Free Coin Flip & Dice Roller
Flip a coin or roll dice, fairly.
What is the Coin Flip & Dice Roller?
No coin in your pocket, no dice in the drawer — but a decision to settle or a game to keep moving. A quick, fair random result is all you need, and it shouldn't require rummaging around.
This tool flips a virtual coin or rolls any number of dice with genuinely fair, random outcomes, right in your browser.

What does this tool do?
In coin mode it flips heads or tails and keeps a running tally; in dice mode it rolls the number and type of dice you choose.
Every result uses your browser's random generator, so each side of a coin and each die face is equally likely.

Common mistakes to avoid
Expecting past results to matter
Fix: Each flip and roll is independent — streaks don't change the odds.
Using it for high-stakes fairness

Rolling the wrong die type
Fix: Pick the sides your game needs (e.g. d20 for RPGs).
