Frequently asked questions
Is the coin flip actually 50/50?
Yes, each flip draws from the browser's cryptographic random source, so heads and tails are exactly equally likely and past flips have no effect on the next one.
What dice can I roll?
The standard tabletop set: d4, d6, d8, d10, d12, d20, and d100, up to twenty at once with the individual results and their total shown.
Why did I get heads five times in a row?
Streaks are normal in fair randomness: in 100 flips there is about an 81% chance of at least one run of five. The tally below the coin lets you watch the ratio settle toward 50/50 over many flips.
