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 OTBB 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.

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.
