- Welcome Pack – four-stage match bonus with free spins on every deposit
- Alternative Welcome – single 150% package for players who deposit once
- Sport Welcome – sportsbook-only match bonus, separate from the casino offers
Spinfin operates on a Curaçao licence outside GamStop, a detail that matters for players in the United Kingdom who want an alternative to UKGC-licensed sites. British customers still get standard 18+ checks and the same deposit limits as everyone else.
The Spinfin welcome bonus & sign-up package
The Spinfin welcome bonus runs across the first four deposits rather than a single top-up. Match rates rise and fall by stage, and free spins are attached to every one of them.
| Stage | Match & spins |
| 🎁 First deposit | 100% up to £2,000 + 150 FS |
| 💰 Second deposit | 75% up to £2,500 + 50 FS |
| 🚀 Third deposit | 75% up to £2,500 + 100 FS |
| ⭐ Fourth deposit | 100% up to £3,000 + 200 FS |
Combined, the four stages add up to the headline Spinfin promo code offer – up to 350% plus 500 free spins, capped at £10,000. Players who only make one deposit collect just the first-stage match; the remaining three stay unclaimed until later top-ups land. That structure keeps the offer relevant for return visits from the United Kingdom throughout the first month.
Spinfin free spins: how to claim your extra rounds
Spinfin free spins arrive in batches tied to each Welcome Pack deposit rather than one lump sum. The first deposit unlocks 150, the second and third add 50 and 100, and the fourth closes the set with 200 more.
Winnings from free spins land as bonus funds, not cash, so they carry the same wagering requirement as the matched deposit before a withdrawal request goes through. Players who pick the Alternative Welcome instead get 200 spins in one block alongside the 150% match, with no staged rollout.
