Rainbow Riches Fortune Favours is a magic fairy Celtic-themed slot and a popular entry in the long-running franchise. Developed by Barcrest, this particular Rainbow Riches slot game keeps things classic. It also has a big bet option, which unlocks extra reel sets. With up to 4 available in play, I was eager to see the slot in action close by.

The medium variance slot has an RTP of up to 97.75%. Reaching those high values requires activating the Big Bet. It has 10 fixed paylines and aesthetics that match the rest of the series. In terms of special features, it has a wild and a magic fairy bonus symbol, which transforms others into random matching symbols. Multiple fairies can land on the reels simultaneously, greatly increasing the winning potential.

Rainbow Riches Fortune Favours follows a mostly traditional math model with a base game and a bonus spins round. Similar to other entries in the series, the best features are only unlocked with the Big Bet option. It costs a lot, but with the possibility to play on 4 sets rather than just 1, this is something you ought to try. Read my Rainbow Riches Fortune Favours slot review below to learn how it all works.

The look and feel of the Rainbow Riches Fortune Favours slot is vintage and Celtic in style. There’s no question that this is an Irish-themed slot when you take a look at the splash screen, which pairs the fairy with a leprechaun. It also has that vintage RR visual design. You’ll see the same symbol designs across all the slots in the series, and once again, the slot is set against a green meadow with a rainbow behind it.

This time, the rainbow is not part of the gameplay, nor is the leprechaun. The slot’s clean design, with the reel set in the central column and controls beneath the reels, makes it very easy to play on any device. In terms of symbols, you’ll see mushrooms, a fairy, a rainbow, the Rainbow Riches logo, and a hard – all Celtic-themed symbols. The great graphics are accompanied by a Celtic tune, which perfectly fits the theme.

Place a bet between 10c and $500 per spin and hit the spin button to start playing Rainbow Riches Fortune Favours. The math model is straightforward, so you need 3 or more matching symbols on one of the 10 paylines to score a win. The Rainbow Riches logo is the highest-paying symbol, delivering wins of 2,500x for five. While most Rainbow Riches real money casino slots feature a classic wild, here, it’s only available via the 30x+ Big Bet option.

To make things more exciting in the base game, the slot has introduced a magic fairy symbol. It’s active on all stakes. Whenever it appears, it magically transforms one random symbol into a random mystery symbol. Several fairies can land on the reels at the same time, transforming multiple symbols into random ones. This can lead to some decent wins from the get-go.

There are no other special features unless you pay for the Big Bet feature. I’ll cover more of it below.

The Rainbow Riches Fortune Favours slot game’s Big Bet option is mostly similar to a bonus buy feature. There are 5 tiers for it, and the more you pay, the more specials you unlock.

• At the first level, which costs 10x, you get the magical fairy active at all times.
• Pay 20x, and every magic fairy in sight is copied to an extra 5x3 reel set.
• For 30x, you get the magic fairy, a standard wild symbol, and any fairies transferred to other reel sets.
• If you pay 40x, you get 4 reel sets with magic fairies and wilds.
• At the maximum of 50x, you get all the aforementioned specials, plus 10, J, and Q removed from the reels.

While there’s no bonus spins round, the Big Bet can deliver pretty decent wins. It will cost you more than usual, but you get greater winning potential and special features enabled.

My experience with the Rainbow Riches Fortune Favours slot was positive overall. The base game itself didn’t produce many surprises, so after around 20 spins at a bet of $1, I switched to the Big Bet option. Initially, I bet 30x but eventually ended up paying the max. I have to say that it wasn’t as fruitful as I had hoped, but I did hit several big wins across the 4 reel sets.

At the maximum level, the slot removed a few low-paying symbols and added a wild in addition to the fairy. I played across 4 reel sets instead of one, and I can say that it’s much more exciting than playing on 1. Overall, the slot has decent winning potential, but you’ll have to pay extra if you want all the features to be active.

At a bet of $2, the Rainbow Riches Fortune Favours slot RTP is 94%. Use the Big Bet, and it can shoot up to 96% at bets over $2 per spin or up to 97.75% on the highest Big Bet tier. Any combination of wins can’t exceed $250,000.

Rainbow Riches Fortune Favours sticks to mostly vintage gameplay, with a few specials activated by the Big Bet option. While some players won’t like the fact they need to pay extra, it’s a feature you’ll find in other slots in the series, too. It costs a lot more, but for the features you get, it’s more than worth it.

If you prefer another slot in the long-running series, go for the original Rainbow Riches. It’s the slot that started it all and one of the classics that never go out of style.
