* No registration
When you click 'New game', you can play immediately, you will be redirected to a play URL,
that URL is like your password so please save it in a safe place,
whatever person with that URL could play with your money.
I don't know about the other players, but this form of registration seems extremely dangerous to me. It is possible that for someone it will be a very convenient form of registration, but I am afraid to deposit money at an address that is not even secured with a password.
