How Our D12 Roller Works

We use JavaScript’s built-in Math.random() function—seeded on page load—to generate integers from 1 to 12, each with equal probability. This ensures every roll mimics the unpredictability of a physical 12-sider.

How to Roll Your D12

  1. Set your quantity: Enter how many D12s you need.
  2. Hit “Roll”: Click the button and watch the results populate.
  3. View outcomes: Each individual roll displays instantly.

Pro tip: Remember, the average roll on a D12 is 6.5—perfect for pacing your damage expectations. Pair this roller with our “Advantage” feature by rolling twice and taking the higher result when your character has a buff!
