Need a fair random number for your game night? Here's how to use random number generators for D&D, board games, and tabletop RPGs — with presets for every situation.

The Problem: Physical Dice Aren't Truly Random

A study by the University of Dundee found that cheap dice have a statistical bias of up to 20% toward certain numbers due to manufacturing imperfections. Digital RNGs use cryptographic algorithms for true randomness.

Frequently Asked Questions

How do I generate random numbers for D&D?

Use our random number generator with presets: d4, d6, d8, d10, d12, d20, d100. Set min to 1, max to the die size, and click generate. For multiple dice, generate multiple times or use the bulk option.

Is a digital random number generator fairer than dice?

Yes. Digital RNGs use the Web Crypto API which produces cryptographically secure random numbers. Physical dice have manufacturing biases — some numbers roll 5-20% more often than others.

Can I use this for lottery numbers?

You can generate random lottery numbers, but remember: lottery odds are the same whether you pick numbers randomly or use 'lucky' numbers. The randomness of the draw matters, not your number selection.
