Do I have to use real money to play?

[Roman]

Yes. The majority of online casinos allow you to wager or gamble on there platform or web interface only if money is involved.
You will still need to register an account with the majority of casinos, though, so keep that in mind. We only know of two exceptions: Bovada (US) and as well as Bodog. The majority of their games may be played without registering.
