I think it would be a while if someone wanted to just get money from the faucet. Now that it's 10 sats for every claim, anyway. You'd have to earn the transaction fee money first (even the low fee that will take a while is 7500 sats) and then start making whatever money you think you can get. The faucet is a nice incentive but at the end of the day, I think it's better to gamble those free sats and gain BFG tokens than spend 7500 sats minimum at withdrawing.
I don't think that there's money to be made with the faucet, even when it's giving extra. It's mainly for testing the cheapest games. You can't even afford of the more expensive slots with those. You would have to save a very long time.
