When you sign up for an account at the following casinos, they will give you free money to use in the slot machines. If you win, you'll be winning real money. If you lose, it was on the house anyway.

That, is a great way to test out an online casino.

These types of casino bonuses were popular at one point, and then they faded away with few casinos offering them. Now, the good times are rolling again with many online casinos offering free no deposit bonuses to attract new players.

Keep in mind that although the casinos will allow you to cash out after you have played the required time at the machines, they may put a cap on the maximum cashout. And yes, that's because once upon a time someone signed up at a casino, took the free money, hit the big jackpot, and lived happily ever after.
