How to select a St. Patrick’s Day casino bonus

There are plenty of casino promotions, each with their underlying T&Cs, so picking the best St Patrick casino bonus can be tricky. We understand your situation, so we’re here to help. Here are a few crucial terms and rules to check when comparing these bonuses and promotions.

• Fair wagering requirements: The wagering or playthrough requirement is a standard condition for most bonuses. It explains the number of times players need to wager the bonus (or including the deposit) before making a withdrawal. A wagering requirement between 10x to 40x is most common.

• Bonus expiry: Watch out for the bonus offer expiration when comparing offers. The longer the expiry length, the better it is for players. Most sign-up bonuses and free spins are valid for 30 days, but St. Patrick’s Day offers may be limited to around the festive period.

• Game eligibility: You may only be able to play certain bonuses on specific games. These festive bonuses may be limited to St. Patrick’s Day-themed slots, for example.

• Bonus codes: Bonus or promo codes are a string of numbers, characters, or letters players can use to claim a specific bonus.

• Value of free spins: Aside from the minimum deposit and qualifying games, free spins bonuses also have a minimum spin value. Often, spins are valued at €0.10, with a max bet and a cap on winnings.

Here’s a quick look at the top St Patrick’s Day casino promotions you can find right now:

• Welcome bonuses

Welcome bonuses

Welcome or sign-up bonuses are a casino’s biggest draw to new customers. You can claim the bonus after completing and verifying your account and making your first deposit. Most casinos feature a welcome deposit bonus bundled with free spins. For example, Oshi Casino’s welcome promotion offers up to €300 plus 250 free spins. Other casinos may double your initial deposit, or even reward you with a lucrative 200% deposit match bonus.

Deposit match bonuses

Deposit match bonuses reward new and existing players for deposits on the platform. Often, the bonus is a percentage of the total amount deposited to the player’s real money accounts. For example, casinos may feature a 30% deposit match bonus up to €100.

No deposit bonuses

A no deposit casino bonus is credited to your account without a deposit requirement. Upon registering or verifying your account, new players often receive these bonuses. No deposit bonuses come as bonus cash or free spins, usually smaller than the usual welcome offers or deposit bonuses.

Free spins

Free spins are popular bonuses during St. Patrick's Day period, offering players the chance to try out qualifying slot machines risk-free. You can claim these bonuses at any point during your site membership — as part of the sign-up offer, a no deposit bonus, or a weekly stand-alone promotion. Like most bonuses, free spins offers are subject to T&Cs, including minimum deposit, qualifying games, playthrough restrictions and validity period.

Casino cashback offers

If you’re a regular player, you can’t go wrong with the cashback bonus. Also called rebate, a cashback casino promotion gives back a portion of your total wager or net losses on a given week. For example, a casino may award you a 20% cashback for your net losses, with just 1x wagering requirement. If you opt-in, look for a higher reward percentage with the lowest or no wagering requirement.

Slot tournaments

Looking for some challenges while celebrating St. Patrick’s Day? If so, you may want to join one of the thrilling slots tournaments hosted by casino sites. In order to take part, players must opt in and then play the qualifying online slots using the minimum bet, and collect points. Your aim in slots tournaments is to collect points on your wager, and dominate the leaderboard for a share of the prize pool.

St Patrick’s Day casino bonus terms and conditions to watch out for

Whether you’re a fan of welcome bonuses with free spins, cashback or slots contests, you’ll find the best promotions to keep you company this month. But before you dig in, don’t forget to assess and compare these bonuses by looking at their specific T&Cs.

Wagering requirements 

Don’t skip the wagering requirements when comparing and shopping for bonuses. As a rule, consider a lower wagering casino bonus to have restrictions from 10x to 40x. Lady Luck smiles on you if you can find a bonus with a 1x wagering or no requirement!  

Bonus expiry

Bonuses expire, and it’s frustrating if you can’t use these because of their short validity period. Traditional bonuses come with a 3-day or even 24-hour validity. But if you compare your options and check what we have included in our guide, you’ll find bonuses with a 30-day validity. St. Patrick’s Day bonuses may be limited to a few days around the day itself. 

Eligible games 

Some casino bonuses, particularly welcome bonuses and free spins, specify the applicable games. Keep an eye on the qualifying games and minimum bets to play on these titles. Using your bonus on other games may forfeit the bonus or even any winnings accumulated. For example, you may have to use your bonus on St Patrick’s Day slots, like Irish Crown. 

Winnings caps 

Aside from the betting limits, many casinos also impose caps on winnings when using the bonus. For example, the casino may cap your winnings at 50x the bet, meaning you cannot withdraw more than that amount.

Minimum deposit 

Casinos require their players to make a minimum deposit, often €20, to qualify for and activate the bonus.  Speaking of bonuses, keep an eye on the operator’s restrictions on deposit options — some of the operators on our list exclude specific banking options. For example, Slotbox Casino excludes Skrill and Neteller deposits from its welcome bonus promotion.

Withdrawal restrictions

Before claiming a bonus, don’t forget to check its payout rules. In addition to the standard withdrawal limit, casinos impose specific withdrawal restrictions. For example, players must first satisfy the wagering requirements or follow the cap on winnings. Other casinos boast a highly specific condition, like putting a cap of €50 on winnings from a no deposit bonus. Often, these conditions are buried deep down in the T&Cs.

Player restrictions 

Casinos restrict players’ access to bonuses in compliance with their licensing requirements and commitment to fair play. For a start, most casinos require players to be at least 18 years old from one of its approved jurisdictions to sign up and claim a bonus. As part of the KYC process, each bonus is limited to just one per person, including email address, phone number, and IP address.

Bonus abuse

Operators also strive to promote a fair and transparent gambling environment for all. As such, most operators highlight their policies on bonus abuse. Different casinos will have varying definitions of bonus abuse. Generally, it refers to a player trying to find a way around the T&Cs to claim and use bonuses, such as using VPNs, multiple accounts, bonuses, and exploiting loopholes.
