The best online betting sites UK - CasinoHawks tips

When it comes to choosing your online betting site, first and foremost you should check whether or not the site in question is offering odds on the games you intend to bet on. This is becoming easier as time goes by, since all major online betting sites are now offering hundreds of betting options, across all sports and events.

Once you’ve identified a couple of sites that will be offering odds on the event that’s of interest to you, it’s worth checking out whether the site also offers in-play or live betting. This involves the possibility of betting on an outcome once the game has started, so you might take advantage of changes in momentum to make more accurate predictions. In-play betting offers many other advantages; the odds keep changing and may turn more in your favour, and there will also be additional betting options depending on what happens during the game, which will make your betting experience much more varied and exciting!

Of course, another factor to look out for when identifying the best online betting sites for the UK are the odds on offer; try to find a betting site which offers reasonable and value odds, and make use of an odds comparison site to try and determine the most favourable ones for a particular game. To do this, you need to look at what is known as ‘implied probability’; essentially, you have to identify those odds whose implied probability is less than what you think the actual probability is. This means that according to you, the online betting site considers that a team is less likely to win than you think it actually is, and therefore offers high paying odds if you back that team.

Last but not least, another factor we recommend looking out for, and which we shall be examining in more detail below with regard to our recommended betting sites, are the offers or promotions which online betting sites are running, and which are UK players may start taking advantage of as from today.
