How to use the Random Number Generator
Single or multiple numbers
Generate one random number within any range you set. Enable "Multiple numbers" mode to generate a list — useful for lottery picks, raffle draws or random sampling. The "No repeats" option ensures each number only appears once.
Dice roller
Click any dice type (D4 through D100) for a quick roll. Adjust the number of dice to roll multiple at once — total shown below. Enter a custom number of sides for any non-standard dice. Previous results build up as chips on screen.
True randomness can't be produced by software alone — only pseudo-random sequences. Modern operating systems mix in 'entropy' from mouse movement, keyboard timings, and hardware noise. The Linux /dev/random pool draws on ~13 different entropy sources.
