Quite a number of online casinos give players free play bonus on the slot machines. This way you get a chance to try out all the great online slots games without making a purchase. This is a limited time promotion that is currently running on several online casinos but could end at any time. We suggest you take advantage of the promotion right away before it is no longer available. I want to inform you that no online casino is currently giving the free play bonus any longer. It was a nice promotion where players received a high amount of credits to play with for free but it was hard to actually win money, plus was limited to how much players could claim with a deposit. Instead they have changed to deposit offer only.
