Another common online casino bonus is the free (or free bets) bonus. These are very common these days and a great enticement for players to sign up and make a deposit at an online casino. Free spins bonuses can be either no deposit bonuses or deposit bonuses. A free spin no deposit bonus will likely be something like 10-25 free spins at a particular game or online slots machine.
A deposit free spin bonus might be more like 100-200 free spins. Once you have made a deposit you will be allowed to access the free spin although the spins might be allocated with 20 spins upfront and the rest over a set number of days, like 20 spins a day over 9 days. Money you win from those spins will be yours to keep but only after you play through a certain amount. If you want to get a taste of what a particular slot machine is like before you actually put any money into the casino to play, no deposit free spin bonuses are a great opportunity to do so.
