Random Number Generation

Natural 20 Lite utilizes your device's built-in randomizer (arc4random_uniform) to generate values. Extensive testing has been conducted to ensure the absence of bias, even with large numbers of dice. Natural 20's full version includes a "Distribution" screen, which allows you to personally test this randomness by rolling 100,000 dice at a time.
