By SBK takes its prices from the Smarkets exchange, which is why the odds often beat the high street; the £60 welcome needs a bet at 2/1 or bigger. This SBK review covers Smarkets’ app-first sportsbook, its exchange-derived prices, cash out and an SBK welcome offer of bet £20, get £60 in free bets for a £20 bet at 3.0 after a £10 first deposit, credited within 48 hours, no promo code. We qualified at 2/1, used the free bets and withdrew; the markets, the app and the payouts are below.
SBK is Smarkets’ own sportsbook: instead of a trading desk setting prices, it takes them from the Smarkets exchange, where punters back and lay against each other, and applies a margin. In practice that means prices that often beat the high-street books on the big markets, in a plain app built around football and racing.
The sign-up offer is bet £20, get £60 in free bets. We opened the account, placed the qualifying bet, used the free bets and withdrew, and this is how it went.

Exchange prices and free bets

Pros and cons
What we like
Prices that often beat the high-street books; £60 in free bets; a fast, plain app; the Smarkets exchange behind it.
What could be better
A £20 qualifying bet; fewer promotions and markets than the biggest books; no phone line.
Our verdict
SBK is the sportsbook for value hunters who do not want an exchange’s complexity. Take the £60, use it at bigger odds and let the exchange pricing do the rest.

What do reviews say about SBK?
In our own review SBK scores 72/100, and we rate it best for exchange-derived prices. Player reviews on the App Store, Google Play and Trustpilot tend to split on the same lines as ours: praise for prices and free bets, complaints about verification delays on first withdrawals. Read the most recent ones, as operators change platforms and terms, and treat any review that promises guaranteed wins as spam.
