Rainbow Riches Casino offers some of the most attractive online casino offers in the UK, including two welcome offers, one for bingo and one for casino. To claim either of the welcome bonuses, you'll need to deposit at least £10 and wager at least £10 on any games. What's more, you'll need to complete all wagering requirements within 30 days. There's no bonus code needed and your offer will be applied automatically once you opt in.

The online casino bonus allows you to claim a bundle of slots free spins on the original Rainbow Riches slot once you've deposited and wagered at least £10. 

The great news is that any winnings from the bonus spins are paid out in cash, with no wagering requirements to worry about. This is a huge plus and isn't something that you often see at the best UK casino sites.

There are also chances to win your share of huge amounts of free spins, there are regular giveaways where you can win cash, plus if you follow the social media channels there are even more special offers over there.

Unfortunately at present Rainbow Riches Casino doesn't offer a special welcome bonus for live casino players, and as the main casino bonus just consists of free spins, it's not much use to live casino players unless you win some extra funds with the free spins. However, there are other regular promotions like the chance to win cash prizes when you wager.

There's no sports betting element to the Rainbow Riches Casino experience, so you won't find any sports bonuses here.

It's great to see that Rainbow Riches casino offers a special welcome bonus for bingo players. You'll get free bingo tickets up to a maximum value of £50 and with a minimum value of 50p, and these can be used on any bingo game on the site, with the exception of Session Bingo.

Rather than a traditional loyalty programme, Rainbow Riches has the PLUS Scheme. You're rewarded on loyalty and your engagement as a player, including participation in games and promotions. This is done on a relatively ad-hoc basis and the team will be in touch and let you know if you qualify for a special reward, like a casino bonus or some free spins.

Rainbow Riches Casino is operated by a company called Gamesys, and is regulated in the UK by the Gambling Commission, under the account number 38905.

Here there's even a handy video to explain the tools and features available to you - you can set deposit limits or session time reminders, take a time-out for up to six weeks, or self-exclude to block access to your account.

We were very impressed with the selection of table games available at Rainbow Riches Casino, particularly their roulette offering. There are some very special variations available, like Phoenix Roulette and Signature Roulette, plus there are a few blackjack options like Multihand Blackjack to keep up with the top online blackjack sites. Poker is big too, with the option to play either in a live dealer environment or in a unique way with the chat hosts. You can also play baccarat at this online casino with several game options to pick from. 

There's no shortage of video slots at Rainbow Riches Casino. You'll really channel the luck of the Irish when you explore the "Leprechaun's Choice" section, which is brimming with lots of variations of the much-loved Rainbow Riches slot game.

This definitely isn't all there is to the online slot selection though - whether you're looking for a classic, popular slot game (Wolf Gold, Fishin' Frenzy), top Megaways slots (Buffalo Rising Megaways, Bonanza Megaways), or one of the huge jackpot slots, you're very well catered for here.

There's a great selection of live casino games available at Rainbow Riches, coming from top providers like Evolution Gaming. There are numerous VIP table available and the stakes range from just 20c, all the way up to thousands of euro per go, depending on the casino game and the table. , The main games that Rainbow Riches Casino focuses on are roulette, poker, and live blackjack in the UK. 

Choose from the likes of Lightning Roulette and Instant Roulette, have a go at Free Bet Blackjack, or try your hand at Caribbean Stud Poker. There are also some "signature" options which are only available at Rainbow Riches Casino and its sister sites, making this one of the more unusual live casinos in the United Kingdom.

Rainbow Riches Casino is definitely somewhat of a novelty, being mainly based around the popular Rainbow Riches slot machine. Aside from the visuals, though, the overall experience is pretty simple and straightforward, and places a lot of focus on the quality of the casino games. There are lots of promotions, but they have avoided the complex customer journeys and multi-layered loyalty schemes that may overcomplicate the player experience at a lot of other online casinos.

If you're a mobile player, you'll be glad to know that Rainbow Riches Casino does have a mobile app, available for both iOS and Android. It compares well with other casino apps and you can play all of your favourite games including slots, table games and bingo using it. Many will find it convenient that you don't need to open up your browser, search and log in every time you want to play.

Deposits and withdrawals are also straightforward. The range of payment methods isn't the biggest, but you can use your bank card or Apple Pay (on supporting devices), and the maximum deposit amount is high, at £20,000 per transaction for bank cards. You can use the same methods for withdrawing and funds usually take a few days to reach your account.

Many of the games at Rainbow Riches Casino come from the provider Barcrest (this makes sense as they're the brains behind the Rainbow Riches slot game), but there's also a good selection of games from other major providers like NetEnt, Evolution Gaming and Pragmatic Play. It's not the biggest selection of providers, but the ones that the casino does offer are all very high quality.

Overall, we'd definitely recommend giving Rainbow Riches Casino a try. You simply can't go wrong with the fun Irish theme, the good slots and table game variety, and the exciting promotions! So if you're looking for gambling sites with free spins, you could do a lot worse than checking out Rainbow Riches Casino.
