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.
At first I was thinking you are talking about the demo mode that comes with some slot games in some casino. I have seen casino where you get to play the same slots game for fun as per the games are loaded with a certain amount in which the user gambler first for fun to test out the games but after reading this thread I now know you are saying totally different from what am thinking.
