Welcome To OnTheBallBets

OnTheBallBets provides a comprehensive set of guides to a selection of online bookmakers, details of their free bets, and helpful resources for betting sports.

Our Main Areas Of The Site

With such a wide range of sports betting sign-up offers available, it’s normal for punters to be a little overwhelmed. Many of the best free bet offers seem too good to be true – and that can often be revealed once the terms and conditions have been thoroughly checked.

This is where a site like OnTheBallBets comes in handy – as we’ve rated and categorised the best online betting sites allowing players to quickly claim and withdraw the best deal possible.

  • OnTheBallBets allows you to get the best signup deal from the top betting sites in the UK. We provide instructions and screenshots on how exactly you claim your bonus, along with simplified terms and conditions to ensure you don’t get caught out.
  • We’ve done all the hard work for you – we’ve listed what we consider to be the best bookmakers on the web. We show you where you can quickly and easily grab a free bet or big bonus that doesn’t require any hard work to withdraw it.
  • They’re each been given a rating – so you know where to start. We’ve written detailed guides on exactly how to register, how to deposit, how to obtain the free bet or bonus and then how to withdraw it.
  • Where to start? We reckon the ‘Top Bookies’ we’ve listed above are seriously worth checking out. If you don’t have an account with any of them then get signed up. These bonus offers aren’t gonna be around forever – so you better claim them whilst you can!

Why We Created The Site

Joining a betting site is quite simple, but navigating your way through the bookie terms and conditions to actually claim the bonus/free bet and be able to withdraw it can be a complex process. In 2013 we noticed a real lack of betting sites that properly explained the sign-up process and how to withdraw bonus funds.

So, as we’re online betting experts, we took it upon ourselves to create OTBB – a simple website that gives punters exactly what they want.

Get started with our complete list of bookmakers and their new customer offers. Use the links below to get in touch with us or to read more about our history and the OTBB.

Sports We Cover

At OnTheBallBets we cover a number of sports, with both betting site recommendations, betting offer recommendations, and betting guides for each sport.

Sports we cover:

Football

Football is currently the biggest sport we have on the site. You can find the recommended football betting offers for new and existing customers here.

We also extensively cover major sporting leagues and tournaments, including the 2022 Fifa World Cup, The Premier League, The EFL Championship, and The Champions League.

You’ll also find our preferred football betting websites here and top football betting apps on this page.

Our betting guides cover football extensively. View our football betting guides hub, which includes our mega guide to football betting markets. We dive into each one and explain exactly how they work – with details on over 2.5 goals, Asian Handicaps, Under 2.5 goals, both teams to score, corners betting and cards betting.

Horse Racing

Horse racing is massive in the UK, so we’ve covered the best horse racing betting websites, along with the best horse racing betting apps. In terms of offers, we list introductory and ongoing horse racing promotions on this page.

We then drill down and provide you the best deals and advised bets for each of the festivals and big meets, including Cheltenham, The Grand National, Royal Ascot, Glorious Goodwood, Arc de Triomph, The Breeder’s Cup and The Melbourne Cup.

Our horse racing betting guides are in production.

Tennis

Daily tennis matches are a dream for bettors, so we went ahead and listed what we think are the top sites for tennis betting, the top apps for betting on tennis, and of course the current tennis promotions and sign up offers.

We’ve also covered the four majors in detail – so you can find the best deals – The Australian Open, The French Open, Wimbledon & The US Open.

We’ll be publishing some tennis guides and strategies for betting shortly.

Golf

It might not be everyone’s most exciting sport, but Golf brings about plenty of betting attention. So you can expect to see our ideal golf betting sites here, golf betting deals on this page, and our golf bet apps over here.

We’ve also extensively previewed and listed the offers for The Ryder Cup, The Masters, The Open Championship, and The US Open.
