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.

Last updated: Aug 14, 2026

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.

Rolling the wrong die type

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