About the Coin Flip / Dice Roller
Flip a coin for a quick decision, or roll as many dice as you need — d4, d6, d8, d10, d12 and d20 are all supported, which covers most board games and tabletop RPGs. Results come from your browser's secure random number generator, so every side has a fair chance.
Frequently asked questions
Is the coin flip really random?
Yes. It uses crypto.getRandomValues, the same secure random source used for password generation, rather than a simple pseudo-random function.
Which dice can I roll?
d4, d6, d8, d10, d12 and d20, in any quantity — useful for Dungeons & Dragons and other tabletop games.
What does "d20" mean?
The number after "d" is how many sides the die has, so a d20 is a 20-sided die that gives a result from 1 to 20.
