Coin for Luck

A coin you can feel. Swipe it up off the glass, watch it fall, read the answer. Real physics, no accounts, no ads, no data.

Make a wish. Swipe the coin up. Watch it decide.

Coin for Luck is a coin, not a fortune teller. It doesn't read your wish and it doesn't know your future. Every flip is a fair, independent 50/50 — your wish doesn't lean on it, and neither do we.

What makes it worth watching is the fall.

HONEST PHYSICS The coin doesn't play an animation. Its flight is solved from the physics of a real coin: free rotation of a thin disc, the wobble that comes from where your finger caught it, three bounces off the glass, then the spin-down of a coin settling on its edge — the same rising rattle you hear on a table. Nothing loops, and no two flips look alike.

IT LANDS ON ITS EDGE Rarely, and on purpose. That's the third thing a real coin can do, and here it happens too. It isn't a glitch and it isn't a sign. Flip again.

YOU THROW IT YOURSELF Swipe up from the lower half of the coin. A strong flick sends it high, a small one barely hops. Press its upper half to slide it around the glass. It stays where it lands — the table is yours, not a screen that resets.

SOUND AND TOUCH Every strike you hear was calculated, not recorded: the metal's inharmonic voice, the click of the rim on glass, the rattle of the disc settling. Haptics run on the same schedule, so what you feel and what you see can never drift apart.

DRAWN FROM SCRATCH The coin, its eagle, the relief, the gold, the glass table — all made for this app. It is not a scan or a copy of any real coin or currency.
