🐦 Flappy Bird

How to play

A bird holds its position across the screen while gravity pulls it down at a constant 0.45 pixels per frame squared. Each flap sets its upward speed to 8, so staying airborne is a matter of tapping at the right moments rather than holding anything down. Pipes scroll in from the right every 1.6 seconds with a 140-pixel gap at a random height, and the run ends the instant you touch a pipe, the ground or the top of the screen.

• Click the play area — flap once. Clicking while no run is in progress starts one.
• Space — the same flap, from the keyboard.
• Start button — starts a run when idle, and flaps while one is under way.

Scoring

You get 1 point for every pipe whose right edge passes behind the bird, and nothing else scores. The current score is drawn across the top of the play area and repeated in the Score readout. The Best readout tracks the highest score of your session; it lives in the page, so it resets if you reload. Difficulty never changes, because pipe spacing, gap size and scroll speed are all fixed.

Tips

• Aim at the lower part of each gap. A flap climbs fast, and it is easier to add height than to shed it.
• Tap at a steady rhythm rather than reacting to each pipe. The fall is constant, so a constant tap rate holds a constant altitude.
• Two quick flaps in a row send you up sharply and are usually too much. Let the bird level off before the next one.
• The ceiling kills you just as the pipes do, so avoid climbing hard when the next gap is already near the top.
