Are you determined enough to get flappin' ?! In Flappy Royale, all you do is right-click at a time to flap once. Customize your avatar and don't bump into obstacles (different heights & different distances) to survive to the very end of the course. Be sure to time your flaps so that you can rise and fall as you move across the screen.
