3D Dice Roller

This dice roller covers the full polyhedral set — d4, d6, d8, d10, d12, d20 and d100 — so it works for Dungeons & Dragons, Pathfinder, board games and any time a physical die has gone missing under the sofa. You can throw up to 20 dice at once, add a modifier from −20 to +20, and read the running total, the per-die breakdown and a "Natural 20" or "Natural 1" banner on a d20.

Fairness matters when a roll decides the game, so the results are not a plain Math.random() call. The tool draws from the browser's cryptographic generator (crypto.getRandomValues) and uses rejection sampling to strip out the tiny bias that modulo maths would otherwise introduce — every face has an equal chance. The tumbling animation is just for feel; the number underneath is a true uniform roll.

For tabletop players there is D&D 5e advantage and disadvantage on the d20: it secretly rolls two dice and keeps the higher or lower one, showing you both. A one-tap coin flip, saved presets like 2d6 and 3d8+2, all-time stats (rolls, best total and natural-20 count) and a history of your last 30 rolls round it out.
