Dice probability

Compute the exact odds for NdS dice rolls — at least, at most, exactly, or a range — with the full distribution.

Computed exactly in this browser — dynamic programming over every outcome, not a simulation.

Uniform fair dice. The distribution lists every reachable total with its exact count of outcomes.

How to use

  1. Set the number of dice and sides.
  2. Pick the condition and target.
  3. Read the probability and the distribution table.

What it supports

Exact integer distribution via dynamic programming — no simulation error. Up to 50 dice and 1,000 sides with a work cap of count×sides ≤ 20,000. Results assume fair, independent dice.
