Most Popular Kind of St. Patrick’s Day Promotions 

St. Patrick’s Day offers come in all shapes and sizes, although one has to point out that St. Patrick’s Day free spins are the most common of these bonuses. That said, new players will also find attractive welcome bonuses, while existing customers should look out for no deposit bonuses. 

St. Patrick’s Day Free Spins

Nothing compares to free spins when it comes to St. Patrick’s Day offers. These remain the absolute favourites among UK online casino players for good reason, as they are a great way of checking new online slots and casinos… for all but free! The amount of St. Patrick’s Day free spins available varies from one operator or another, but usually ranges from 10 to 50 free spins. That said, sometimes you might manage to get your hands on even more! 

St. Patrick’s Day Welcome Bonus

Casinos are always on the lookout for new players, while the holidays make for a good excuse to join a casino and give an appropriately-themed slot a few spins. Thus, enter the St. Patrick’s Welcome Bonus! Such a bonus can only be redeemed by a first-time player at the casino in question, and this will generally consist of a deposit match bonus and few spins. What’s not to like?

St. Patrick’s Day No Deposit Bonus

An online casino no deposit bonus is simple – it’s a bonus that can be acquired without having to deposit any of your hard-earned cash. Such a bonus will typically consist of free spins, giving you a chance of landing the proverbial pot of gold! 

St Patrick’s Day No/Low Wagering Bonus

It’s always worth reading the terms and conditions of any bonus before committing because, a lot of times, it will involve a wagering requirement. This means you need to bet the bonus cash or any winnings from your spins a certain amount of times before you can actually withdraw it. 

For example, let’s say a St. Patrick’s Day bonus consists of a 100% deposit match of up to £50 with a 40x wagering requirement. In this case, if you want to get the maximum amount from this bonus you need to deposit £50 for the £50 bonus, making a total of £100 in play money. You then need to wager £4,000 (£100 x 40) to meet the wagering requirement. 

Got that all? Because if you did, now you know why you should look for St. Patrick’s Day promotions with a low wagering requirement, if ones without a wagering requirement!

5 Fun Facts about St. Patrick’s Day

  1. Saint Patrick was actually British! — Yes, the lore of St. Patrick is closely connected to the shared histories of Ireland and Britain. In fact, it is believed that he was born in Britain but eventually capture by Irish raiders and sold as a slave. 
  2. Blue was the original colour used for this holiday – it is hard to believe that you could celebrate St. Paddy’s without seeing a sea of emerald green. And yet, the original religious holiday was associated with blue, until shamrocks and green ribbons became fashionable in the 17th century. 
  3. Leprechauns are actually fairies – This one may be strange, but it is indeed true that Leprechauns are based on Celtic fairies, from folklore that says that these small-bodied beings have magical powers that can be used for good or evil. 
  4. Shamrocks are considered to be sacred – the three-leaf clover is the national flower and emblem of Ireland, and has a deep association with the country’s history. It is also revered as being sacred, as St. Patrick’s described it as representing the Holy Trinity. 
  5. St. Patrick’s Day celebrations started in America – The first St. Patrick’s Day celebration in the United States is held in Boston in 1737, which paved the way for this holiday to become the global celebration which we know today.
