What is a Random Number Generator?
A random number generator (RNG) is a tool that produces numbers or selections that have no predictable pattern. Our generator uses JavaScript's built-in Math.random() function to create pseudo-random results suitable for everyday use cases.
This tool offers two modes: Random Numbers for generating numbers within a range, and Random Picker for selecting items from a custom list.
Random Number Mode
Generate one or more random integers between a minimum and maximum value. Perfect for dice rolls, lottery numbers, random sampling, or any situation where you need random numbers.
Random Picker Mode
Enter a list of items separated by commas, and the generator will randomly select one or more items. Great for making decisions, choosing winners, or randomizing selections.
Common Use Cases
- Games & Gaming: Dice rolls, card draws, random encounters
- Raffles & Giveaways: Select random winners from a list of participants
- Decision Making: Can't decide? Let randomness choose for you
- Education: Generate random quiz questions or student order
- Statistics: Create random samples for surveys or research
- Team Selection: Randomly assign people to groups or teams
Duplicates Option
The "Allow Duplicates" checkbox controls whether the same number or item can appear multiple times in your results. When disabled, each result will be unique - useful for lottery-style selections or when you need distinct items.
