About Dice Parlor
A handful of free helpers for game night: the odds behind dice and cards, and a few tools to keep the table running.
What it does
The dice probability calculator and the dice pool calculator show the exact chance of every result. Card draw odds answers “will I draw it in time?”. The initiative tracker, point buy calculator and turn timer handle the bookkeeping, so the evening goes on the game.
Exact, not simulated
Every probability on the site is calculated, not estimated by rolling virtual dice thousands of times: dice by convolution and counting, cards with the hypergeometric distribution. Each tool page explains its method in plain words and names its sources, so you can check the numbers yourself.
It all happens in your browser
The tools run on your own device. Nothing you type is sent anywhere; the initiative tracker and your colour theme are kept in your browser's local storage. The site counts page views with Cloudflare Web Analytics, which uses no cookies and never receives what you type into the tools. The privacy page has the details.
Games, names and rules
Dice Parlor is not connected with any game publisher, and its examples are deliberately generic. The point buy calculator follows the 5th edition System Reference Document, used under the Creative Commons Attribution 4.0 licence; its page carries the full attribution.
The site has no accounts, no adverts and nothing to buy.
