Theme, Audio + Symbols

The leprechauns are the stars of the show, and they bring with them lots of Irish references, including rainbows, Celtic patterns and, of course, those fabled pots of gold at the end of the rainbow.

Even though the game was created in 2009 it has aged well. Technology moves so fast nowadays, so the game looks vintage, but it still looks works.

The purple background is a great contrast against the white and gold-trimmed grid with Celtic symbols.

When triggering the Road to Riches bonus game, the scene changes to a gold-coloured road in the beautiful Irish countryside. You’ll see lush green grass, toadstools and farm animals. At the end of the golden road, you’ll see another rainbow with pots of gold to discover.

The higher-value reel symbols start with the Wild symbol, which is then followed by the Rainbow Riches logo symbol and the lower-value symbols of A, K, Q, J and 10.

Here are all of the values of all of the symbols you’ll find on the grid:

  • Wild symbol: 5 = 25, 4 = 10, 3 = 3, and 2 = 0.10. This symbol substitutes for all symbols except the Road to Riches, Wishing Well, and Pots of Gold symbols.
  • Rainbow Riches symbol: 5 = 12.50, 4 = 7.50, 3 = 2.50 and 2 = 0.10
  •  A and K: 5 = 7.50, 4 = 2.50 and 3 = 0.50
  • Q, J and 10: 5 = 5, 4 = 0.50 and 3 = 0.25
  • Road to Riches symbol: Landing 3 or more symbols triggers the Road to Riches bonus round.
  • Wishing Well symbol: Landing 3 or more symbols triggers the Wishing Well bonus round.
  • Pots of Gold symbol: Landing 3 or more symbols triggers the Pots of Gold bonus round.

Rainbow Riches Mobile

The game works well on mobile as it has been modernised with a sprinkle of HTML5 magic. This means you can be assured of a great gaming experience whether you're using a desktop, tablet, or smartphone. And the good news is that this applies to both iOS and Android models.

Bonus Features

Now, let’s look at the bonus features, which are one of the most important elements of any online slot experience.

Road to Riches Feature

Landing 3 or more Road to Riches symbols triggers this bonus round. The Roads to Riches feature involves a golden road, which you can see below. When you spin the wheel, it tells you how many steps you can take on this road to winnings. You spin the wheel a few times until you see the ‘Collect’ position, and you then collect your winnings. These winnings can be up to 500 x your bet. 

Wishing Well Feature

Landing 3 or more symbols triggers the Wishing Well bonus round. For this round, you simply need to click on any of the 3 Wishing Well symbols on the grid. This reveals a multiplier value. Here again, you can win up to 500 x your bet.

Pots of Gold Feature

If you land 3 or more Pots of Gold symbols, this bonus feature will be triggered. These symbols can land anywhere on reels 2, 3, or 4. You will spot bronze, silver, and gold pots spinning around on the screen. Once they stop moving, an arrow will select one pot, revealing a multiplier up to the value of, again, 500x your bet.

Look out for the Wild symbol, which is depicted by a Leprachaun on a gold coin. It substitutes all regular symbols apart from the Road to Riches, Wishing Well and Pots of Gold symbols. It’s also the highest-paying symbol on the grid paying out up to 25 x your bet.

Expert Verdict

Rainbow Riches slot OLBG rating banner

The Luck O The Irish theme is a tried-and-tested method nowadays. However, the Rainbow Riches slot was the first on the market and put these slots on the map. Yes, it does look dated, but that’s almost part of its vintage charm, and it speaks volumes that it’s still popular today. 

The features link well to the theme and are easy to follow. If you're a fan of multipliers, you’ll enjoy this game. However, there are no free spins bonus rounds, which the majority of online slot games include as standard nowadays. And with a 500 x max win and a 95% RTP rate it doesn't cut the mustard in the modern online slots world. 

But thankfully, Rainbow Riches has spawned a large amount of follow-up games. At the time of writing, there are 24 Rainbow Riches to choose from. In terms of RTP the highest is Rainbow Riches: Leprechaun's Gold at an impressive 97.75%. There are 11 games with a RTP of 96% or over, which is much more like it.

The highest max win is Rainbow Riches: Cash Cluster, at 12,500 x the bet. In fact, 5 of the Rainbow Riches games have a max win of 10,000 x or more. The majority of Rainbow Riches games have a medium volatility, although if high volatility games are more your thing, there are 4 to choose from. These are Rainbow Riches: Cluster Magic, Rainbow Riches: Race Day, Rainbow Riches: Power Pitch and Rainbow Riches: Crops of Cash.

I recently wrote an article comparing every Rainbow Riches slot game out there, which tells you everything you need to know.

Rainbow Riches is an iconic game and is fun to play however there are some great modern equivalents to enjoy which have better features and higher RTP and max win amounts.
