http://www.cryptocoinsnews.com/do-free-bitcoin-sites-work/Google the phrase free bitcoin and you wont be disappointed with the number of results. What you will be disappointed with however is the nature of the sites claiming to offer free bitcoins. As the old saying goes: Nothing in life is free.
What these sites actually do is require you to perform time consuming tasks for a few measly satoshi (0.00000001 Bitcoin) which you will probably never see in any useable form as the sites have payout minimums that are impossible to reach. I decided to trawl through some of the top results for this search in an attempt to actually use them.
