These include deposit limits, time outs, cooling off periods and even self exclusion if required. Make sure you read what are the minimum and maximum amounts from the casino site’s help section, so that you avoid any nasty surprises later on.

However, if a site offers the ability to test out real money games for free, we’ll definitely rate it higher. Oshi Casino is one of the most generous, offering new players up to €4,000 as a match deposit, so if the amount is really low this affects our score.
