It looks interesting. It looks that reward system will be similar like on moonbit.co.in. 50 satoshi every 5 minutes is good reward. In one hour it's possible to earn 600 satoshi.
50% referral commission is generous and I also like idea of daily claim bonus. Daily loyalty bonus is also good thing. Loyalty lifetime bonus sounds to good to be true.
Chatbox is useful thing I think.
2 level affiliate bonus good for users, but it can be hard to pay, it can be too expensive for faucet.
Lottery - lets say that ticket costs 1000 satoshi. 50% is fee, so 500 satoshi goes to prize pool. Another users buys ticket - another 50% as fee and 500 satoshi to prize pool. So, the lottery prize is 1000 satoshi and if user win, he only receive 1000 satoshi what he spent for the ticket.
I think for faucet is also important - low payout treshold, or make payments bia microwallets like Faucethub or ePay.
