The Rainbow Riches slot was designed and developed by Barcrest and powered by SG Digital (Light & Wonder) and WMS. It’s the first title in the popular series with the same name.

5 reels featuring 3 rows and 20 adjustable paylines are available to all players in this slot. This is more or less a standard gameboard in today’s games. Also, the visuals are a bit retro since it’s a slightly older title. Still, they do well thanks to their attractive colors and unique details. The audio also has a vintage vibe.

Let’s note that the Rainbow Riches slot has an RTP of 95%, making it an average game. Besides that, players can expect a medium volatility release. Players can activate one of the three special features by hitting specific symbol combos.

Even years after its premiere, the Rainbow Riches online slot is still popular among players. You should read our unbiased Rainbow Riches slot review to see what makes this title stand out. Those interested in other titles can check the best online slots we reviewed and shared on our platform.

Game Data

It turns out that following the Leprechaun is a wonderful idea. The Rainbow Riches slot game is an Irish-themed title where a leprechaun is a central star. This game by Barcrest is the first in the series, including over ten other titles.

If you have played one of them, you will probably recognize the distinctive graphics and sound effects of the rest. The Rainbow Riches was released in 2009, but it includes everything you need as a modern player, like stake adjustment, adjustable paylines, an auto-play feature with advanced options, sound control, etc. Activating one of the several bonus features will spice up your gaming experience.

We suggest checking our detailed review below to get additional information about the Rainbow Riches slot.

Graphics, Music, and Sound Effects

The visual aspect of the Rainbow Riches slot is not its strongest selling point, and this makes sense because the game was released years ago. Still, this doesn’t mean you can’t find some interesting elements.

For instance, we have a beautiful gold frame with Celtic motifs around white reels. The icons are colorful and include fun details. On top of that, there’s a background image, primarily violet, depicting a meadow and a rainbow.

The only music you can hear is during the spins and after hitting winning combinations. It sounds like a lyre. As for the sound effects, they’ll probably remind you of older slots.

Key Features

Don’t let the average audiovisual side of the Rainbow Riches online slot disappoint you. As we said, this is not something where this game excels at. Of course, the situation will be different once you discover its main features.

The evergreen theme, the RTP, the bet range, and bonus features are some things we will discuss in this Rainbow Riches slot review.

We use an identical approach in all our slot game reviews since we know it helps players select the suitable game for their needs.

Theme – Irish

Players with some experience in this area have probably tried at least a few titles inspired by Irish myths and legends. With the Rainbow Riches slot, we are (once again) sent to Emerald Island, where the magic happens on the other side of the rainbow.

The Rainbow Riches story involves a leprechaun and pots of gold, among other things. It’s a timeless Irish story with exciting twists.

This story is portrayed well through the game’s icons. In addition to the five playing card values with Irish ornaments and the game’s logo, you will find a Gold Coin, a Leprechaun, a Wishing Well, and a Pot of Gold in the role of symbols with unique properties.


5 reels and 3 rows per reel are available in this game by Barcrest. Together, they create a 5x3 gameboard, probably the most used combination in online slots.


Like the reels and rows, the number of paylines in the Rainbow Riches online slot is standard. So, we have a game with 20 paylines. Still, we should mention that the number of paylines is adjustable, and you can play with as little as just 1 active payline.

Regardless of your option, three to five regular symbols of the same type on an active payline are needed for a winning pattern.

The theoretical RTP (Return to Player) percentage is next on the list of key game features. Although it’s hypothetical, it’s an important figure that reveals how much players can get after some period playing this game. As for the Rainbow Riches RTP, it’s an average value of 95%.

Remember that online casinos are allowed to alter the percentages. We created a table to help you find the best casinos with this game and learn about the exact RTP % on these sites.

Other things besides the RTP can help users find the best option to play this game at a casino site. These factors include the casino's welcome bonuses and deals, security and licensing, game variety, payment options, customer care, etc.

The slot sites we recommend are on a separate page where we have compiled a list of the best UK casinos for slot players. If you are in the UK and you love slots, it would be wise to open this page.

Stake Range

Since the paylines of the Rainbow Riches online slot are adjustable, the stakes can come in different sizes. So, there’s a wide stake range here, starting with £0.2 and ending with £500 per spin when you use the default number of paylines – 20.

When changing the bet, you select the value of a line bet - £0.01 to £25, but the total bet value adjusts automatically.

Max Win

The maximum win at the Rainbow Riches slot is capped at 500x the stake. This may look low to some players, but let’s not forget that the maximum bet is £500.

Road to Riches Feature

The Leprechaun is one of the four Scatter icons. When players have three or more Leprechauns on the reels, they will activate the Road to Riches feature. This game lets you spin the wheel to get a specific number of steps on the cash path.

This feature ends when you land on the collect position or reach the final prize. The rewards here promise 1x to 500x the total stake.

Wishing Well Feature

Next on the list, we have the Wishing Well Scatter symbol. You will activate the Wishing Well feature whenever you land three or more Wishing Wells anywhere on the matrix. Your job is to clock on a Wishing Well to reveal a multiplier value. Simply put, you can uncover a multiplier worth 2x to 500x, which will be applied to your total stake.

Pots of Gold Feature

When you hit three scattered Pots of Gold anywhere on reels 2, 3, or 4, the Pots of Gold feature will be activated. Once launched, you will spot bronze, silver, and gold pots spinning around the main screen. Once they stop moving, an arrow will select one pot, revealing a multiplier value of 50x to 500x applied to the stake.

Remember that the Leprechaun Gold Coin is a Wild icon that substitutes all regular symbols in situations where it helps users finish winning patterns. Also, this is the highest-paying icon promising 0.1 to 25 times your stake for 2 to 5 Wilds on a payline, appearing only in the base game.


Let’s get straight to the point – the Rainbow Riches slot has no direct jackpot prize. Players who want to play for this specific prize can use our page with the best jackpot slot games.

Play Experience & First Impressions

It was not just the luck of the Irish that was put to the test here. This 100-spin test of the Rainbow Riches slot helped me realize how lucky I am. It’s not common to end a round like this with an almost equal balance as the one you started with.

So, I had an RTP of 101.5% at the end of this session, which is a good thing. I was lucky to activate one of the bonus features – the Wishing Well Feature – on the 12th spin. This bonus round brought 15 times my total stake.

Still, I ended with a rare experience where the biggest base game win was much higher than the bonus game win. I am talking about a win worth 35 times my bet achieved with the help of multiple combos with the game’s logo.

The overall experience I had with the Rainbow Riches is positive. I like how the game provided substantial wins of 5 or more times the base bet from time to time. Also, the sound effects might be retro, but they were entertaining.

100 Spin Test

100 spins test Slot review

100 spins is not a Real Test

We give every slot a 100 spin test to see just what it can do, or not as the case can often be - 100 spins is no reflection of the likelihood of any other 100-spin session, as RTP's are set over many millions and probably billions of spins. So this 100 spin test is just for entertainment and insight purposes

Expert Verdict

Fans of Irish-themed slots packed with gold, ornaments, and leprechauns have an opportunity to try the Rainbow Riches slot game. This release by Barcrest, powered by WMS and SG Digital (Light & Wonder), is one of the games that made this theme popular among online slot players.

This was the first title of a successful series played in many online casinos today. So, it’s logical to expect entertaining moments from a game that has been active for such a long time.

The Rainbow Riches slot has an RTP of 95%, which I exceeded with my test spins. It’s also a medium-volatility product which is another thing I witnessed firsthand.

Regarding graphics and music, you should not expect too much from a game released in 2009. Still, we definitely can’t say that it’s outdated. A round of free spins, almost a standard bonus feature today, is not present in this slot. However, you can activate three fun and potentially lucrative mini-games.

Without the bonuses, Rainbow Riches might be a release that would have been forgotten. Still, the extras, evergreen story, and other things make it a good choice even today.
