Refer a Friend at Slamz

By Elin Norrgård, casino analyst — updated August 2026

The refer a friend scheme pays both sides when someone you invite becomes an active player: typically €25 each once the new account has deposited €20 and staked €100, with 25x wagering on the reward. It is the only offer here where the money comes from your address book rather than your wallet, and the only one with an obvious social cost attached.

How the invite works

1. Open the referral section of your account and copy your personal invite link or code.
2. Send it to someone who already plays or has genuinely decided to. This matters more than the mechanics.
3. They register through that link — the connection is made at sign-up and cannot be added later.
4. They deposit at least €20 and stake €100 of real money.
5. The referral bonus is credited to both accounts, usually within 48 hours of the threshold being met.

Conditions that decide whether it pays

• New accounts only. An invite friend bonus does not apply to anyone who has held a Slamz account before, on any email address.
• One household, one account. Shared devices, shared IP addresses and matching payment details all trigger a review, and the reward is withheld.
• Wagering. The €25 arrives as bonus balance at 25x, so €625 of turnover stands between it and a withdrawal.
• Verification. Both accounts must be verified before either reward is released.
• Cap. Most versions limit you to a handful of paid referrals per month.

Why most referrals never pay out

The €100 turnover requirement is where the majority die. Someone who signs up out of curiosity, deposits the minimum and plays for twenty minutes will not reach it, and the invite simply lapses. That is by design: the operator is paying for players, not for registrations. Before you send a link, ask yourself honestly whether the person on the other end was going to play anyway — if the answer is no, you are not earning €25, you are recruiting someone into gambling for a commission that will probably never arrive.

Where it fits against the other offers

As a source of value the invite friend route is unreliable and slow compared with the weekly cashback, which needs nothing from anyone else, or the reload bonus, which is available every week. It is worth using when a friend has already asked you which casino you play at, and worth ignoring otherwise. The reward is also separate from the affiliate arrangement that funds this site — see our affiliate disclosure for how that works.

If the reward does not appear

Check three things before contacting anyone: that the friend registered through your link rather than typing the address directly, that their deposit cleared rather than failing at the bank, and that the €100 of turnover was placed on eligible games. If all three hold and 48 hours have passed, live chat can see both accounts and resolve it — have the friend's username ready, since without it the request cannot be traced.
