By SBK takes its prices from the Smarkets exchange, where punters back and lay against each other, which is why its odds on the big markets often beat the high street. The welcome just asks you to find a 2/1 shot.
The SBK sign-up offer is bet £10, get £40 in free bets: make a £10 first deposit by debit card or bank transfer, place a £10 bet at odds of 3.0 or bigger, and eight £5 tokens are released over 48 hours as football bet builders and multiples that need at least four legs. No SBK promo code is required. SBK has run several versions of this offer in a year, so the figures above are the ones that applied when we checked.
This SBK review covers Smarkets’ own app-first sportsbook: football, UK and Irish racing at exchange-derived prices, tennis, golf, cricket, rugby, basketball, American football and even politics, in-play on the main sports and cash out. We explain how to meet the 3.0 condition without forcing a bad bet and what four-leg tokens are really worth, then the app, the banking and the chat-and-email support.

SBK sign-up offer: what you actually get
Register, make a first deposit of at least £10 by debit card or bank transfer, and place a £10 bet at odds of 3.0 (2/1) or bigger. The £40 then arrives in three instalments: a £5 football bet builder and a £5 horse racing multiple on settlement, three more £5 tokens after 24 hours, and three after 48 hours. Every token is for a bet builder or a multiple with at least four legs, stakes are not returned, and the usual restrictions on markets and expiry apply.
| Term | Detail |
|---|---|
| First deposit | £10 minimum, debit card or bank transfer |
| Qualifying bet | £10 at min odds 3.0 (2/1) |
| Reward | £40 as eight £5 free bets |
| Release | Two tokens on settlement, three after 24 hours, three after 48 hours |
| Token types | Football bet builders and multiples; minimum 4 legs each |
| Stake | Not returned on free bets |
Four-leg tokens change the maths
A £5 free bet on a four-leg multiple is a lottery ticket with good odds attached: four short-priced selections at around 1.5 each make a 5.0 acca, so a winning token returns about £20. Because SBK’s prices come from the exchange, a well-traded football market is often a shade better than the high-street books, which helps every leg. Qualify on a genuine 2/1 shot you would have backed anyway, then build the tokens from favourites rather than long shots.

Pros and cons
What we like
Prices that often beat the high-street books; £40 in free bets for a £10 bet; a fast, plain app; the Smarkets exchange behind it.
What could be better
A 2/1 qualifying bet; tokens restricted to four-leg builders and multiples; released over two days; 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 £40, build the tokens from favourites 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 in a plain sportsbook. On Trustpilot SBK scores 1.9/5 (Poor) from 305 reviews, 31% five-star, 62% one-star; the app is rated 4.6/5 on the App Store from 4.8k ratings and 4.3/5 on Google Play from 2.26k reviews. Praise: reviewers like the clean sports-only layout and odds that beat many UK bookmakers. Complaints: app freezes, crashes and login failures around weekend kick-offs, 6-12 hour withdrawals, denied welcome promotions and slow support. Trustpilot leans towards people with a grievance and store ratings rate the app, so read the newest reviews rather than the headline number.
