About this roller
DnD Dice Roller (dnddiceroller.org) rolls every die with your browser's cryptographically secure random number generator, crypto.getRandomValues, and uses rejection sampling so every face is exactly equally likely. The 3D dice only animate a result that has already been decided this way; the physics never picks the number. Rolls happen on your device and are never sent to our server.
