Free Money
It’s hard to argue with this, even though free casino bonuses often are rather small. You’re going to play online casino games anyway, why not have some free money to play with? You play online casino games in the hopes that you’ll win money; bonus money is guaranteed as long as you meet the wagering requirement.

Opportunity to Try Something New
Perhaps there’s a new online casino site you’ve been interested in but haven’t been motivated to try. If you can find a great free casino bonus for that site, you have the perfect excuse to log on and check it out. Similarly, if there’s a game you’ve always been curious about, you can try to meet your wagering requirement learning that game, or you can use your bonus to learn that game once it has been cleared.

Wagering Requirements
The wagering requirement is significant; at least ten times the size of your casino bonus and probably more. If you don’t pick a game with a low enough house edge, you could run through your bankroll before you clear it, meaning you’ll have to deposit money or risk time expiring on your bonus. Try to find a game with a low house edge such as baccarat, blackjack, Pai Gow or craps (all with proper basic strategy) when clearing your free bonus. On the other hand, since the bonus is free, you can’t really lose anything.
