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.
It doesn't matter if you're in Poland, the UK, the US, Brazil, Portugal, Spain, Germany, or anywhere else. As long as you use a high-quality VPN, you can play on bet365 from anywhere in the world.
