And even if I try to use more faucet I don't see any options. Because I don't know any faucet that gives more than 250 per 15 mnt with 100% guarantee.
I know one.
http://btc25.net/ (ref) pays at least 525 satoshi every 25 min.
And you have chance to win more (up to $25). I won 0.00009898 BTC 7 times in the last 5 days.
Of course, it's a wasting of time, but sometimes it's just funny:)
