About This Random Number Generator
This tool uses your browser's built-in cryptographically seeded pseudo-random number generator to produce unpredictable results. While it is not suitable for cryptographic security applications, it is perfectly appropriate for games, competitions, classroom activities, decision-making, and statistical sampling.
Common Uses
Random number generators are used in a surprisingly wide range of everyday situations. Teachers use them to randomly select students for questions or group assignments. Event organisers use them to pick raffle winners fairly. Developers use them to generate test data. Statisticians use them to create random samples from a population. Gamers use them to simulate dice rolls or card draws.
Unique vs Repeated Numbers
When generating multiple numbers, you can choose whether to allow repeats. Unique mode (no repeats) is equivalent to drawing numbered balls from a bag without replacement — like a lottery draw. Repeated mode allows the same number to appear more than once, equivalent to rolling a die multiple times.
Picking from a List
The list picker is ideal for choosing raffle winners, randomly assigning tasks, or picking a name from a group. Simply enter one item per line and specify how many to pick. The selection is always made without replacement, so no item can be chosen twice in the same draw.
