Testing Notes: Here’s What Happened When We Played Rainbow Riches Cluster Magic

IMPORTANT: To give you an accurate assessment of the games we review our writers play 200 spins. Whilst this is a useful tool to help us review games and to give an example of what might happen when you play, keep in mind that 200 spins is only a very small sample and cannot be used to accurately predict what might happen over another 200 spins. The outcome of all slots play is always random.

Bonus Round: 1

This is a nice-looking game for fans of the Rainbow Riches series but for me it came up short in the gameplay. It was a real slog trying to get 6 cascades in a row to unlock those bonuses and it only happened once in 200 spins. The win rate wasn’t too bad at 22%, but with small values in the paytable those payouts didn’t amount to much. After 116 spins I finally got to the bonus and landed on the Persisting Wilds. But 8 free spins only produced a win of 6.65x, which is poor after waiting so long.

Of course, on another day things could have been different, but it feels like there should be more in the base game to keep things interesting whilst trying to unlock the full grid and hit that bonus round.

What Our Reviewer Says ...

"Will suit fans of the famous Rainbow Riches brand but can be a slot to unlock the best bonus features"

Overall Score: 7.0

Theme & Design

Our Score 6

The Rainbow Riches series is well known, with more than 10 titles in the collection. If you’ve played one of them, then you’ll know the ‘luck of the Irish’ theme well. It remains largely the same throughout all of the titles, with rolling green hills, gold coins, traditional cottages, and the iconic rainbow. You’ll usually find a leprechaun too. The artwork is clean and colourful, but when it comes to imagination, the series doesn’t really shake things up too much.

RTP and Variance

Our Score 8

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next. Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

This game takes a medium volatility approach, offering the occasional larger win, mixed with mostly smaller ones. The RTP of 96.34% is really pretty decent, offering a good return that together with fair volatility should keep your bankroll going.

Maximum Win

Our Score 6

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.

The top payout of 5,000x your bet leaves a little to be desired. Many other titles in the Rainbow Riches series offer higher top payouts, including Rainbow Riches Power Mix at 12,500x your bet and the progressive jackpot title in the series, Rainbow Riches Jackpot O’ Luck. If you’re on a budget and not too worried about landing massive wins then a 5,000x haul would be nothing to complain about, especially with a solid RTP. However, jackpot chasers are advised to look elsewhere.

Symbols and Paytable

Our Score 7

Rainbow Riches is initially played on a 4×4 grid that’s surrounded on all sides by blocker tiles. When winning clusters are made, this removes some of the shamrock blocker tiles, expanding the grid to a full size of 8×8.

Instead of regular paylines, this slot uses a cluster pays mechanic, meaning you can make wins anywhere on the grid as long as you match at least 5 symbols and they’re touching either vertically or horizontally.

There are seven pay symbols plus a wild symbol too. The low value symbols are the gems (purple, blue, green and orange). These are worth 0.1x the stake for 5, up to 10x the stake for 10+. The premium symbols are the mushroom, shamrock, and leprechaun. These are worth from 1x for 5 up to 250x for 10+ symbols.

The wild symbol is a pot of gold that substitutes for any pay symbol to complete a cluster.

Features and Gameplay

Our Score 8

Each time a new Rainbow Riches is announced, there’s speculation over what the new feature will be. For Rainbow Riches Cluster Magic, the cluster pays mechanic is certainly unique, but there’s also excitement to be found in the other features.

Cascading Wins

Every time you make a winning cluster the symbols in that cluster will disappear and make way for new ones. This will continue until the new symbols stop making wins and you’ll be paid out. Every time a winning cluster hits, a section of blocked off squares becomes live.

Bonus Games

The expanding grid isn’t done at just expanding. If you manage to open all of the spaces on the reels then it will also trigger the bonus game. To expand to the full grid size, you need to hit 6 wins on one cascade.

A prize wheel will appear which you can spin to see which of the three different rounds you’ll win. If you don’t like the round that’s spun then you can choose to gamble for a different one. Be warned though, there’s a chance when gambling your round that you’ll lose it altogether.

Bonus Wheel in Rainbow Riches Cluster Magic — The bonus wheel

Infinity Games

Option one of the bonus rounds is a free spins round that gives you more spins whenever you land a win. This means that in theory, this game could keep going and going – up to a maximum of 250 free spins.

As well as this, there’s a multiplier that increases by +1 each cascade with no limit. If you don’t manage to make a win of at least 10x your bet then you’ll receive this as a consolation prize.

Persisting Wilds

Option two is a free spins round where two wilds are added whenever there’s a cascade. Wilds remain on the reels even if they’re part of a winning cluster, only being removed when a new spin is started. If you make 6 cascades in a row then this grants you an additional 8 free spins.

Wild Magic

Option three is another free spins round, perhaps the most exciting of all. This round sees between 4 and 16 wilds added to the reels. Like in the persisting wilds round, if you land 6 cascades in a row, you’re awarded 4 additional free spins.

The Final Verdict

Rainbow Riches Cluster Magic takes a beloved theme and brings a clever cluster pays mechanic, along with not one, not two, but three exciting bonus rounds. The medium volatility and generous RTP means you’re pretty likely to get to see at least one of these free spins rounds too.

While those looking for a slot that’s visually something different are going to be disappointed, everybody else should be well catered for. The middle-of-the-road max win of 5,000x your bet is counteracted by numerous features and a solid RTP. Whatever your bankroll, Rainbow Riches Cluster Magic is an exciting choice.

Useful Tips When Playing Rainbow Riches Cluster Magic

Remember, online slots are games of chance, there is NO strategy that can improve your odds of winning. However, reading our review and following these tips will help you get the most out of your time playing this slot game.
