We are talking about gaming platforms that allow users to play casino games without having to wager real money. The goal here is to have fun and socialize with friends.
Social casinos look and function in the same way as real money online casinos. Players can play slot machines and classic games like bingo, poker, and roulette. However, instead of betting real money, social casinos use virtual currencies and points.
You may have to deposit a certain amount of money first, but playing on such platforms does not mean that winnings are paid to a debit card.
If you want to play casino games without wagering real money I'll advise you stick to demo mode, where you don't have to deposit any money for the start but you tend to play with what's in there and as well can't account for losses,precisely like you said you can always have fun playing it with friends since you have nothing to loose after all. But for the likes of social casino I've not been involved in it whereas knowing how it works but there's no much difference with it compared to normal casinos that you tend to play some games such as roulette and the others.
