You first need to create an account at a licensed online casino. Then, deposit funds to your account through an accepted payment method. Choose the slots game you want to play, start it up, and set the size of the bet. Now, you just have to press the spin button to play one round.
All you have to do is fill in the details as quickly as possible. You may also be asked if you would like to receive the new player bonuses. Some online casinos also prompt you to select a preferred banking method and enter your card details.
