User summary: Flappy48 is a game that combines the concepts of both Flappy Bird and 2048. Flappy48 can be played in a browser (with the Unity web player installed) or downloaded via the Google Play store, and has your little 2 tile leaping between pipes and bumping into other numbers, which will combine if it's a multiple of two. The goal is to reach 2048, but the game can be played continuously after.
