There are 2 kinds of No Deposit bonuses: No Deposit Free Spins and No Deposit credits (cash).
When you sign up with an online casino, you will get a certain amount of free credits to play with — No Deposit free cash. The amount you get will be from $5 to $50. You can use the credits to play any casino game unless the terms and conditions say otherwise. Don't forget that the credits are not real money and cannot be withdrawn. They are always subject to a wagering requirement- this means you have to play through a certain number of credits before you can withdraw any winnings.
No Deposit Bonus casinos give their players a number of Free Spins on one of the most popular casino games — online pokies. Gamblers usually get 10-100 No Deposit free spins, which they can spend playing online pokies from a list of eligible bonus games.
Don't forget about the wagering requirement. When it comes to free spins, the wager will apply to the number of casino credits that players win after using the free spins.
