As the name suggests, ‘free play’ is when you can play a casino game for free, without having to deposit any money. This is also known as ‘demo mode’. Free play mode is a great way to try out a new game, to see if you like it. Then, if you want to, you can switch to the real-money version. So, you can play this game in demo mode at a good online casino, before you have to deposit your own money.
