Do You Need an OnlySpins Bonus Code?
No. This trips up a lot of players arriving from Google, because most traditional UK casinos still use code fields. OnlySpins does not — the welcome offer attaches to your account automatically when you register and make a qualifying deposit.
If a site is selling you an "exclusive OnlySpins code", treat it with suspicion. There is no code to sell.
How to Claim — Step by Step
| Step | Action |
|---|---|
| 1 | Register an OnlySpins account (email only, no ID) |
| 2 | Go to the cashier and select Bitcoin or USDT |
| 3 | Send at least ~£15 equivalent from your wallet |
| 4 | Match credits automatically once the deposit confirms |
| 5 | Free spins release on the current featured slot |
Wagering Requirements — Read This Before Depositing
The deposit match and the free spins carry separate wagering terms. This matters more than the headline number: a 100% match is easy to clear at 25x and painful at 45x, and the difference is not visible from the promotional banner.
Check the current figure in the cashier before you deposit — crypto casinos revise these more often than licensed UK operators, and any number published on an affiliate site can be out of date within weeks.
Is the OnlySpins Bonus Worth It?
Against the rest of our rankings, this is a mid-sized offer with an unusually clean structure. BC.Game's 300% up to £15,000 is far larger in headline terms, but the playthrough scales with it.
| Casino | Welcome Offer | Free Spins |
|---|---|---|
| OnlySpins | 100% match | 200 |
| BC.Game | 300% to £15,000 | — |
| BitStarz | 5 BTC package | 180 |
| SpinEmpire | 200% to £2,500 | — |
| GambleZen | 150% to £1,500 | — |
OnlySpins offers the most free spins of any casino in our rankings. If you primarily play slots, that tilts the comparison in its favour despite the smaller deposit match.
