How this online dice roller works
Choose how many dice to roll and how many faces each one has, then press Roll the dice. The page asks your browser for a secure random number for every die, so each face is equally likely. The tumbling animation is just for fun. If your device is set to reduce motion, the result appears straight away.
Which dice should I pick?
- 1 x d6: Ludo, Snakes and Ladders and most family board games.
- 2 x d6: Monopoly and Carrom-style score games. The total 7 comes up most often because six pairs make it.
- d20: role-playing games and quick "high or low" challenges.
- d4, d8, d10, d12: game masters and maths classes exploring probability.
Probability in one minute
With one fair d6, each number has a 1 in 6 chance. With two d6 there are 36 possible pairs, so a total of 2 or 12 appears only once in 36 rolls, while 7 appears six times. Roll a few hundred times with your class and compare the totals to see it for yourself.

Frequently asked questions
Are the dice rolls fair?
Yes. Every roll uses your browser's secure random generator, so each face has exactly the same chance. The shaking animation is only for fun; the result is decided when you press Roll.
What does d6 or d20 mean?
The number is how many faces the die has. A d6 is the normal cube used in Ludo, Monopoly and Snakes and Ladders. A d20 has twenty faces and is popular in role-playing games.
Can I roll more than one die?
Yes. Choose 1 to 6 dice. You will see every die and the total. Rolling two d6 gives totals from 2 to 12, and 7 is the most common total.
Why do I get the same number twice in a row?
Each roll is independent, so the dice have no memory. Repeats and streaks are normal in random results and do not mean the dice are unfair.
What is the highest total record?
For each dice setup, such as 2d6, the page remembers your highest total on this device and lets you share it as an image.
