FreeBitco.in is one of the oldest faucets for Bitcoin still running, with several options to earn besides claiming.
You can claim Bitcoin once each hour, and for each claim you can earn from a minimal amount (at 0.00000012 BTC right now) up to a very respectable value (at 0.0297 BTC right now). Claiming values fluctuate alongside BTC value on the markets, so if the value goes down on the markets you can claim more and when it goes back up you actually earn more.
A High-Low game is available if you're into multiplying Bitcoin, but be careful not to lose what you have accumulated.
Also once you reach a threshold of 0.0003 BTC you can either withdraw (can activate auto-withdraw or do it manually) or leave your accumulated amount to earn 4.08% anual rate interest (you also earn 25% of your referrals' interest).
There's also a lottery for which you get tickets each time you claim, and you can exchange points for claiming boosts, items or gift certificates.
You earn 25% of referrals' base claims.
