Is this online dice roller fair?
Every roll uses JavaScriptβs built-in pseudo-random number generator, which is more than
enough for normal games and classroom work. Each side of the die has the same chance to
appear. If you want to explore the math behind dice probability in detail, open our
Probability Calculator in another tab and compare
real roll data with expected results.
Dice roller vs. physical dice β when to use each
Physical dice feel great in the hand and are part of the tabletop experience, but they can
get lost, roll off the table or be biased if theyβre worn out. This online dice roller is
ideal when you are:
- Playing online with friends in different countries and need visible, shared results.
- Running a game session on a laptop or tablet and want faster rolls.
- Teaching probability and need hundreds of rolls without collecting dice.
- Travelling and forgot your dice at home.
