Rainbow Riches has been part of the UK slots scene for years, and its simple setup is probably one reason it has lasted so long. There are no changing reel sizes or complicated collections to keep track of. Instead, the game uses five reels, three rows and 20 fixed paylines, with three separate bonus rounds sitting at the heart of the action.
The theme will feel familiar even to anyone playing it for the first time. A rainbow stretches behind the reels, Irish-style music plays in the background and symbols such as leprechauns, wishing wells and pots of gold appear alongside the usual card values.
Barcrest created the original Rainbow Riches game. Since then, the name has grown into a wider series that includes Megaways, Slingo and feature-led versions, but this is the straightforward original.
Every spin uses all 20 paylines. Choose a stake from the options shown inside the game, press Spin and wait for the five reels to stop.
Most wins need three or more matching symbols to land from left to right across the same payline. The Rainbow Riches logo and Gold Coin can also form combinations with fewer matching symbols.
The lower part of the paytable contains the 10, Jack, Queen, King and Ace. The Rainbow Riches logo sits above those card symbols, while the Gold Coin acts as the Wild.
A Wild can replace the regular paying symbols when that substitution creates or improves a winning line. It cannot replace the Leprechaun, Wishing Well or Pot of Gold symbols because those have a separate job: they trigger the bonus games.
Check the live paytable before playing for the current symbol values. Older Rainbow Riches reviews sometimes show payouts as line-bet multiples, while others compare them with the full spin value. That can make the same combination look different from one website to another.
The stake amounts shown in older reviews can also be misleading. Use the options available inside Heart Bingo rather than relying on historic maximum-stake figures.
The regular symbols are deliberately straightforward.
The 10, Jack, Queen, King and Ace make up the lower-value part of the paytable. Above those sit the Rainbow Riches logo and the Gold Coin.
Three further symbols trigger the bonus rounds:
These trigger symbols do not need to form a normal left-to-right payline win.
The Gold Coin works as the Wild symbol.
It can replace the regular card symbols and the Rainbow Riches logo when doing so helps create a winning payline. It cannot stand in for the Leprechaun, Wishing Well or Pot of Gold bonus symbols.
The Gold Coin can also form its own matching combination.
The Rainbow Riches logo is the strongest standard symbol below the Wild.
Unlike the card symbols, it can produce a win from two matching icons. Three, four or five logos increase the value of the combination.
The original game does not have a standard free spins round. It offers Road to Riches, Wishing Well and Pots of Gold instead.
Each feature has its own trigger and plays out differently.
Land three or more Leprechaun symbols to open Road to Riches.
The reels give way to a winding trail with different prize values placed along it. A wheel controls how far the character travels on each turn.
The feature continues until the wheel lands on Collect or reaches the final point on the trail. More Leprechaun symbols may provide a stronger starting position, although the current rules inside the game should be checked for the exact setup.
Road to Riches takes longer to unfold than the other two bonuses. The final result does not appear immediately, so there is a little more suspense as the character moves along the path.
Three or more Wishing Well symbols trigger this feature.
Several wells appear on the screen and you choose one. The selected well then reveals the result.
That is the whole round. There are no additional stages or free spins afterwards, which makes Wishing Well the quickest and simplest feature in the original Rainbow Riches.
The correct name is Wishing Well, not Wishing Wheel.
The Pots of Gold symbols appear on the three middle reels. Landing one on reels two, three and four activates the bonus.
Bronze, silver and gold pots begin moving around the screen. Once they stop, an arrow points towards one and reveals the result hidden behind it.
Unlike Wishing Well, there is no player selection here. The game chooses the final pot automatically.
Pots of Gold became one of the best-known features in the Rainbow Riches series, and several later games have built on the same idea.
Rainbow Riches is available through Heart Bingo on supported smartphones and tablets.
The mobile version keeps the same five reels, 20 paylines and three bonus games. The controls move around the screen to fit the smaller display, but the rules do not change.
Open Heart Bingo through a supported browser or app, sign into your account and search for Rainbow Riches. A stable connection will help the reels and bonus animations run smoothly.
The original game is the simplest member of the series, but there are several alternatives at Heart Bingo.
Rainbow Riches Megaways changes the entire reel structure. Instead of 20 fixed paylines, the number of symbols on each reel can change between spins, creating up to 117,649 ways to win. It also adds cascading combinations and a free spins feature.
Rainbow Riches Pick N Mix takes a different approach by letting you choose from several bonus features. Road to Riches and Pots of Gold return, alongside options such as Cash Crop and Magic Toadstool.
Slingo Rainbow Riches is not a traditional five-reel slot. It combines numbered Slingo cards with symbols and features inspired by Rainbow Riches.
Players who prefer the familiar Irish theme but want a different game can also try 9 Pots of Gold.
More titles can be found in the Heart Bingo online slots section.
Rainbow Riches feels more traditional than many modern online slots. The grid stays the same on every spin, there are no long collection features, and each bonus is easy to recognise.
That simplicity will suit some players more than others. Road to Riches offers the longest feature, Wishing Well gives a quick pick-and-reveal result, and Pots of Gold uses a short animated selection.
Before playing, open the paytable and read the current feature rules. Choose a stake that fits the spending limit set for the session.
Every spin has a random outcome. A run without a bonus does not make one more likely to appear on the next round.
