Many online casinos offer the option to play online casino slots as a demo first, where you play the game on a fictional budget and then switch to a paid version of the game, at least, a version where you actually gamble with real money. Gambling for money is of course also possible directly in the online casinos.
The main advantage of a demo is the possibility to first see whether an online slot actually suits you, whether you fully understand its rules and whether you think you can have a nice prize.
When you gamble for money, there is logically the possibility of losing money quickly. For example if you do not understand the rules correctly and therefore make unnecessary mistakes during play.
Before you can gamble for real money, you need to transfer money from your bank account to your game account. This is very easy at most online casinos by using, for example, credit and debit cards, which you may know from other online stores.
In a physical casino it works slightly differently, there you first buy an entrance ticket and then you can buy chips for the different games at the checkout. In physical casino you can put cash in the slot machine to play, without having to buy chips first.
When you have deposited money into your game account you can start playing for real money, by betting on one of the many online casino slots, the bingo, a table game or for example a sport match.
Make sure that a bet is also binding and cannot be canceled during a round. So when you lose, you lose the money you bet. This of course also applies if you play with chips in a physical casino, once bet means that you can not take back the money. An exception to this rule is the bets on which you can bet live during a sports match. It is possible to take back part of your bet before the end of the game, sometimes this will be at a loss and other times at a profit, depending on the course of the game.
