Coin Flip — Heads vs Tails, Settled by Physics

How to Flip a Coin with Marbles

Type "Heads" and "Tails" as your two entries, pick a map, and start the race. The marble that crosses the finish line first is your result. It's a genuine 50/50 — this coin flip is decided by a real physics simulation, not a canned animation with a predetermined outcome.

Better Than a Real Coin Toss

A real coin toss is over before anyone can enjoy it — and half the time the coin ends up under the couch. A marble race turns the same 50/50 odds into 30-60 seconds of suspense both sides can watch. Perfect for settling bets, choosing sides, kickoff decisions, or ending a "you pick" / "no, you pick" standoff.

Best of 3, Best of 5

Big decision? Don't settle it in one flip. Race again with the same entries — your Heads and Tails are saved between races — and run a best-of-3 or best-of-5 series. Each heads or tails rematch takes under a minute, and the drama builds with every race.

More Than Two Sides

A coin only has two faces, but your decision might have three or more options. Add as many entries as you need — "Pizza", "Sushi", "Tacos" — and this coin flip alternative becomes a fair multi-way draw. For a pure yes/no question, try the dedicated Yes or No Picker.
