A dice roller you can trust for every roll
A dice roller should do exactly what a physical die does — produce a fair, unpredictable result — without the hassle of digging a d6 out of a drawer or hunting down a matching set for a home‑brewed D&D campaign. That's the entire idea behind randomdiceroller.com: a free, no‑download online dice roller that works instantly in any browser, on any device, for anyone who needs a random number between two limits and needs it right now.
Why people search for a "google dice roller"
Most of us have typed "google dice roller" into a search bar at least once — usually mid‑game, when someone forgot the dice or a phone is the only object within reach. Google's own quick answer box is handy, but it's limited to a single simple roll and disappears the moment you navigate away. This site is built as a dedicated alternative: a full random dice roller that remembers your last configuration, shows the odds behind every throw, and keeps a live history of recent rolls so you don't lose track of a session.
Classic dice roller 1-6, and everything beyond it
At its simplest, this is a dice roller 1-6 — click once and get a fair, uniformly random number from one to six, exactly like a standard cube die. But tabletop games rarely stop at a single d6. Dungeons & Dragons players need a d20 for attack rolls, a set of d6s for damage, and percentile dice for random tables. That's why the notation field accepts standard dice shorthand — 2d6, 1d20, 4d6, 1d100, or a custom expression like 2d6+3 — so any combination of dice count, number of sides, and modifier is one keystroke away. Presets sit right above the roller for the combinations people reach for most often, so a full campaign session never requires typing the same notation twice.
A virtual dice roller that's actually fair
Calling something a virtual dice roller only matters if the randomness underneath is genuinely fair. Every roll here is generated fresh in your browser using a uniform random distribution across the full range of the die, so a d20 lands on each face with the same 5% chance a physical, perfectly balanced die would give you — no server round‑trip, no seeded results, no hidden bias toward "nicer" numbers. Because the math runs locally, results appear the instant you click or tap, which matters when you're mid‑turn at the table and don't want to wait on a spinner.
Built for the moment, not just the roll
A dice roller online is only half useful if it can't tell you what a "good" roll actually looks like. Alongside every throw, this tool calculates the expected total for your current notation, the chance of clearing a meaningful threshold, and a live probability distribution across possible outcomes — so you can see, before or after rolling, exactly how lucky (or unlucky) that throw really was. A running history keeps the last several rolls visible without cluttering the screen, and everything resets cleanly with a single "Clear history" click when you start a new session or a new game.
Free, fast, and available in ten languages
There's no sign‑up, no install, and no cost to use this random dice roller — it's designed to be as frictionless as reaching for a physical die. It works equally well as a quick dice roller online for a single yes/no decision and as a dedicated companion for a full tabletop RPG session, complete with keyboard support (press space to roll) and a dark mode for late‑night games. The interface is also available in English, Spanish, French, Portuguese, Russian, Arabic, Urdu, Hindi, Bengali, and Simplified Chinese, so the same fair, transparent dice experience is accessible to players around the world.
Common questions
Frequently asked questions.
Is this dice roller free?
Yes. This dice roller is completely free to use, with no sign‑up, no download, and no hidden paywall. It runs entirely in your browser, so you can roll as many times as you like at no cost.
What is the best online dice roller?
The best online dice roller is a fast, fair, and simple one — no clutter, no ads blocking the roll button, and randomness you can trust. This tool aims to be exactly that: instant results, transparent probability, standard dice notation support (like 2d6+3), and a live roll history, all free and usable on any device.
What types of dice can I roll?
You can roll any standard die from a d2 up to a d1000 using dice notation. Common tabletop dice like d4, d6, d8, d10, d12, d20, and d100 (percentile) are all supported — just type the notation, such as 1d20 or 4d8, or use one of the quick presets above the roller.
Can I roll multiple dice at once?
Yes. Enter the number of dice before the "d" in the notation field — for example, 4d6 rolls four six‑sided dice at once and adds them together, and 2d6+3 rolls two six‑sided dice and adds a +3 modifier to the total. Up to 20 dice can be rolled in a single throw.
How do I make a dice roller?
A basic dice roller only needs a random number generator that produces a uniform value between 1 and the number of sides on the die, typically using Math.floor(Math.random() * sides) + 1 in JavaScript. Building a polished one — like this site — also means parsing dice notation (e.g. 2d6+3), calculating expected values and odds, and rendering results clearly on screen.
How do I add a dice roller to Discord?
Most Discord servers already have dice‑rolling built in through bots like Avrae, Tupperbox, or the built‑in slash commands of RPG bots — typically triggered with a command such as /roll 2d6 once the bot is invited to your server. If you just need a quick roll outside of Discord, you can use this online dice roller in a browser tab and share the result in chat.
How do you play the "high roller" dice game?
High Roller is typically played by each player rolling a set number of dice (often 2d6 or 5d6) and comparing totals — whoever rolls the highest total wins the round. Variants add rules like re‑rolling ties, "busting" on certain combinations, or playing best‑of‑three; you can use the presets or custom notation here to quickly roll for each player's turn.
What is the best hosting for dice roller apps?
Because a dice roller is a lightweight, client‑side app with no database and minimal server logic, it's best suited to static hosting platforms such as Vercel, Netlify, GitHub Pages, or Cloudflare Pages — all of which offer fast global CDNs and free tiers well suited to a small, JavaScript‑driven tool like this one.
