Free spin casino is a great option for when you don't want to risk your own money. Free Spin casinos give you a certain amount of free casino money and a set amount of time that you use to play the games. The timer is usually 30 minutes or one hour. At the end of the timer any winning ABOVE the amount the casino gave you are yours to keep.
The free spin casino offers come in varying amounts, some casinos give you 200.00 to start while other give you up to 5000 credits. The amount of the free chips does not really matter as you can only keep your winning amount above your starting free spin balance. So spin away and hit that jackpot!
Remember to check out the casinos terms associated with any free spin bonus, especially play through requirements. Some may even require a small deposit to verify your identity and jurisdiction.
