About this tool
Every roll and flip uses the browser’s cryptographically secure random generator with unbiased sampling, so each face of the die and each side of the coin is equally likely — just like a fair physical die, and without the worry of a loaded one.
Use several dice for board games like Monopoly (2 dice), d20 for role-playing games, or the coin toss to decide who bats first in gully cricket. The tally shows how heads and tails even out over many flips.
Frequently asked questions
Is the online dice fair?
Yes. Each face has exactly the same probability, using crypto.getRandomValues.
Can I roll two dice for Ludo or Monopoly?
Yes — choose 2 dice; the total and each die are shown.
Why did I get heads five times in a row?
Streaks are normal in true randomness. Over many flips, heads and tails each approach 50%.
