The winnings from free spins bonuses had no risk involved, and the players are often shown how these winnings were converted into a no deposit bonus that has its own set of rules. Someone who has gotten a free spin from a bonus has to be aware that they cannot instantly withdraw that money. They need to read the rules for the site because those rules could change from one company to another. Some companies will not allow players to withdraw any money until it has been bet again, or they might allow the player to withdraw a percentage as a show of good faith.
