Smooth Spins Bonus Codes (2025)

What the Smooth Spins Free Spins Offer Actually Delivers

Smooth Spins keeps it simple: deposit £10, play it on any Big Bass slot within 7 days, and you’ll receive 100 free spins on selected Big Bass titles. The spins are credited automatically once you’ve wagered the £10, and they’re valid for 7 days from the moment they hit your account. We tested this during our review session—deposited £10 via Visa, played Big Bass Bonanza, and the spins appeared within seconds of completing the £10 playthrough.

The catch? You must opt in before depositing, and the £10 must be played specifically on Big Bass slots. Blackjack and roulette don’t count, which is standard but worth noting if you planned to spread your deposit across table games. The free spins themselves come with wagering requirements—typically 35x on winnings—and there’s usually a maximum cashout cap, though Smooth Spins doesn’t advertise this upfront. From what we’ve seen on similar offers, expect a cap somewhere between £20 and £400.

The offer is straightforward, but it’s built for slot players who already enjoy the Big Bass series. If you’re not into that style of game, this bonus won’t add much value.

Payment Methods Available for Smooth Spins

Key Terms That Shape This Bonus

Opt-In Required: You can’t just deposit and expect the spins. You need to opt in through the promotions page before making your £10 deposit. Miss this step, and you won’t qualify.

7-Day Activation Window: Our experts saw that you have 7 days from registration to deposit and play the £10. If you don’t complete this within the timeframe, the offer expires. Once you receive the spins, you have another 7 days to use them before they vanish.

Big Bass Slots Only: The £10 playthrough must happen on Big Bass titles. The free spins are also locked to selected Big Bass games. If you prefer other slots, you’ll need to adjust your usual play style to claim this.

Wagering on Winnings: Winnings from the 100 free spins come with a 35x wagering requirement. Win £10 from the spins? You’ll need to wager £350 before you can cash out. It’s standard practice, but worth doing the maths before you commit, especially if you’re not planning a longer session.

Maximum Cashout: Smooth Spins doesn’t spell out a cashout cap in the main terms, which is frustrating. Most free spin offers like this cap withdrawals somewhere between £20 and £400. We’d assume a cap exists until proven otherwise. Treat anything above that as a nice surprise, not a given.

Excluded Payment Methods: All payment methods work for this offer such as Visa, Mastercard, Apple Pay, Google Pay. No e-wallet exclusions here, which is refreshing. Some UK casinos still block Skrill or Neteller from bonuses, but Smooth Spins doesn’t play that game.
