Gatebeat

A servo arm feeds falling shapes into their matching bins. Tap a bin and the arm swings over to it — but the swing takes a moment, and whatever is riding the channel goes along with it.

Circles roll fast, squares drag, triangles tumble. Heavy pieces swing wide. Bins drain slowly, so cramming one makes it overflow. Do nothing and the piece loops back around for another try.

One 60-second run. One shared seed per day, so today's run is the same for everyone.

Controls: tap or click near a bin. Keys 1-4, or arrow keys / A-D. Space sends the arm back to the return loop. M mutes.

Colorblind friendly — every piece is marked by shape as well as color. No ads, no downloads, no external assets: every shape and sound is drawn and synthesized in code.
