## What is DiceOdds?

DiceOdds is a probability calculator for tabletop role-playing and board games. It does not roll dice for you — it tells you the exact odds before you roll, so you can plan the smart play.

Type any dice expression and instantly see the full distribution, the mean, the range, and the chance of hitting any target number.

EXACT MATH, NOT SIMULATION
Every result is computed exactly, not estimated from random samples. The numbers are the true probabilities.

BUILT FOR REAL TABLETOP ROLLS
- Standard notation like 3d6+2, 2d20, 1d8+1d6+3
- Advantage and disadvantage
- Keep and drop the highest or lowest dice (great for ability scores)
- Success pools: count how many dice beat a target number
- Expected damage per attack, including critical hits

SEE THE WHOLE PICTURE
A clear distribution chart shows how likely every outcome is, plus an "at least / at most" table for the chance to beat a difficulty class or armor.

QUICK COMMON ROLLS
One tap for the rolls you use most, and save your own expressions for next session.

PRIVATE AND OFFLINE
No sign-in, no ads, no tracking, no network access. Everything runs on your device.

One simple purchase. No subscriptions.
