About DiceProbabilityCalculator.com

Who We Are

DiceProbabilityCalculator.com is a specialized tabletop gaming probability platform engineered and operated by Nisaj, a Canadian digital software studio based in Montreal, Quebec.

Too many dice tools on the web are buried under heavy lag, outdated flash applets, or clunky spreadsheets. We engineered this platform to run 100% in-browser using pure client-side mathematical combinatorics, delivering sub-millisecond calculation speed and interactive SVG probability distributions with zero server delays.

Our Mathematical Standards

Every probability curve and combat simulation on this platform is derived from exact discrete probability mass functions:

• Polynomial Convolution: Exact multi-dice sums (such as 3d6 or 8d6 Fireball) are computed using exact algebraic polynomial expansion rather than Monte Carlo approximations.
• D&D 5e Ruleset: Advantage and Disadvantage curves follow the exact order statistics of rolling two independent uniform discrete random variables on [1, 20].
• Warhammer 40k 10th Edition: Combat pipelines accurately model sequential dependencies between Ballistic/Weapon Skill, Strength vs Toughness comparison tables, Armor Penetration modifiers, and Feel No Pain rolls.
