Free random number generator. Pick random whole numbers in any range, with or without repeats. Roll a dice, draw winners or choose a sample fairly.
Enter your values and select Calculate to see the result.
Random numbers are used to pick a winner, roll a dice, choose a sample, assign teams or settle a decision fairly. Doing it by hand tends to favour numbers that feel random rather than numbers that truly are.
Enter a minimum and a maximum, how many numbers you want and whether repeats are allowed. The generator uses your browser's cryptographic random number generator, so every value in the range is equally likely. Results are produced on your device and are not stored.
each number is drawn uniformly at random from min to max using a cryptographic random generator
Choose 1 to 6 and one number to simulate a dice roll, or 1 to 49 with six unique numbers for a lottery-style draw.
They come from your browser's cryptographic random number generator, and each value in the range is equally likely. The method avoids modulo bias, which can skew simple random number code.
For a six-sided dice, set the minimum to 1 and the maximum to 6. For a coin flip, use 1 to 2 and treat one as heads and two as tails.
Set the amount you need and choose that every number is unique. The generator never repeats a value and checks that the range is large enough.
It is fine for games, raffles and sampling. For passwords use the password generator, and use official draw procedures for regulated lotteries.
