Roll real 3D dice in your browser.
Pick your dice, throw them into the tray and read the result off the faces that land up. No number is chosen for you: the tumble decides, the way it does at the table.
How the roll works
Every die is a real solid: a tetrahedron, a cube, an octahedron, a pentagonal trapezohedron, a dodecahedron and an icosahedron. When you roll, each one is thrown into the tray with a random speed, spin and orientation, and a rigid-body physics engine bounces it off the felt, the rim and the other dice until it stops.
Only then is the result read: the face whose normal points straight up is the number you rolled, and on the d4 it is the corner that points up. A die that ends up leaning on the rim or on another die is flicked and lands again, the way you would nudge a cocked die.
That makes the roll as fair as the physics is chaotic: two throws never start alike, and nothing about the outcome is known before the dice stop. With advantage or disadvantage every d20 is thrown twice and the dropped die stays in the tray, faded.
Questions
Is the roll random, or is the number picked first?
Nothing is picked first. Each die gets a random position, speed and spin, the physics runs, and the value is read off the face that lands up. That is how D&D Beyond rolls too.
Which dice can I roll?
The full D&D set: d4, d6, d8, d10, d12 and d20, up to 24 dice in one roll, with a modifier and advantage or disadvantage for the d20s.
Does it work on a phone?
Yes. The tray uses WebGL, which every current phone browser has. If 3D cannot start, the page still rolls with a plain random number so you are never stuck.
Can I use these dice on the virtual tabletop?
The tabletop is about the map: build a 3D battle map and run the fight on it. This roller is a free stand-alone tool; keep it open in a tab next to the table.
