Before you start: three things to check
Claiming a welcome bonus should be simple. And it usually is — provided you do three things before you deposit a single cent.
First, confirm the offer is available in your country. Many bonuses are geographically restricted. This information is almost always buried at the bottom of the terms page rather than displayed prominently next to the big headline number. Check it before you go through the whole signup process.
Second, read the wagering requirement. Not the headline amount — the rollover. A €500 bonus with a 40x wagering requirement means you need to bet €20,000 before you can withdraw. That's not a gift; that's a challenge. Make sure you understand what you're committing to. If you want a deeper breakdown of how these work, read our wagering requirements guide.
Third, check the time limit. Missing a deadline means the bonus is forfeited — sometimes along with any winnings made from it. Know how long you have before you start.
The rule of thumb: if the T&Cs are longer than this article, something in there probably isn't in your favour. Sites with genuinely fair terms tend not to hide them.
Step-by-step: from signup to bonus
Here's the exact process for claiming a welcome bonus, using Thunderpick as a working example — since it's the offer we currently recommend most highly.
Common mistakes that void bonuses
These are the errors we see come up again and again in user complaints. All of them are avoidable:
- Depositing via an excluded payment method. Many operators exclude PayPal, Skrill, Neteller and some crypto wallets from bonus eligibility. Check the payment method terms before you deposit.
- Placing bets below the minimum odds. If the rollover requires bets at 1.5 or higher, a bet at 1.3 contributes nothing. You can still place low-odds bets — they just won't count toward your clearance.
- Exceeding the maximum stake per bet. Some bonuses cap individual bet sizes (e.g. no single bet over €50 while on bonus funds). Exceeding this can void the entire bonus, not just that bet. This is one of the most common and most unfair gotchas in bonus terms.
- Withdrawing before clearing the rollover. Withdrawing real-money funds before your wagering requirement is complete often voids the remaining bonus. If you want to withdraw early, check whether this is permitted and what happens to the bonus balance.
- Using a VPN. Operators flag accounts that appear to access from a different country than registered. VPN use during bonus claiming or wagering is grounds for account suspension at most major operators.
If something feels wrong — the bonus hasn't appeared, a bet didn't count, your account is showing odd restrictions — contact support in writing (live chat with a transcript, or email) and keep a record. Documentation matters if you ever need to escalate a dispute.
Your pre-claim checklist
Run through this before you deposit on any new platform:

The process takes less than five minutes when you know what you're doing. The operators who make it harder than this are usually compensating for terms that wouldn't withstand scrutiny if they were simple and upfront.
Our current top pick — Thunderpick — passes every item on this checklist with room to spare. Low rollover, clear terms, a 30-day window, and a bonus that works across sports, esports and casino. It's the first offer we'd point any new bettor toward.
