About Dice App: Free Browser Dice Roller
Dice-app.com is a free online dice roller. Pick a die, pick how many, and roll. It covers d4 through d100 with modifiers and roll history, works on a phone, and needs no account. Every roll is generated on your own device and nothing is sent to a server.
Why this exists
I got tired of the alternatives.
Search for a dice roller and you land on a page that takes four seconds to load, pushes an ad banner over the roll button, or asks you to install an app to do something a web page can do in a few lines of code. Some of them want an account. For rolling a d20.
So I built the version I wanted: one page, loads fast, rolls immediately, works the same on a phone at a kitchen table as it does on a laptop. No ads, no signup, nothing to install. If you’re mid-combat and the DM is waiting, you shouldn’t be dismissing a popup.
The site has grown a set of reference pages around the roller, since half the questions people search for are rules questions rather than roller questions. Dice notation and the rules for common dice games came out of that.
How the rolling works
Your browser has a built-in random number generator. The roller calls it, maps the result onto the number of sides you asked for, and shows you the faces. That’s the whole mechanism. There’s no server involved in producing a number, no queue, and no round trip, which is why the result appears the instant you click.
It’s not a physical die, so it can’t be shaved, weighted, or cocked against a book. For a home game it behaves the way a fair die does. It is not built for cryptographic use or for anything involving money, and I wouldn’t recommend it there.
Privacy
Rolls never leave your device. There’s no account to create, no roll log stored anywhere, and no record on my end of what anyone rolled or when. I can’t see your rolls, and neither can anyone else, because the data doesn’t exist outside your browser.
I look at aggregate traffic numbers to know which pages are worth improving. That’s it.
Who made it
I’m Tim. I build small web tools and write about them at timmyships.com. This one started as a weekend project and kept going because people kept using it.
If something’s broken, a rule on one of the pages is wrong, or you want a die type that isn’t here, email info@dice-app.com. Corrections to the game rules pages are especially welcome, since house rules vary wildly and I’d rather document what people actually play. Start with the dice roller if you just came here to roll something.
FAQ
Is dice-app.com really free?
Yes. No account, no paid tier, no app to install, and no feature held back behind a signup wall. The site costs very little to run because it’s static pages and the rolling happens in your browser rather than on a server I have to pay for.
Do you store my rolls?
No. The roll is produced on your device and stays there. Roll history is saved in your own browser’s local storage, so it survives a page refresh but never leaves your device. There’s no roll log on any server, so there’s nothing for me to store, sell, or hand over.
Can I use these dice for a real tabletop game?
That’s what it’s built for. Plenty of groups use it when someone forgot their dice bag or the game is running over video. It won’t satisfy anyone who wants the sound of dice on a table, which is a fair objection and one I can’t do much about.
How do I report a mistake on the site?
Email info@dice-app.com with the page and what’s wrong. Rules pages are the most likely place for an error, since dice games pick up local variations and the version I documented might not be the version your family plays. I read every message.
