When it comes to online slots and bingo games in Ireland, few operators get close to Jumpman Gaming. It's a massive brand that spans multiple online casinos, including the colourful Rainbow Spins.

This bright and bold casino makes use of a theme often seen on Irish-themed slot machines, and that's just as well, as it's one of the most interesting casinos in Ireland right now. If you reside on the Emerald Isle, you're welcome to join this site and will be offered a sizeable welcome bonus when you do.

Usually, we make a point of saying that casino bonuses and promotions can change so should be checked before you play, but they usually stay the same at Jumpman Gaming sites. One of Rainbow Spins' welcome offers includes up to 500 free spins when you make a first deposit. The minimum deposit amount is €10. 

Just sign up, fund your account, open the Pot of Gold and you will win a random prize, which could be 500 free spins on Irish Pot Luck. But it could also be an Amazon voucher or various other prizes, so you'll have to try your luck.

You might be wondering what the incentive is to deposit more if everyone can win a 500 free spins bonus. Well, it all comes down to the following condition, one that is easy to miss: Max bonus conversion equal to lifetime deposits (up to €250). This means that the most money you can claim from bonus spins is equal to your deposit amount.

So, if you deposit €20 and claim the 500 free spins, the maximum you can claim once the 65x wagering requirements have been met is €20. If you deposit €100, that maximum increases to €100, and so on. The great thing about this Rainbow Spins casino bonus is that it appears time and time again as part of the loyalty scheme. You will be given a chance of opening more Pots of Gold when you advance through the levels at this new online casino in Ireland. 

By this point, however, you will have probably made more deposits, so the maximum payout amount will be higher. Remember, the 'max bonus conversion is equal to lifetime deposits'. This creates a rare but welcome scenario in which the casino's loyalty bonuses are more valuable than its welcome bonus. And, whether you agree this is an attractive bonus, it makes sense to reward loyal customers more generously than new players.

Some of the other terms you need to be aware of include:

• Wagering requirement of 65x (equating to €650 for a bonus payout of €10)
• Free spins are tied to specific games (often Fluffy Favourites and Starburst)
• Bonus funds can't be used to play progressive jackpot slots

The welcome bonus doesn't require a Rainbow Spins promo code but if you want the weekly More Free Spins bonus, for example, then you'll need to use online casino bonus codes - in this case the code is 'MORE'.

Live casino bonuses are not as common as slot offers but they do appear. These promotions usually give players a small sum of credits to spend on live casino games or invite them to participate in live casino tournaments. The bonuses and promotions section of the Rainbow Spins website will keep you informed about these offers.

Rainbow Spins has a few bingo offers. These change from time to time, but they include jackpots, free games, cheap tickets and special bingo events. You can also use some of the casino bonuses to play bingo games.

There are so many loyalty offers at Rainbow Spins Casino that it's hard to know where to start. There are free spin offers, vouchers awarded to the biggest winners of the month, Drops & Wins and more. The biggest loyalty promotion comes in the form of a trophy system. This system tasks players with completing challenges and gives them trophies when they do.

The rewards are also tied to a host of casino perks and when players advance through the levels, they will earn additional bonuses and free spin offers. As good as the welcome bonus is, it pales in comparison to the loyalty offers.

Rainbow Spins is as safe and secure as a casino can be. It holds licences from the authorities of the UK Gambling Commission and the Alderney Gambling Control Commission, uses an advanced SSL and is part of a vast network.

It also works with developers certified as fair and provides players with a number of secure payment methods, including Visa, Mastercard and PayPal. If you're worried about your gambling habits, there are problem gambling resources and tools, such as deposit limits and self-exclusion.

Once you sign up for a Rainbow Spins account, you will be taken to a vast casino game room with stacks of live casino titles, slot machines, jackpot games and bingo rooms. There are hundreds of casino games from the likes of Playtech, NetEnt, Blueprint Gaming and Play'n GO.

The table game selection on Rainbow Spins isn't the biggest or best, but its bingo rooms more than make up for it. These games invite you into the Jumpman Gaming Limited network, where hundreds of players compete for prizes in the tens of thousands. Some games even offer 6-figure sums.

These bingo titles include Boombox 80-Ball Bingo, 90-Ball Heavyweight and 75-Ball Country Road, to name just a few. Tickets are available for as little as €0.01, and there are many prizes on offer. Every now and then, Rainbow Spins hosts games with mind-blowing jackpot sums, so keep an eye out for these. If you're looking for more traditional table games, there are a dozen or so of these titles to choose from, including:

• Vegas Strip Blackjack
• Atlantic City Blackjack
• Australian Roulette
• Roulette x2
• Vegas Downtown Blackjack
• Casino Solitaire
• 100/1 Roulette

Rainbow Spins has hundreds of real money slot machines, including some of the most popular titles in the United Kingdom and Ireland. You can take your pick from classic video slots, 3D slots, bonus slots, and other games with features such as Cascading Reels, Link and Win and Megaways.

Unsurprisingly, Rainbow Spins is also home to Rainbow Riches, a massively popular slot game that was created by Barcrest Gaming and is now part of Scientific Games. Rainbow Spins was no doubt influenced by this slot, and as it's a player favourite, it's a welcome addition to the games room. Fluffy Favourites and Starburst are also available. These two popular NetEnt titles often feature in the site's many Free Spin bonuses, so you will get plenty of chances to play them.

• Eye of Horus
• Solar Temple
• 9 Masks of Fire
• Big Bass Splash
• Monopoly Mega Match
• 4 Fantastic Fish
• Sonic Links
• Mustang Gold
• Chilli Heat
• Fishin' Frenzy
• Blue Wizard

Rainbow Spins has a small selection of live casino games provided by big-name developers. There are variations of poker, blackjack, baccarat, roulette and more, as well as game show titles. You won't see these games listed under the main Rainbow Spins website, but they will be revealed when you join. 

Rainbow Spins live casino games are available around the clock and you don't need to worry about long queues. As noted above, you can even pick up a live casino bonus or two to play them with.

Rainbows, pots of gold and leprechauns - these themes are commonplace throughout the online gambling sector. They are usually left for online slots, but with Rainbow Spins, there's no getting away from them! This casino takes the "Lucky Irish" theme and goes all-out, adding splashes of colour, style and frivolity to its reels.

But it's not all style and no substance (or, as the Irish might say, all short and no trousers). In addition to this welcoming theme and the promise that all Jumpman Gaming casinos provide, Rainbow Spins offers a multitude of slot machines, bingo games and live casino games. The icing on this delicious casino cake is the casino's abundance of bonuses, including ones targeted toward its slots and live casino games, as well as its bingo titles.

There are a few downsides, including the fact that all online casino withdrawals incur a €2.50 charge, and the site is very similar to other Jumpman casinos, but these are minor in the grand scheme of things. Check out Rainbow Spins today to see all of these colourful features for yourself.
