Our guide begins long ago in the year 2008. I was much younger, attractive, and energetic back then… excuse me while I have a quick mental breakdown.

[15 minutes later]

In 2008, the online slot Rainbow Riches was released by Barcrest. At the time, this gaming company was one of the biggest in the industry. The Rainbow Riches slot was a success, not only in the online world of slot machines, but inside the land-based casinos, who at the time couldn’t foresee just how much the internet was going to screw them over. 

This disjointed guide is, however, a celebration of the Rainbow Riches slot series, and the rest of the guide will be covered by none other than the most famous Irish gambler of all, Leprecoin O’Spins. Me? I will be retreating to the darkest corners of my house, where I wish to remain until the sun swallows the earth, destroying us all. Good day.

Leprecoin O'Spins Lucknah-Lure Irish Slot Craicpert

“Wo’Hooo! Play this Irish spinning slot, or my fists will get red hot!”

Well, hellos to ya, ye fine lookin’ bunch. I’m Leprecoin O’Spins, some say the most psychotic gambler in all of Ireland. Whilst me own Ma’ will tells you I’m just a lad wit a lot of passion. I’m here to talk about the Rainbow Riches slots that make up this iconic Irish-themed series.

A Pot o’ Gold Overview: About the Rainbow Riches Series

The Rainbow Riches slot series is what happens when you take every Irish cliché, cram it into a leprechaun’s pocket, and hit spin. Developed by Barcrest (now part of Light & Wonder), this long-running franchise has become a staple of pub fruit machines and online casinos alike. The original Rainbow Riches launched in the mid-2000s and quickly spiraled into a full-blown saga with more sequels than sense, including Pick n’ Mix, Reels of Gold, Drops of Gold, Megaways, and Power Mix, just to name a few. 

What ties them all together? Pots of gold, rainbows, and the grinning little man in green who may or may not be mocking your bankroll. Whether you love them or merely tolerate them out of nostalgia, these games are unapologetically gaudy, mechanically simple, and somehow still charming in their own endearingly chaotic way.

You’ll learn everything from the Rainbow Riches free play demos that are available at Casinos.com to the real money slots online. I will also share with you the Best Rainbow Riches Slots of the bunch. 

The Lucky Favourites: The Most Popular Rainbow Riches Slots

Rainbow Riches

By today’s standards, the original 2008 Rainbow Riches slot doesn’t look much, but at the time, it gave players something new and different in its style and gaming dynamic. The features of the game were what made it a success. The Road to Riches, Wishing Well, and the Pots of Gold. Unique at the time, it offered players a medium to high volatility and a jackpot that would pay out 500x their bet.

Rainbow Riches Pick ’n’ Mix

The Rainbow Riches Pick ‘n’ Mix slot came with a more polished look to its design, more computerised than drawn. Still, the leprechaun remained ugly enough to give ye nightmares. The game was a level above the original and offered a bonus choice of five different bonuses. Road to Riches, Pots of Gold, Free Spins, Cash Crop, and Magic Toadstool. The volatility and the jackpot remained the same as the original game.

Rainbow Riches Megaways

As soon as Megaways became a trend, it was only a matter of time for Rainbow Riches to incorporate it, and they did so. The Rainbow Riches Megaways gave the game a bigger grid to play on. Between two and seven symbols could appear on a reel. It presented up to 117,649 ways to win, and it came with Cascading Reels. The game featured a Super Gem Bonus, Free Spins, an Unlimited Win Multiplier, and this time, players could win up to $250,000.

Rainbow Riches Reels of Gold

Reels of Gold was presented on colossal reels that held over one hundred paylines. It was a sight to behold. This was off-the-scale gaming, and well, you can see why it makes the list of best games in the series. This monster of a game came with a main reel and a colossal reel set, which provided ample ways of winning. Features included the Fairy Bonus, Free Spins, and the Balloon Bonus Pick, and load more, which yous will have to discover for yourself. But this game is, without a doubt, the biggest Rainbow Riches slot to date.

Rainbow Riches Leprechauns Gold

A more recent game in this series is the Leprechauns Gold slot. The gaming comes on a 5x7 layout, and presents fifty paylines, medium volatility, and a very high RTP at 97.75%. The features for this are the Lucky Leprechaun Bonus, Rainbow Ring Bonus Spinner, Wild Rover Bonus, Free Spins Bonus, and the Wishing Well Bonus. Also, keep yer eyes peeled for the Big Bet Game and the Super Rainbow feature. Another top game with a top prize payout of $250,000.

Jackpot Shenanigans: Rainbow Riches Jackpots

“Wo’Hooo! If jackpots ain't the prize, I’ll punch ye in your eyes!”

Due to the game’s popularity, it managed to make its way into a high-prized progressive jackpot series. When the standard fixed jackpot of $250,000 was suddenly ramped up to the millions. An example of this is the Rainbow Riches Jackpot King slot machine. The Jackpot King series is one of the largest progressive jackpots online. You don’t play this game for the Rainbow Riches free spins; you play to land the chance of winning one or more of the three jackpots. 

Progressive slots accumulate value in their prize pot, the more a game is played. However, it is also linked to other games in the jackpot series. This prize money grows until it is won, making the draw to such games the chance to win millions in real money.

Why Are Rainbow Riches Slots So Popular?

As you start playing these games you will immediately notice two things. The first is how easy it feels to play Rainbow Riches slots. The game mechanics are so simple, that it takes just a few moments to become familiar with the game. Next is the variety of bonus features and, in some cases, unusual layouts that make these games really stand out. While not all the games in the Rainbow Riches series have exceptional graphics, it is still easy to like them.

Rainbow Riches slots also capitalize on the Irish theme, using Irish folk tunes for soundtracks and featuring leprechauns, magic mushrooms and other common luck symbols from Irish lore that appeal to a significant percentage of players.

To keep the game fresh and engaging, the casino software developers working on the Rainbow series Riches has experimented with different mechanics over the years, introducing new releases like Rainbow Riches Power Mix and Rainbow Riches Cluster Magic.

Symbols in Rainbow Riches slots

Symbols of luck are at the heart of Rainbow Riches slots. These include: horseshoes, pots of gold, wishing wells, four-leaf clovers, rainbows, mushrooms, and let's not forget the lucky leprechaun. Some Rainbow Riches slots also feature standard card rank symbols like 10, Jack, Queen, King, and Ace as low-paying standard symbols.
