Today's races are done.
The board will reset with tomorrow morning’s cards. Check back later.
Look for conversion 95%+. These have the closest back/lay prices, meaning the smallest qualifying loss or the highest free-bet retention. Lower-conversion matches still work - they just cost more on the qualifying side.
Click "Open in calculator" on any card. The bookmaker odds, Smarkets lay price, and exchange are pre-filled. Enter your stake and the lay stake calculates automatically.
Verify the odds are still live (markets move), place the back bet at the bookmaker, then the lay bet on the exchange. Same outcome, same selection on both. That's it.
The board is built around Smarkets for the lay side. We keep the workflow on one exchange because its standard commission is lower and the execution is simpler for most users.
The bookmaker and the exchange do. BeatTheBookies is independent and does not control their prices, markets, promotion rules, identity checks, or settlement decisions. Treat the board as a live shortlist, then confirm everything on the operator pages before placing.
Exchange liquidity builds as an event approaches - back/lay spreads tend to tighten in the 1–24 hours before kick-off as more traders enter the market. For most qualifying bets, checking the board the morning of the event or a few hours before start gives the best combination of choice and tight spreads. That said, always verify both prices are still live at your bookmaker and exchange immediately before placing - odds can shift in seconds.
The board rescans every 3 minutes. Markets move fast in the hour before an event starts - always verify bookmaker odds and the Smarkets lay price are still live in your bookmaker and exchange before placing. Calculator output is only as accurate as the odds you enter.
Football, tennis, cricket, basketball, NFL, ice hockey and other two-way markets are scanned when fixtures are available. Exchange lay odds for horse racing aren't available from the live odds feed, so there are no back/lay rows for racing. Instead the Today's Racing section above shows today's UK & Irish racecards with best available bookmaker prices - find the lay on Smarkets yourself to complete the match.
