A deceptively-simple mobile game in which players flap the odd-looking bird Faby between pairs of pipes by tapping the screen. It's notable for its removal from storefronts due to its addictive success, spawning numerous clones and imitators wanting to take its place.
A reboot of the 2013 smash hit, but with extra modes and characters, microtransactions, block chain/crypto features, and no involvement or blessing from creator Dong Nguyen.
