Log in to your Bet365 account and select the 'Sports' tab. Select the markets of your choice and add them to your bet slip. Make sure you have at least three selections, as this is the minimum required for an accumulator bet. Once you have added all your selections to your bet slip, select the 'Accumulator' option.
Open the Bet365 mobile app or visit the Bet365 website using your mobile browser. Click on the "Log In" button and enter your username and password. Once you're logged in, you'll find the Bet365 Casino section in the app's or mobile site's main menu. Tap on it to access the wide range of casino games.
