OneCasino Bonuses and Promotions

At OneCasino Ireland, your experience starts with a bonus. Enjoy a range of online casino bonuses, including a welcome casino bonus, weekly casino promotions, no deposit casino bonus, and exclusive rewards tailored to our Irish players.

Welcome Bonus at OneCasino Get ready for a warm welcome at OneCasino with a no deposit casino bonus in the form of a cash reward upon registration, just sign up and start playing instantly. First impressions matter, and at OneCasino, we believe your first should be exciting and rewarding. As a new member, you'll receive a € 10 bonus to kickstart your journey. But that’s just the beginning! On top of that, new members get an extra 100% on their first deposit, up to € 100. This means you have the opportunity to decide how much your bonus will be.

How to Claim Your Welcome Bonuses:
The first €10 bonus is credited to your account as soon as it’s active, following the confirmation of your identity and age. You’ll find the € 10 in the "Bonus" section of your new account. Please note, you can claim your casino welcome bonus once you've verified your bank account by authorizing a € 0,01 transaction, which is refunded once we confirm your account.

Different conditions may apply to special or temporary (welcome) bonuses. These are indicated on the specific page for that bonus.
100% Bonus on your first Deposit As a new OneCasino member, you are instantly in first place! You will receive 100% extra on your first deposit (up to € 100). Discover our offer with a little extra! We add your bonus as soon as you make your first deposit. The 100% extra on your deposit is added to your bonus money and can be used immediately on your favourite slots, golden oldies, exclusive games or in our live casino.

How to receive the 100% deposit bonus:
After you've opened your OneCasino account, you'll immediately receive your welcome bonus of € 10. This is separate from your deposit bonus and is a free bonus. On the first deposit to your casino account, you'll receive the 100% deposit bonus. It will be added to your account together with your deposit amount.
Tuesday and Friday Bonuses If you aren't new to OneCasino, you are still number one. All our players receive a bonus every Tuesday and Friday. The Terrific Tuesday bonus is a deposit bonus you can claim every week. On Fridays, our players receive the Fantastic Friday Bonus to get your weekend off to a banging start. The Friday Bonus includes a deposit bonus and, depending on your Club One level, free spins or a money bonus. Once a month, this bonus gets an upgrade and will be even higher!

This is how you receive the weekly bonuses:
We'll send you a message through an email, pop-up, text message or push notification to let you know your bonus is ready. In your OneCasino account, you can specify the way(s) you prefer to be notified. Easy-peasy!
Spin to Win Spin the wheel and be surprised by a prize! The wheel can appear at any moment, and the prizes include free spins, money bonuses, and deposit bonuses. Spin to Win is our surprise game that randomly appears. It doesn’t matter how often you play with us or how long you’ve been a member: all players who have ever made a deposit can participate. The prizes on the wheel consist of free spins and deposit bonuses.

After the first round, you could be lucky enough to enter the jackpot round. Only players with Club One level Special or higher, or those with a lower level who deposited the last week, qualify for this round if it pops up. In this extra round, it’s all about cash bonuses. You could win a range of cash rewards to enjoy at our casino. Will you spin when the wheel appears?

The Fine Print of Our Casino Bonuses

At OneCasino, we keep things simple. Our online casino bonuses come with clear, fair terms, there will be no hidden catches.

Deposit bonuses are for use on our casino games, and if a specific bonus (like a casino welcome bonus) has unique conditions, you’ll find all the details right on its promo page or in the disclaimer. We make sure you always know exactly what to expect so you can focus on enjoying OneCasino.

What is a Casino Bonus?

An casino bonus is often in the form of extra play money or a deposit bonus that is added to your casino account. Sometimes free spins are included in a casino bonus.

Bonuses at OneCasino

At OneCasino, we aim to offer you some of the best casino bonuses like money bonuses, deposit bonuses, and free spins. New players receive a free bonus without making a deposit, as well as a deposit bonus on their first deposit. Existing players receive the Terrific Tuesday Bonus (deposit bonus), the Fantastic Friday Bonus (variable), and the Mega One Bonus.

  • Money Bonus: A bonus without any strings attached. This money is deposited into your casino account to use in our casino.
  • Deposit Bonus: A deposit bonus is extra credit you receive based on the amount you deposit. For your first deposit, you’ll receive a 100% bonus up to a maximum of € 100. This bonus has a 35x wagering requirement and is classified as a first deposit bonus.
  • Free Spins: You receive free spins for selected slots. The moment you open one of the slots, you can spin for free.

What is the Best Casino Bonus?

The best casino bonuses depend on your personal preferences. A deposit bonus is ideal if you intend to deposit money, however free spins on your favorite game may be more exciting for you. A no-deposit bonus is enjoyable since you have complete control over how you spend it. The key to a great bonus is fair value paired with reasonable terms.

The Difference Between Bonus- and Saldo money

The money in your casino account is found under 'Balance' and is divided into Saldo and Bonus. Your Saldo, also called real money, is the money you can withdraw and does not depend on wagering requirements. Bonus money is received through a bonus and must be wagered before you can withdraw it. If you have both forms of money in your account, your Saldo money will be used first when you play.

Wager and Withdraw Your Online Casino Bonus

After you fulfill the wagering requirements, you can withdraw your online casino bonus. The money is then changed from Bonus to Saldo and is available for withdrawal.

What are Wagering Requirements of Bonuses?

The wagering requirements specify how often the bonus amount must be wagered before it can be withdrawn. For example, a bonus might have a wagering requirement of 35 times. This means you must wager the amount 35 times on casino games before it can be withdrawn.

Types of bonuses and wagering

We offer three types of bonuses: regular bonuses, no-wager bonuses, and balance-wagered bonuses. Each has its special advantages and its own wagering requirements. The maximum bet for our bonuses is € 5 for all our bonuses. This rule does not apply to bonuses above € 1 000.

Regular casino bonus

Regular bonuses such as our weekly no-deposit bonus can only be wagered using the bonus funds themselves. Each regular bonus comes with a specific wagering requirement.

For example, a 25x wagering requirement means you must wager the bonus amount 25 times before you can withdraw. So, if you receive a € 1 bonus, you’ll need to wager € 250 to meet the requirement.

Once the requirement is met, the bonus amount is transferred to your balance and becomes eligible for withdrawal.

No-wager bonuses

We also offer no-wager bonuses, like One Casino’s Cash Back. With these, any winnings from your Cash Back are added directly to your balance as real money and no additional requirements apply.

Please note: if you request a withdrawal, your no-wager bonus will be removed and cannot be reinstated, even if the withdrawal is later cancelled.

Balance-wagered bonuses

These bonuses are wagered using funds from your balance meter. Once your cash balance is depleted, you will automatically begin playing with your bonus balance. All winnings from a balance-wagered bonus are added to your balance.

Important: if you request a withdrawal, your balance-wagered bonuses will be removed and cannot be recovered, even if the withdrawal is cancelled.

Do OneCasino Bonuses Have an Expiry Date?

Yes, most casino bonuses including our weekly casino bonus have an expiry date. If the bonus has not been used or met the wagering requirement by the expiry date, the initial value of the bonus is deducted from the bonus value.

If you played with the bonus and won money, making the bonus value higher than the initial value, your bonus remains valid, and you have extra time to wager it.

The initial deposit bonus is lost if you make a withdrawal request while your bonus is still active.
