Types of St. Patrick’s Day Bonuses Offered at UK Online Casinos
UK players can claim a wide range of St. Patrick’s Day casino promotions. We explore all the different types below.
Free Spins
Free spins are among the most common St. Patrick’s Day Casino bonuses. These will be available on Irish-themed slots like Rainbow Riches, Irish Luck and Lucky Leprechaun.
At our recommended sites, you’ll find a huge range of St Patrick’s Day free spins offers. Some will have set cash values, such as £10 in free spins, whereas others can be used across slots made by a certain software provider.
These festive slots will not only lighten your spirit but also maximise your winnings, adding an extra layer of luck to your St. Patrick’s Day celebrations.
No Deposit Bonuses
Easily one of the best St. Patrick’s Day Casino offers is the coveted no-deposit bonus. All UK players need to do is open an account and verify their identity. From there, you’ll be rewarded with a bonus. This can be anything from free spins to a free bet.
No deposit bonuses are exactly what they say they are! This means you are not required to deposit any of your own money to wager on casino games. Nevertheless, the bonus credits may only be able to be used on a specified game. This is often an online slot, but it will be Irish-related because of St Patrick’s Day.
Welcome Bonus
During the build-up to St. Patrick’s Day, UK players will be able to claim a special welcome bonus. This could be a no-deposit bonus, free spins or a matched bonus. Many times it’s a combination of a matched bonus and free spins on an Irish slot game.
As it’s a special day, online casinos go the extra mile to attract new players. Therefore, expect St. Patrick’s Day casino bonuses to be much better than an average welcome package. That means wagering requirements will be lower, and the amount you can claim will be much higher.
No/Low Wagering Bonus
We think one of the best St. Patrick’s Day casino offers are ones with extremely low or even no wagering requirements. With most casino bonuses, you are required to wager the funds a certain number of times before you can withdraw. The industry standard is 30 – 35x.
However, on St. Patrick’s Day, online casinos will offer UK players promotions with no wagering requirements. That means whatever you’re winning is yours to keep! You’ll also find bonuses with wagering requirements of less than 10x. This makes it much easier for you to cash out if you win!
Cashback Bonuses
St. Patrick’s Day cashback bonuses give UK players a percentage back of their losses over a period of time. This is most often during the week of March 17th, and in our time, we’ve seen cashback offers all the way up to 25%!
Cashback offers are a terrific way for online casinos to reward loyal players, especially on holidays such as St. Patrick’s Day. Claiming a cashback offer is simple; it will normally be automatic. For example, if an offer is 10% cashback and you bet £100 in the last week, expect £10 to be credited to your account.
VIP Deals
Online casinos look after their VIP players very well. If you wager big sums of cash, expect to receive special treatment on St. Patrick’s Day.
When you are a VIP you’ll get a personal account manager, faster withdrawals and high limits. Not to mention tailored bonuses. VIP players can expect the best casino St. Patrick’s Day offers, such as no deposit bonuses, free spins and cashback offers.
Tournaments
On March 17th, be on the lookout for plenty of St. Patrick’s Day casino tournaments. These can either be slots or table games tournaments, and the aim is to win as many points as possible. The more points you get, the higher you’ll finish on the leaderboard.
After the tournament, players at the top of the leaderboard will be rewarded with prizes. Expect the top 10 to get big cash prizes, whereas if you finish in the top 50, you might get a no-deposit bonus or free spins.
