About Random Number Generator
A random number generator produces unpredictable numbers using cryptographically secure algorithms (crypto.getRandomValues). Unlike Math.random(), this provides true randomness suitable for games, lotteries, and fair selections. It supports three modes: range (min-max), dice rolling, and lottery number drawing.
How to Use
Select a mode: Range to generate a number between min and max, Dice to roll 1-10 dice, or Lottery to pick unique numbers from a pool. Click the generate button to create random numbers. Results are saved in a history list. Copy any result with one click.
Common Use Cases
- •Drawing lottery or raffle numbers for events
- •Rolling dice for board games and tabletop RPGs
- •Randomly selecting winners from a list of participants
- •Generating random test data for software development
