The welcome package
New players get a 350% match up to €10,000 plus 500 free spins, split across the first four deposits:
| Deposit | Match | Maximum bonus | Free spins |
|---|---|---|---|
| 1st | 150% | €2,500 | 150 |
| 2nd | 75% | €2,500 | 100 |
| 3rd | 75% | €2,500 | 125 |
| 4th | 50% | €2,500 | 125 |
The minimum qualifying deposit is €10 on each tier. Bonuses credit automatically — there is no Spinboss promo code to enter. Free spins release in daily batches of 50 rather than landing all at once, so the value spreads across your first week or so instead of expiring in one session.
How the wagering actually works
This is the number that decides whether a bonus is worth taking, so it is worth being precise. Spinboss applies 35x to the bonus amount only — not to bonus plus deposit, which is the more expensive formulation many operators use.
Worked example. You deposit €100 on the first tier and receive a €150 bonus.
- Wagering requirement: €150 × 35 = €5,250 in total turnover.
- Under the bonus-plus-deposit method used elsewhere, the same offer would demand (€100 + €150) × 35 = €8,750.
That difference — €3,500 of turnover you do not have to place — is the single most important thing to understand about this offer.
Free spin winnings carry the same 35x requirement, calculated on the winnings rather than a notional spin value.
Game weighting
Not every game clears wagering at the same rate:
| Category | Contribution |
|---|---|
| Slots | 100% |
| Crash and instant games | 50% |
| Live casino, blackjack, roulette, video poker | 10% |
| Sports betting | Excluded |
Clearing a bonus on live tables is technically possible but takes ten times the turnover. If you intend to clear the welcome offer, clear it on slots.
The rules that void a bonus
Three restrictions account for almost every voided bonus. None of them are unusual, but all of them are easy to trip over:
- Maximum bet €5 per spin or hand while any bonus is active. Exceeding it — including through a bonus-buy feature priced above €5 — can void the bonus and the winnings from it. Check your stake before you spin, particularly after switching games.
- 30-day expiry. Unwagered bonus funds are removed 30 days after credit. Free spins expire 7 days after release.
- One bonus at a time. A new bonus cannot be claimed while another is still in wagering, and one welcome package is permitted per person, household, IP address and payment method.
Bonus funds are always played after cash funds are exhausted, and withdrawing while a bonus is still in wagering forfeits the remaining bonus balance.
Ongoing offers
- 10% weekly cashback on net losses, credited every Monday with no wagering requirement and no opt-in. This is the most valuable recurring offer on the platform precisely because it is real cash rather than another bonus to clear.
- Reload bonuses on scheduled deposit days, typically 50% up to €500 at 35x.
- Free spin drops tied to new releases and featured titles.
- Daily Slots Rush tournament — leaderboard points on every qualifying spin, scored on win-to-bet ratio rather than stake size, reset every 24 hours, no entry fee.
- VIP programme — tiered, with faster withdrawals, higher limits, personalised reloads and a dedicated account manager at the upper levels.
Is the welcome offer worth taking?
If you are depositing near the tier minimums and playing slots, yes — 35x on the bonus alone is a genuinely competitive requirement, and the staged release keeps the headline figure within reach of ordinary bankrolls. If you play mainly live dealer games, the 10% weighting makes the welcome package poor value; take the weekly cashback instead and skip the bonus entirely. Declining a bonus is always an option, and on a live-casino-heavy account it is usually the better one.
