Frequently Asked Questions
Prizm Quest Roller is a free 3D dice rolling web app for tabletop RPGs. It rolls the full polyhedral 7 set — d4, d6, d8, d10, d12, d20, and d100 — with realistic physics, modifiers, advantage, dice pools, and saveable spell buttons for D&D and Pathfinder.
Each die is a real 3D mesh simulated with cannon-es physics and rendered by three.js in a WebGL canvas. Random spin, lift, and settle forces tumble the die inside a tray, and the resting face is read off the mesh so every roll is fair, visible, and mechanically correct.
Any tabletop system using standard polyhedral dice works out of the box, including Dungeons & Dragons 5e, Pathfinder 1e and 2e, Call of Cthulhu, Shadowrun d6 pools, World of Darkness, Blades in the Dark, and most OSR games. Custom spell buttons let you save Fireball 8d6, sneak attack, or any pool.
