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.
