Question 1

What dice does this roller support?

Accepted Answer

D4, D6, D8, D10, D12, D20, D100 (percentile) and custom N-sided dice. You can roll multiple dice at once (e.g. 3d6+2) and add a modifier bonus.

Question 2

Does the roller support D&D advantage and disadvantage?

Accepted Answer

Yes. Pick any dice type, choose D&D Advantage or Disadvantage mode, and the tool will roll twice and keep the higher or lower result.

Question 3

Is the dice roller truly random?

Accepted Answer

It uses the browser built-in crypto.getRandomValues() function when available (a cryptographically secure source), falling back to Math.random() otherwise. Each roll is independent and unbiased.

Question 4

Can I see my roll history?

Accepted Answer

Yes. The last 50 rolls are shown below the dice, with the formula, individual values, modifier and total. You can clear history at any time.
