This is just my opinion base on my experience:

wolf.bet is the usual, already seen thousand times website with a game that you will never win.

I saw many of these websites and they all works the same way:

- First bet = always win
- next bets: you bet high, it comes low. You bet red, it comes black and so on.

I also cound't find the faucet anywhere.

Last thing that made me think this site isn't legit:

in order to be able to chat, you must have placed 1000 bets! Wtf?

In conclusion: I wouldn't waste a single satoshi.

Just my opinion
