How do I add a runner to my betslip?
On any runner on today’s racecards, tap “Add to betslip”. Your selections collect in a betslip you can open at any time from the floating betslip button — pick from as many races as you like.
Does it cost anything, or do I need an account?
No. The betslip and calculator are free, with no sign-up. We earn a commission only if you later choose to open a bookmaker account through one of our links, and that never changes the figures you see — it is what keeps the tool free.
Is this a tip?
No. The betslip prices the bet you choose; it does not tell you what to back. For our read on each race, every racecard carries the KTB analysis — but the decision stays with you.
How are the combined odds worked out?
We convert each selection’s price to decimal, combine the legs according to your chosen bet type (including every separate line in a full-cover bet such as a Lucky 15), and convert back to the total return for the stake you enter.
Can I see which bookmaker pays the most?
Yes. Once your slip is built, Find your best payout compares the bookmakers and shows which one returns the most on your exact bet.
Where can I get help staying in control?
Set a budget before you bet and treat it as entertainment, never income. Our responsible gambling support page has practical tools, and free, confidential help is available through GambleAware.
