D12 Roller
The d12 is the most underrated die in the bag. Roll this twelve-sided dodecahedron in realistic 3D and watch it roll smoothly across the table before it settles on a number from 1 to 12.
In D&D it rolls greataxe damage and is the barbarian hit die. Need 2d12 + 5? Add another d12 or a modifier in Dice → Polyhedral, and 3DRoll shows each die along with the total.
How to roll
- Tap the ROLL button, tap any die, or swipe across the table to throw.
- Press and hold the button or a die to charge up — the longer you hold, the wilder the dice bounce and the higher they fly.
- On a phone, simply shake it to roll.
- Double-tap a die to lock it so it stays put on the next roll.

FAQ
How do I roll a d12 with a bonus?
Open Dice → Polyhedral, tap d12 and set the modifier to your bonus. The total is calculated for you.
Are the numbers easy to read?
Yes. Each face shows a large number from 1 to 12, and the 6 and 9 are underlined so you never confuse them.
Is 3DRoll free?
Yes. 3DRoll is completely free, with no sign-up and nothing to install. Just open the page and roll.
Are the rolls really random?
Each throw starts with a random spin and force, then a physics engine simulates the dice bouncing and settling. The face that ends up on top is the result, just like real dice.
