There are 3 major sites that give free Satoshis (Bitcoin units) every 5 minutes by just simply entering the captcha to prove its a human transaction. Good thing about these sites are that they use common CoinPot so that you dont have to individual meet the minimum requirement to withdraw your Bitcoin. Felt good?

Bitfun - Nice way to accumulate Satoshis every 3 minutes.
MoonBit - Very easy to use interface. Gives daily bonuses and Mystery bonus
BonusBitcoin - Minimum time to wait to claim you Satoshis is 15 minutes but worth it anyways
