Unibet Casino Bonus Code: Get 300 Free Spins When You Stake £30
Unibet Casino has refreshed its new-player welcome offer for the new season, and it is a big one for slots fans: stake £30 on slots and you will bag 300 free spins on Big Bass Splash.
It is a no-code, opt-in deal that lands just as the Premier League and NFL seasons kick off - ideal if you fancy a spin between matches.
Here is exactly how the Unibet Casino welcome bonus works, who qualifies and how to get the most from your 300 spins.
How The Unibet 300 Free Spins Offer Works
This is a straightforward, new-customer promotion for players in Great Britain. There are no tiers to worry about — opt in, deposit and stake £30 on slots, and Unibet credits you with 300 free spins to use on Big Bass Splash. At a glance:
| Offer detail | What you get |
|---|---|
| Welcome offer | 300 free spins |
| Qualifying stake | £30 on slots |
| Spin value | £0.10 per spin (300 × £0.10) |
| Featured game | Big Bass Splash |
| Wagering on winnings | 10× |
| Payment methods | Debit card or instant bank transfer only |
| Claim window | Within 7 days of registering |
| Spins expiry | 48 hours after being credited |
Any winnings from your free spins carry a 10× wagering requirement before they can be withdrawn as cash. You must be 18 or over, a new Unibet customer and located in Great Britain to take part.
How To Register And Claim Your Spins
Getting set up takes only a few minutes:
- Open a new Unibet account and verify your details.
- Opt in to the 300 free spins promotion.
- Deposit and stake £30 on slots using a debit card or instant bank transfer - these are the only qualifying payment methods.
- Claim within 7 days of registering, then use your spins on Big Bass Splash within 48 hours of them landing.
Keep an eye on the clock: because the spins expire 48 hours after they are credited, it is worth setting aside a session to use them rather than letting them lapse.
Playing Your Spins On Big Bass Splash
All 300 spins are set for Big Bass Splash, Reel Kingdom's high-energy fishing slot with a free spins round in which caught fish carry cash values and multipliers.

Make Your Spins Go Further
Free spins are most rewarding when you understand what you are playing. Every slot has a published return to player (RTP) percentage - the theoretical share of stakes it pays back over the long run - and knowing it helps you judge value.
Our explainer on how return to player works breaks down what those numbers really mean.
It also helps to know the basics of volatility, paylines and bonus features before you spin.
If you are newer to the format, our guide to how slots work covers everything from reels to random number generators.
