The addictive game that was at the top of iPhone and Android app downloads disappeared from app stores on Sunday. "I am sorry 'Flappy Bird' users, 22 hours from now, I will take 'Flappy Bird' down," developer Dong Nguyen tweeted on Saturday. "I cannot take this anymore."

People who still want to play Flappy Bird are still searching for it on iOS and Android and the clones are now rising to the top. Some are so shameless (Happy Poo Flap) it is ridiculous.
