About this tool
Roll virtual 3D dice with realistic physics animations. Supports multiple dice types from D4 to D20.
The 3D Dice Roller throws between 1 and 10 dice of any standard polyhedral type — D4, D6, D8, D10, D12 or D20 — and totals them for you. Each face is drawn independently with JavaScript's Math.random(), mapped to a result as Math.floor(Math.random() × sides) + 1, so every face on the die is equally likely. The roll plays as an 800 ms CSS tumble — a bounce plus a random rotation of up to 720° — with the dice cycling through random faces before they settle; D4 and D6 land as classic pip faces, while D8 and larger show the rolled number. Everything runs as client-side React in your browser: no account, no network request while you roll, and nothing saved about your results.
Open Dice Roller (3D) on AltFTool — it loads instantly in your browser.
Pick a die type from the button row — D4, D6, D8, D10, D12 or D20.
Set how many dice to throw with the minus and plus controls, anywhere from 1 to 10.
Press Roll Dice. After the 800 ms tumble the faces settle, the individual results and total appear below, and the throw is added to your roll history.
D4, D6, D8, D10, D12 and D20 are each one tap away, and the counter runs from 1 to 10 dice per throw. Dice are tinted from an eight-color palette so you can tell them apart in the results row.
Each die is an independent draw computed as Math.floor(Math.random() × sides) + 1 — a uniform integer between 1 and the number of sides, with no weighting and no memory of what came before.
The individual faces and their sum appear the moment the animation ends, and the last 20 rolls stay listed with die type, dice count, every result, the total and a timestamp.
The roller is entirely client-side. It makes no network calls while you roll and writes nothing to your device, so it works from the second the page loads.
Yes — each die is an independent draw from JavaScript's Math.random(), scaled with Math.floor(Math.random() × sides) + 1, so all faces are equally likely. Math.random() is a fast pseudo-random generator rather than a cryptographic one; if you want crypto.getRandomValues()-backed rolls, AltFTool's standard Dice Roller uses that instead.
Up to 10. The minus and plus controls are clamped between 1 and 10 dice, and every die in a throw uses the type you selected — mixing a D20 and D6s in one roll isn't supported, so roll them separately.
Six standard polyhedral dice: D4, D6, D8, D10, D12 and D20. D4 and D6 render as pip faces with white dots; D8, D10, D12 and D20 display the rolled number in the middle of the die.
No — the tumble is a CSS animation, not a physics simulation. The result is decided the instant you press Roll, then the dice bounce and spin through random faces for 800 milliseconds before settling on it. The animation never changes the outcome.
It keeps the last 20 rolls, newest first, with die type, dice count, each individual face, the total and the time of the roll. That log lives in the page's memory only — reloading or leaving the page clears it, and nothing is written to your device or sent to a server.
Yes, free with no account and no usage limit. The whole tool is client-side JavaScript that runs in your browser, so there is nothing to install and no sign-in step before you roll.
Not in this roller — it tops out at D20 and simply sums the dice you threw, with no modifiers. AltFTool's standard Dice Roller covers d4 through d100 and supports modifiers and running statistics.
For an attack or skill check, select D20, leave the count at 1 and press Roll Dice. For an ability score, select D6 and set the count to 4 — you get all four faces listed individually plus their total, so you can drop the lowest yourself.
