple Gem0.10,2512510
Blue Gem0.10,2512510
Green Gem0.10,2512510
Orange Gem0.10,2512510

There is a wild symbol too, which can be used to complete clusters using any symbol.

As is usual with cluster pays slots, any winning clusters are removed from the screen to allow new ones to fall down and take their place. What is unusual about this slot is with each cluster win, the screen configuration changes. On the first cluster win the configuration becomes 2-4-6-6-4-2. On the second, it becomes 4-6-6-6-6-4, and so on. This continues until all possible symbol positions are revealed (8 by 8). Once the cascade wins end, the slot configuration reverts back to 4 by 4.

If you manage to secure six successive cascades that you will earn yourself eight free games and a wheel spin. All free games are played with an 8 by 8 grid. With each spin (via the feature wheel) one of three features is granted:

  • Persisting Wilds: Two wild symbols will appear and remain fixed in place during your free games. Two more are added for each cascade win up to a maximum of twelve.
  • Infinity Spins: If you earn a win during a free game then one more free game is added to your total. There is a win multiplier too which increases by one with each winning free game. The maximum number of free games that can be added is 250.
  • Wild Rain: On each free game a number of wilds (between 4 and 16) are added to the reels.

In addition, if you land six successive cascade wins during free games then four more free games are added to your total. You can also ‘pay’ to change the outcome of the spinning wheel, but this option may not be available in all jurisdictions.

Graphics and Sounds

Graphically this game has the same look as all the other Rainbow Riches titles we have grown to know and … put up with. It’s a colourful look complete with a rainbow and of course the fabled pot of gold.

The sounds are just as you’d expect. The soft twittering of birds and a pleasing Irish-sounding lilt. The music and sounds become more and more hectic as you start scoring cascading wins. This does add to the effectiveness of this game,


We are seeing more and more ‘cluster pays’ games as new online slots in 2020. They all tend to be much-of-a-muchness but SG Digital (or Barcrest) should be applauded here for doing something a little different. We really like the expanding screen feature, and of course the more symbols you have available, the more chance you have of scoring a cluster win.

One of the best cluster pays slots we’ve seen this year, and a rival to Big Time Gaming’s Star Clusters Megaclusters as the best cluster pays slot of 2020. We hope you’ll at least give this title a try at one of our many recommend online casinos.
