The Welcome Pack is the main event of the Slimking promotions page. As its own page stated when it was checked from the UK on 30 October 2026, it spreads up to €10,000 plus 500 free spins over four deposits.
The four rounds
| Deposit | Bonus | Up to | Free spins |
|---|---|---|---|
| 1st deposit | 100% | €2,000 | 150 |
| 2nd deposit | 75% | €2,500 | 50 |
| 3rd deposit | 75% | €2,500 | 100 |
| 4th deposit | 100% | €3,000 | 200 |
| Total | — | €10,000 | 500 |
Every round needs a deposit of at least €20. The percentages differ, so the size of each deposit changes how much bonus it brings: €100 on the first deposit adds €100, while €100 on the second adds €75.
The rules that apply to every round
- Wagering: 30 times the deposit plus the bonus.
- Free spins: their winnings are wagered 30 times.
- Time: 10 days to complete the wagering.
- Maximum bet: €5 per bet while the bonus is active.
- Maximum cashout: not stated on the offer’s page; the general bonus terms may set one.
Two sets of rules
What 30x deposit and bonus means in practice
Wagering is counted on the deposit and the bonus together, which makes it heavier than it first sounds. Three examples:
| Deposit | Bonus | Balance to play | Wagering needed (30x) | At €1 a spin | At the €5 maximum |
|---|---|---|---|---|---|
| €20 on deposit 1 | €20 | €40 | €1,200 | 1,200 spins | 240 spins |
| €100 on deposit 1 | €100 | €200 | €6,000 | 6,000 spins | 1,200 spins |
| €200 on deposit 2 | €150 | €350 | €10,500 | 10,500 spins | 2,100 spins |
Taking the first round in full means a €2,000 deposit and a €2,000 bonus, so €120,000 of wagering in 10 days. For most players a smaller deposit is the better bout: the bonus is smaller, but the wagering is one you can actually finish.
Free spins work separately. If 150 free spins win €20, that €20 needs €600 of wagering before it can be withdrawn.
How to claim it
- Register and pick your account currency. Pound sterling is not offered, so most UK players choose euro.
- Open the cashier and choose a method.
- Deposit at least €20 and make sure the Welcome Pack is selected before you confirm.
- Play eligible games at €5 or less per bet until the wagering is done, inside 10 days.
- Repeat for rounds two to four, if you want them.
Is it worth it?
It depends on how you play. If you play slots most evenings and like a long session, the Welcome Pack stretches your balance a long way. If you play a few times a month, the 10-day clock and 30x on deposit and bonus may be more than you want to take on, and the lighter reloads and cashback could suit you better.
