Here’s a list that I compiled of all of the places you can get free Bitcoins (sometimes known as a "Bitcoin faucet").
So, you want free bitcoins?
Here you go then:
The Bitcoin Faucet (requires a Google account)
Paperco.in Faucet (Scan a QR code to reveal a MtGox code for 0.0007 BTC.)
Nakabot’s Bitcoin Faucet (Tor Hidden Service) (NakaBot pays out a portion of its winnings in 0.001 increments.)
Dragon’s Tale (A casino site, but gives out small amounts for free that you can use to gamble with or withdraw to your own Bitcoin wallet.)
Seals with Clubs (Seals has a free poker tournament every hour with a .05BTC prize. There are larger free tournaments from time to time.)
