What is a welcome bonus?
A welcome bonus is the introductory offer a bookmaker or casino gives to newly registered players. Most often it takes the form of a first-deposit bonus: you fund your account, and the operator adds a percentage of your deposit on top. For example, with a 100% bonus, if you deposit $200, another $200 lands in your bonus balance.
But that extra amount doesn't turn into cash straight away. It sits in a separate bonus balance and only moves to your real balance once the wagering requirements have been met. So understanding a welcome bonus means, first and foremost, understanding its terms.
Some operators don't limit the welcome offer to a single deposit and instead split it into a package across several deposits: a separate percentage and free spins for the first, second and third deposits. With packages like these, the advertised headline amount is only received in full if you complete every stage, and each stage has its own wagering and deadline.
How a first-deposit bonus works
- You register on the operator's website and fill in your profile details.
- On the registration form you choose the bonus type (sports or casino) and, if needed, enter a promo code, for example
XBUNKER. - You make a first deposit of at least the minimum amount (card, e-wallet, local payment method or crypto).
- The bonus is credited automatically to your bonus balance.
- You bet the bonus with the required turnover within the set deadline.
- Once the conditions are met, the bonus funds move to your real balance and can be withdrawn.
Sports bonus or casino bonus: which should you choose?
Many operators ask you to pick one of two directions when you register. They differ significantly:
| Criterion | Sports bonus | Casino bonus |
|---|---|---|
| What you get | A percentage on your deposit, sometimes a free bet | A percentage on your deposit + free spins, often split across several deposits |
| How it's wagered | Accumulator bets with minimum odds | Bets on slots, with each game contributing differently |
| Typical wagering | Lower | Higher |
| Who it suits | Regular football and sports bettors | Fans of slots and casino games |
A simple rule: take the bonus for the games you usually play. Choosing the casino package just because the percentage is bigger, and then trying to wager it on sports bets, won't work — a bonus can only be wagered in its own section.
A worked example
Let's calculate a simple sports bonus. Suppose the deposit is $200, the bonus is 100%, wagering is x5, and each accumulator needs at least 3 selections, each priced at no less than 1.40.
| Item | Value |
|---|---|
| Deposit | $200 |
| Bonus (100%) | $200 |
| Required turnover ($200 × 5) | $1,000 |
| Number of $20 accumulators | at least 50 |
These figures are only an example — the real percentage, wagering and odds requirements are set out in the operator's current terms. But the logic of the calculation is always the same: bonus × wagering = turnover. The same maths works in any currency, whether you play in rupees, naira, shillings or dollars.
Checklist before claiming a welcome bonus
Before activating a bonus, spend a few minutes finding the answers to these questions. It will save you a lot of frustration and lost bonuses later:
- What is the minimum deposit? If you deposit less, the bonus may not be credited at all.
- Does the wagering apply to the bonus only, or to bonus + deposit? In the second case, the turnover doubles.
- How many days do you have to wager it? Work out in advance how much you need to bet per day.
- Which bets count? For sports — the minimum odds and number of selections per accumulator; for casino — the game contribution rates.
- Is there a maximum bet and a maximum win? These two rules are often in the small print.
- Does the deposit method affect the bonus? Some promotions don't work with certain payment systems.
If you can't find the answer to any of these, write to support before activating the bonus and save a screenshot of their reply. It will help you if a dispute arises later. Also fill in your profile with your real details — at the verification stage before withdrawal, they must match your documents.
