Best Betting Sites and Online Casinos: How to Compare Them Before You Deposit

A quick way to compare odds is to look at the same market, such as a Premier League match result, across a few sites. If one is consistently shorter, that site takes a bigger margin from you. Our odds converter is useful if you're comparing formats such as decimal, fractional and American, and our list of the best odds betting sites is a good starting point.

How to read online casino reviews

Online casino reviews are only as good as the evidence behind them. Here is how to tell a useful review from a sales page.

A good review will:

•       Say how the writer evaluated the casino, including what was checked and how.

•       Name the licence and the company that operates the site.

•       Cover the downsides as clearly as the upsides. Every casino has some.

•       Explain bonus terms in plain language, with a worked example.

•       Show a "last updated" date, since terms change often.

A weak review will:

•       Call everything "the best" without giving a reason.

•       Mention the bonus in the first line and never discuss withdrawals.
