Bumpy

Tap or press space to flap. Slip through the gaps.

How to play Bumpy

Tap, click or press the space bar to flap. Each flap pushes the smiley up; gravity pulls it down. Slip through the gaps between the green pipes. Hit a pipe, the ground or the ceiling and the run is over. The score counts every pipe you pass. Your best score is saved on this device.

Tips

Short, light flaps work better than mashing the button
Aim for the centre of the gap, the smiley falls fast once you stop flapping
Find a steady rhythm on the early pipes, the speed never changes
On mobile, tap anywhere on the sky to flap, you do not need to hit the smiley

About Bumpy

Bumpy is a colorful take on Flappy Bird, the wildly popular one-button arcade game by Vietnamese developer Dong Nguyen that ruled mobile app stores in early 2014. The mechanic is dead simple, the difficulty curve is famously cruel and the satisfaction of a fresh personal best is hard to beat. Our version uses a friendly yellow smiley, sky-blue cartoon clouds and bright green pipes. Free, no login, instant retry.
