CAPTCHA is a Completely Automated Public Turing Test to tell Computers and Humans Apart, to ensure that the response is only generated by humans and not by computerized robots.Simpler CAPTCHAs are easily breakable due to advancement in pattern recognition and machine learning algorithms.There are enhancement procedures making few CAPTCHAs harder to decode.This paper brings the concept of humanfriendly mini-game CAPTCHAs which is easier for the humans and difficult for the bots to break.
