Random Number Generator
Generate random numbers within any range instantly.
Frequently Asked Questions
Are the numbers truly random?
The generator uses a cryptographically seeded random function for high-quality, unpredictable results.
What range can I use?
Any integer range is supported, including negative numbers. For example, -100 to 100 is perfectly valid.
Can I generate numbers with decimal places?
This tool generates whole integers. For decimal numbers, use the Percentage Calculator or perform the scaling manually.
Can the same number come up twice in a row?
Yes. Each generation is independent, so the same number can theoretically appear multiple times in succession.
Can I use this to simulate a dice roll?
Yes. Set Min to 1 and Max to 6 for a standard die. Set Max to 20 for a D20, or any other value for custom dice.
Random Number Generator — Instant Numbers Within Any Range
Random numbers are fundamental to everything from video games and probability experiments to cryptography and statistical sampling. Our Random Number Generator lets you produce a random integer within any range you define — 1 to 6 for a custom die roll, 1 to 100 for a percentage draw, 1 to 1000 for a raffle, or any range you need, including negative numbers.
The generator uses a high-quality pseudo-random algorithm seeded from system entropy at the time of the click. This makes it suitable for games, competitions, draws, and educational purposes where a fair, unpredictable outcome matters.
Practical uses include: rolling a custom-sided die for tabletop games, drawing a raffle number from a pool of entries, randomly selecting a page number from a book, generating a random seed for a procedural game, picking a random index from a list, assigning random values in probability experiments, and making any number-based random selection.
