Best Rainbow Riches Sites UK - Free Spins & Offers - February 2026

The leprechaun themed slot game is an all-time favourite. It has been around for a long time, but throughout that time, its popularity has endured. It’s like Ashton Kutcher—it crops up everywhere and never ages.

Even in an era where modern, cutting edge slot games are being released, this golden oldie remains in the top tier of every casinos slot collections, fighting off new releases—it is, it seems, timeless!

Why is Rainbow Riches So Popular?

There are a few popular themes for online slots with fluffy toys and candy symbols rising to the top of the list.  However, there is one theme that stands heads and shoulders above the rest, this is the “anything Irish” theme.

I have been writing about slot games for many years, and throughout that time I have seen, played, and reviewed countless Irish-themed slots. It’s a combination that never seems to fail, even though it has been done to death.

The above seems to be about right. However, certain game developers have done better than others, with Barcrest, the original creator of Rainbow Riches, being one of the clear winners.

The Irish theme is knee-deep in Irish cultural connotations of luck.

In that particular area, without thinking too hard, you’ll realise that there’s plenty for an eager games developer to go at. Pots of gold can be located with the help of rainbows, cheeky Leprechauns, Clovers, and so many other things. For slot creators (and bar owners around the globe), Ireland seems to be the well that never runs dry.

Grabbing the Irish theme with both hands, Barcrest undoubtedly understood that they were onto a big hit with Rainbow Riches back in 2006. Not ones to look a gift horse in the mouth, this developer continued to churn out top titles, and many of those have carried the Rainbow Riches name.

Bonus Features, as I will explain further down, has no doubt contributed to the success of the series too.

The Barcrest Story

I said that Barcrest were the original creators of Rainbow Riches, and while you’ll still see this developer’s logo on Rainbow Riches slot, the backstory gets quite complicated.

Barcrest is a British company that made its name making physical slot and gaming cabinets, which is why Rainbow Riches machines have been commonplace in arcades and casinos across the UK for so long.

In 1998, the brand was acquired by IGT, an iGaming powerhouse responsible for many other great games, and one that made its own contribution to the land-based sector. In 2010, it was acquired by Scientific Games, which then became Light & Wonder.

It’s been quite a journey, but throughout that time, Rainbow Riches has been one of Barcrest’s most prized assets, making the company a valuable commodity among the many Light & Wonder subsidiaries.

What are the Main Bonus Features of Rainbow Riches?

Launched back in the days when slot games had very few features, Rainbow Riches caught a lot of attention by coming to the market with three spectacular bonus features.

The list below contains probably the three most famous bonus features of any slot game ever released!

Wishing Well

Kicking the list off with the best known of the lot, Wishing Well is probably the bonus feature you’re most likely to see when playing Rainbow Riches. The feature is triggered whenever three or more of the Wishing Well symbols appear anywhere on the reels.

The Wishing Well feature grabs the attention of the players from the offset by inviting them to “choose” one of the wishing wells. Of course, as with many choices you’ll be asked to make when playing slot games, the outcome is entirely down to chance and your input makes not a jot of difference.

Once you’ve made your selection, the random number generator will do its thing, and the outcome will be a random multiplier that will be assigned to your wager and added to your balance! Depending on your wager and the multiplier assigned, this can make for a very lucrative bonus round.

If you’re lucky enough to land four or five Wishing Wells, the outcome will be as above,  but the multipliers are significantly higher.

Road to Riches

Road to Riches was born as a feature in the original Rainbow Riches slot game, but in an attempt to piggyback on their own success (as they’re quite entitled to do), Barcrest have since released a slot game of the same title.

Players tend to seek out Road to Riches more than the other two features, probably because it’s by far the most interesting, even though it’s technically not the biggest of the three.

I know, as I used to do exactly the same. I thought this was the game’s biggest feature and constantly sought it out. So much so, in fact, that I was a little disappointed when I unlocked another feature. That disappointment didn’t last, though, as discussed below.

Road to Riches is triggered in the event that a player is lucky enough to land a minimum of three of the Leprechaun Scatter symbols. As with Wishing Well, four or five of these symbols will further increase the payout potential.

Once the round has been triggered, it’s time to follow the yellow brick road, a winding path filled with multipliers. Players are asked to spin a wheel, the purpose of which is to decide (at random) the number of steps the player will advance along the road. As the path continues, the multipliers get larger, so players will hope the wheel stops on a high number. The spinner also features a “Collect” segment, which immediately brings the round to an end.

Pots of Gold

This is the feature that initially disappointed me, but it’s one that I have been chasing ever since.

In the event that you trigger this feature by landing the Pots of Gold symbol a minimum of three times, a prize wheel will be launched. The wheel contains some huge multiplies, which, depending on your wager, could equate to a sizeable win!

The first time I did this, I walked away with a 200x win. It was the biggest payout I had received at that point, and while I stupidly lost half of that money in a resulting gaming session (one where I chased the Pots of Gold feature and wasn’t even compensated with Road to Riches), it still makes for one of my most memorable slots experiences.

Just as they did with the Road to Riches feature, Barcrest have released a slot game titled Pots of Gold. Again, it’s the gift that keeps on giving.

Best Rainbow Riches Sites

Rainbow Riches will be the same wherever you play it. Unless you’re playing a unique variation of the game, one that you can’t find on another site, everything from the theme, style, payouts, and features will be the same from one casino to the next.

It’s not the game itself that defines the “best Rainbow Riches sites”, but the bonuses that are attached to it. If you pick up a 100 free spins bonus, for instance, and those spins are tied to this game, it may be worth more to you than a 20 free spin bonus on a game like Starburst, especially if you’re not much of a fan of this NetEnt title.

I have created a Rainbow Riches table to show just how many games there are in this series and also to signpost you towards a range of sites that offer them.

Top tip: Rainbow Riches fans should check out the aptly titled Rainbow Riches Casino site from Gamesys.

Freeplay Rainbow Riches

Bingo Paradise operates within the UK. As such, it is unable to host a free-play version of Rainbow Riches. However, from time to time, I see sites that offer Rainbow Riches free spins with no deposit.

I recommend you try Rainbow Riches at one of the destinations I have listed in the above table. Whilst it may not be possible to play without spending money, there are offers which will give you ‘free’ spins on other slot titles upon an initial deposit of £10. These offers may represent a good value way of testing the game (plus, unlike in free-play versions, if you win, you benefit).

If you’re yearning for some free spins or bonus spins on card registration (not on Rainbow Riches), there is a page for that.
