Random Number Generator
Yield a single random integer or generate an entire sorted list. Define your range and rules for a completely custom result.
Technical Capabilities
Generation Rules
Our generator uses high-entropy mathematical functions to ensure results are evenly distributed within your range.
- • Inclusive Range: Both your Min and Max values are included in the pool.
- • Large Sets: Effortlessly generate and sort lists of up to 10,000 numbers.
Unique vs. Dice
Choose Unique Numbers for draws like raffles or lottery simulations. Choose Allow Duplicates for simulations where each draw is independent, like flipping a coin or rolling multiple dice.

Frequently Asked Questions
How does a random number generator work?
Our tool uses a pseudo-random number generator (PRNG) algorithm built into Javascript. This is a computer algorithm that produces a sequence of numbers based on a cryptographic seed, approximating the mathematical properties of randomness.
Are the numbers generated by this tool truly random?
For most practical purposes like games, contests, or simulations, the numbers are sufficiently random. However, for high-security applications like cryptography, specialized hardware random number generators (TRNGs) are typically required.
What is the difference between 'Allow Duplicates' and 'Unique Numbers'?
When 'Allow Duplicates' is checked, the generator can produce the same number multiple times in a set, similar to rolling a die multiple times. When unchecked (Unique Numbers), every number in the set will be different, like a lottery ball draw.
