It will take a lot of bets though, but if you are using the auto bet settings, it should be very possible.
actually it is neither possible nor practical to do that.
faucet payment is from 200 to 1000 satoshi max and using martingale even with 1 satoshi starting amount ends badly because you can not handle losing streaks at all. with a simple 6 or 7 losses your bankroll is empty and the biggest losing streak that i had in dice is about 30ish reds in a row!
