Android Marshmallow (included games)

Developer Google has a tradition of including Easter Eggs with the release of each Android operating system. For Marshmallow (Android 6.x) they included a variant of the mobile game Flappy Bird.

Instead of tapping repeatedly to keep a bird in the air as it passes through narrow openings between pipes, players now control the Android mascot as it is maneuvered between large marshmallows on sticks. The game keeps tracks of the score for each passed marshmallow and there is only one life. When colliding, the level has to be restarted. The level design, direction and colours, as well as the time of day, is randomized for each session.

The game is accessed by going to the about section in the settings of the phone or tablet, and tapping the Android version repeatedly.

The game is still included in Android, hidden away in the activities. You need an "activity launcher" to access the game In later versions.
