I only used $10 for starting money and from that $10 it could keep changing depending on how long I played the slots game. But I didn't spend that $10 right away in one day but I left a few dollars in my account to play again in the future.

The initial amount of money depends on the individual gambler and I am the type of person who does not make large deposits. So I think $10 is enough. Maybe you can try with $10 and see the result.
