Rainbow Riches Megaways Slot RTP, Details & Wager Limits

Reels/Paylines: 6 reels +up to 117,649 paylines

Stakes Range: 20p to £20 per spin

Max Win: 12,500 x

RTP: 96%

The Rainbow Riches Megaways slot is played on a 6 reel machine. The Megaways engine means that the number of symbols on each reel changes on each spin. You can see between 2 and 7 symbols on each reel.

The number of symbols changes the number of active Megaways. When offering the maximum number of symbols, the number of ways to win is 117,649. To create a winning combination, land 3, 4, 5 or 6 matching symbols or wilds on adjoining reels, starting from the leftmost reel.

You can join the lucky leprechaun here at stake levels of between 20p and £20 per spin. Click on the plus and minus buttons just below the main Spin button to select your bet accordingly. There’s also a basic Auto Play function which allows up to 100 autospins with loss and single win limits.

The Rainbow Riches Megaways RTP is 96% which put is slap bang in the middle of pack. What isn’t midrange though is the variance. The volatility is very high.

The maximum win is 12,500 x your total stake per spin. The key to big wins in the free spins due to the increasing multiplier which can rise infinitely.

Theme – spin up massive mischief with everyone’s favourite leprechaun

Theme: Irish Luck

High Value Symbol: White Gemstone

Compatibility: Mobile, Tablet, Desktop


Fans of the original Rainbow Riches will find plenty that’s recognizable in the souped-up Rainbow Riches Megaways slot version. With developer Barcrest keeping true to the classic game, it has the same Irish luck theme.

The design is simply done. The reels are set against a backdrop of green fields and a rainbow with a pot of gold lying at the end of it. There’s a typically jaunty jig of a soundtrack playing while you spin. It matches the Irish fortune theme nicely. There’s nothing too flashy here but it remains true to the original brick and mortar casino slot.

Symbols on the reels include lower value royals and potentially more rewarding gemstones. The pick of the bunch is the white gemstone. Land 2, 3, 4, 5 or 6 of these on adjoining reels and you’ll pocket an award equal to 2, 5, 10, 25 or 50 x your total stake.

Boosting your winning chances is the lucky horseshoe wild. That substitutes for all the standard symbols when it makes up part of a winning combination. You’ll also come across Super Gem and Pot of Gold Bonus symbols.

Rainbow Riches Megaways Mobile


The Rainbow Riches Megaways slot is available to play on all devices including mobiles, tablets and desktops. The bright, colourful visuals work very nicely in the mobile version. So too does the relatively straightforward Megaways gameplay.

Rainbow Riches Megaways Bonus Features

The design in Rainbow Riches Megaways will be very familiar if you’ve played the original slot. The gameplay, not quite so much. It will be familiar if you’ve played Megaways slots before though. With 7 bonus features, feature highlights include cascading reels, mystery transforming symbols and free spins with an increasing multiplier.

Cascading Wins feature

This game comes with a Cascading Wins feature. When you get a winning combination (formed by matching symbols on adjacent reels beginning from reel 1), the winning symbols are removed and replaced by new ones. This gives you the opportunity to win again and again from every spin. The cascades keep on coming until no further wins are created.

Super Gem Bonus feature

Land a rainbow-coloured Super Gem symbol in the top reel window to trigger the Super Gem Bonus feature. All the gemstone symbols on the reels morph into the same matching gem symbol. A new payout calculation then follows with the newly transformed symbols in position.

Free Spins Bonus feature

rainbow-riches-megaways-slot-free-spins-bonus-feature To trigger the Free Spins Bonus feature, you’ll need to land 4 pot of gold bonus symbols on the same spin. You’ll then go on to play 12 free spins. An extra 5 free spins are awarded for each additional pot of gold that appears on the triggering spin. For example, landing 6 bonus symbols for example will give you 22 free spins.

Just like in the base game, landing a winning combination triggers the Cascading Wins feature. The successful symbols are removed from the grid and new ones replace them. The cascades continue until no new winner is created.

However, each cascade brings the Unlimited Win Multiplier feature into play. When you get a win, the multiplier increases by 1. These multipliers don’t reset following an unsuccessful cascade either, they keep on rising throughout the feature. The multiplier starts at 1x. There’s no cap on how high it can go either.

You can add extra free spins to your total tally. The +1, +2 and +3 symbols that can land in the top reel do exactly what they say on the tin, adding 1, 2 or 3 more free spins each time they appear. There’s unlimited free spins up for grabs.

Buy Pass feature

In some territories (but not the UK), players will have the chance to buy the Free Spins Bonus feature for a fee of 100 x stake. This will see you rewarded with 12 free spins. The RTP also increases to 96.66%.

Take a Chance feature

There’s also a Take a Chance feature where you can purchase the Free Spins Bonus feature for a lesser amount that than Buy Pass feature. Costing 50 x your total stake, the arrow needs to land in the green segment to get into the free spins. If it lands in the red segment, you return to the base game. The RTP if you do get in goes up to 96.86%. This feature isn’t available in the UK.

Bonus Bank feature

The Bonus Bank feature reduces the cost of entry to the Free Spins Bonus feature. You can opt for Bank Wins Off which adds all wins to your balance. If you select Bank All Wins, all wins are added to the Bonus Bank. You can also select Bank Small Wins which adds wins of 3 times your stake or less to the Bonus Bank. Like the above 2 features, it’s not available to UK players.

The gameplay in the Rainbow Riches Megaways slot here is pretty simple for a Megaways game. You’ll find the basic combination of cascading reels, mystery symbols and free spins with increasing multiplier which is on offer in plenty of other Megaways slots.

That combination has proved exceedingly popular and this game is no exception. The key to winning big is from the Unlimited Win Multiplier in the free spins. It’s not hugely original but if you enjoy slots in this Irish fortune-themed series, Rainbow Riches Megaways is a game to consider.

With 12,500 x bet max wins, it’s a lot more lucrative potentially than the original Rainbow Riches game which comes with 500 x stake top payouts. Yes, there are better Megaways games out there but it’s recommended if you’re a fan of the lucky leprechaun.

There are other slot developers that have made Megaways version of popular games. These include Gonzo’s Quest Megaways and Piggy Riches Megaways from NetEnt as well as Fluffy Favourites Megaways by Eyecon.
