Autobet is a feature that many gambling websites have that allows you to set your bets and other features to automatically run for you. This means that you do not have to do or set anything every time you want to play.
To set an Auto Cash Out request, simply click on the cog icon to the right of the Cash Out button, enter the threshold that you would like to set in the 'If the value reaches' section and then select 'Create Rule'.
