Online Dice Roller
Every die you'll ever need
Roll up to twenty dice at once with 4, 6, 8, 10, 12, 20 or 100 sides — covering board games with lost dice, probability lessons, and the full D&D set. The big number is the total; the breakdown underneath shows each individual roll so nobody disputes the maths.
Rolls use the browser's random number generator, which is more uniform than any physical die. For maths classes, rolling 2d6 a few dozen times and tallying the results is the fastest way to make the bell curve visible. Need a random number without the dice metaphor? Try the random number generator.
Frequently asked questions
Is the dice roller free?
Yes — it's completely free, with no sign-up and nothing to install. It runs entirely in your browser and is free for any school or home use.
Do I need an account or internet to use it?
No account is ever required. The tool loads in your browser and keeps working even if your connection drops mid-lesson; any list you enter is saved locally on your own device, not on our servers.
