Heads or Tails Marble Race

Race Heads against Tails

On your first visit, Heads and Tails are already entered once each. Choose a map and press Start Race. Read the first finisher as the result. Later visits restore the entries you last used on this page.

How It Differs from a Coin Toss

Two labeled marbles travel through a simulated obstacle course. This is a visual coin flip alternative, not a simulation of a physical coin. The course and marble interactions affect the result; exact 50/50 odds are not guaranteed.

Play a Series

For a best-of-three or best-of-five game, agree on the rules before starting and keep your own tally. Use Race Again after each finish. The app displays each race result but does not keep a series score.

Change the Options

You can replace Heads and Tails with other choices or add more entries. Use Reset to edit the list. Each tool keeps its own saved setup, so edits here do not replace your Yes or No list.
