Flappy Chicken

A small browser game with a chicken in HatchMath colors. Tap or press space to flap; clear the fence posts; don't hit the ground. The calculators are still the point of the site — this is just a thing to do while you're here.

Controls: tap / click / space to flap · M to mute · P to pause · R to restart

Why this exists

HatchMath is calculator-driven research for backyard flocks. That's the actual product. Flappy Chicken is a side toy — built in a single HTML file, plays in any browser, doesn't collect anything from you, and isn't why you came. If you're here for real questions about chickens, the links below get you back to work.

Real chicken questions


Single-file vanilla JavaScript, WebAudio synthesis (no asset downloads), localStorage for high score and mute preference. Source intentionally not minified — view-source on the iframe if you're curious. Not collecting anything; the chicken and the score live and die in your own browser.
