345Dice: Instant 3D Dice Rolling, Built with Integrity by 345tool
There’s a moment at every game table — real or virtual — when someone reaches for a dice, shakes it, and lets it fly. That tiny pause, the clatter, the collective lean-in to see the result: it’s a ritual as old as gaming itself. 345Dice was built to capture that exact moment and bring it to the browser. No account. No download. Just a handful of beautifully rendered 3D dice that roll, tumble, and land with the weight and unpredictability of the real thing.
It’s the second tool from the 345tool Team, and like everything we build, it was made to do one thing and do it with integrity.
Why We Built 345Dice
We didn’t set out to reinvent dice. We set out to make them available — instantly, fairly, and without compromise. Most digital dice tools fall into two camps: flat, lifeless number generators that feel nothing like rolling, or bloated apps that demand your email before letting you test a single roll. 345Dice sits in neither.
We wanted a tool that felt physical and playful, ran entirely in your browser, respected your privacy, and worked on every device without a single extra step. Behind the scenes, 345Dice uses WebGL for real-time 3D rendering, a cryptographically secure random number generator for true fairness, and a lightweight architecture that keeps everything local. The dice spinning, bouncing off the virtual tray walls, settling into their final positions — it’s all happening inside your own device. Nothing gets sent anywhere.
A Roll That Feels Real
A lot of digital tools are measured by what they do. 345Dice is measured by how it feels. The dice here don’t just flip to a number; they roll, tumble, collide with each other, and ricochet off the tray boundary. There’s a subtle weight to them — a brief moment of suspense before the final result locks in — that mimics the physical act of shaking a dice cup and letting it go.
We paid attention to the details: the matte finish on a d6, the satisfying spin of a d20 that takes just a fraction longer to settle, the way multiple dice scatter naturally rather than stacking neatly. It’s the difference between “getting a number” and “taking a roll.” If you’ve ever played a game where the dice felt like an afterthought, you’ll notice the difference immediately.
The Complete Polyhedral Set, Ready When You Are
Whether you’re deep into a Dungeons & Dragons campaign or just settling a friendly board game dispute, 345Dice gives you instant access to every polyhedral dice you need:
d4 — The pyramid, essential for magic missiles and dagger strikes.
d6 — The classic cube, board game staple and RPG workhorse.
d8 — The octahedron, perfect for tactical weapon damage.
d12 — The dodecahedron, niche but devastating in the right hands.
d20 — The icon. Attack rolls, saving throws, the roll everyone watches.
Select one die or a handful. The tool adapts instantly. There’s no bag to rummage through, no lost dice under the couch, and no arguments about whether someone’s “lucky” dice are actually balanced.
Flexible Quantities for Every Game
345Dice isn’t locked into one configuration. We designed presets that match how people actually play.
The default 2-dice roller is perfectly tuned for classics like Monopoly, Settlers of Catan, and Backgammon, showing total sums instantly so no one has to do post-roll math.
For tactical skirmishes or Yahtzee, jump to 3, 5, or 10 dice with a single tap. Liar’s Dice players get exactly what they need: quick, private rolls that can be passed around or viewed on a shared screen, no physical cups required.
These shortcuts don’t just save time — they make 345Dice feel like a natural extension of your game night rather than a piece of software you have to fight with.
Built for Privacy, Not for Data Collection
Like CounFlip before it, 345Dice was architected with privacy as a structural feature. The entire physics engine, the random number generator, the 3D rendering pipeline — it all runs inside your browser. We don’t use cookies. We don’t track your rolls. We don’t have a database that logs what you did. Close the tab, and the session is gone.
This isn’t just a policy statement; it’s a performance choice. Because no data travels to a remote server, 345Dice loads instantly and responds with zero network lag. For teachers demonstrating probability in a classroom, that means students can roll hundreds of times with total data privacy. For competitive players, it means every outcome stays private until you choose to share it.
The Truth About Fairness
“Is this random?” That’s the question every dice tool gets asked. Here’s the honest answer for 345Dice.
The randomness comes from two sources working together. First, a cryptographically secure random number generator produces unpredictable seed values — the same standard used in security applications. Second, a real-time physics simulation adds an organic layer of chaos: gravitational simulation, object collisions, and tray-wall bounces all influence the final result. Together, they make outcomes mathematically fair and functionally impossible to predict or manipulate.
We built it this way because we want competitive players to trust the tool, and because we don’t want anyone — including us — to be able to game the results.
Ready on Any Device, Zero Friction
345Dice was engineered to work wherever you are. The interface adapts seamlessly to desktops, tablets, and smartphones, with large, finger-friendly tap targets and smooth 60fps animations that won’t drain your battery. There’s no app to download, no registration form to skip, and no paywall waiting to ambush you after your fifth roll.

Frequently Asked Questions
What is 345Dice, and how do I use it?
345Dice is a free, web-based 3D dice roller created by 345tool. Available at dicebrew.com, it lets gamers roll a variety of polyhedral and standard dice directly in their browser with realistic physics — no installation needed.
What’s the difference between “dice” and “die”?
Traditionally, “die” is singular and “dice” is plural. In modern conversational English and gaming communities, “dice” is often used for both. 345Dice handles all terminologies seamlessly — roll one die, roll two dice, we’re not picky.
Can I use this for classic board games and betting games?
Absolutely. The default 2-dice setup is perfect for Monopoly, Backgammon, and similar games. You can scale up or down based on your specific rules.
How does 345Dice handle D&D or Pathfinder mechanics?
Our polyhedral kit includes dedicated d4, d6, d8, d12, and d20 dice. Select your face count and roll multiple items simultaneously to resolve complex weapon damage or multi-target spell saves.
Is the roller truly random and fair?
Yes. 345Dice combines a cryptographically secure RNG with real-time 3D physics — tumbling, bouncing, and tray collisions add an organic layer of chaos that makes outcomes unpredictable and unriggable.
Do I need an account?
No. 345Dice is 100% client-side. No registration, no login, no subscription. All computations happen in your browser, giving you an anonymous, private, and lightning-fast experience.
Can I play Liar’s Dice or other multi-player party games?
Yes. The 5-dice and 10-dice presets are optimized for passing a phone around or sharing a screen, simulating hidden dice values for bluffing without physical props.
Meet the 345tool Team
We’re technologists, researchers, and builders working remotely across different time zones. Some of us write code. Some of us test AI tools until they break. All of us believe that good software respects your time and your intelligence.
We don’t have a fancy office or a PR department. We have a shared conviction that practical, well-made tools deserve to exist — and that the internet gets a little better every time one does.
Our editorial side also reviews the latest AI products, reading the documentation nobody else reads so we can write honest, practical guides that help real users find the right AI solutions. This blend of building and reviewing keeps us grounded: we know what great software feels like because we use it, test it, and build it every day.
What’s Next
345Dice is the second tool from 345tool, following CounFlip. We’re building a suite of single-purpose utilities that each do one thing well — instantly, privately, and without friction. More tools are in development, each following the same principles: pure client-side architecture, zero accounts, cryptographically fair outcomes, and an interface that gets out of your way.
We’re also continuing our deep-dive AI product reviews — testing the tools nobody else tests thoroughly, reading the documentation others skip, and writing guides that help real users make informed decisions in the rapidly changing AI landscape.
If you’ve got an idea for a tool that deserves to exist, or feedback on 345Dice, we’d love to hear it. The next tool in the 345tool lineup might be inspired by a conversation that starts today.
