All gambling sites are giving faucet money to try their games and not a to make a money out of it. So don't expect from any gambling site free money to withdraw every day. After trying their game then you have to play with your money to check your luck. But remember in gambling losing chances are more so don't over spend which you can't afford to lose.
If the presence of faucet is just to test the game, why does the faucet's value always increase every time we reach a certain level? 100 or 200 satoshi will be enough to test the game.
If it's to reward active users then there are some better ways than faucet.
