Random Number Generator
This random number generator returns one or more numbers picked at random within the range you choose. Set a minimum and a maximum, decide how many numbers you want, and the tool instantly draws values with equal probability across the range. It is handy for raffles and prize draws, board and party games, picking a winner, choosing a random sample, or simply making a decision when you cannot make up your mind.
Result
Numbers are generated at random in your browser and change every time you press "Generate". If you request more than one, values may repeat.

How it works
You give the generator a lower bound (minimum) and an upper bound (maximum), and it produces whole numbers anywhere between them, both ends included. Each draw uses your device's built-in randomness, so every value in the range has the same chance of coming up and results are independent from one press to the next. When you ask for several numbers at once, each one is drawn separately, which means the same value can appear more than once. If you happen to enter a maximum that is smaller than the minimum, the generator simply swaps them so the range still makes sense. It helps to tell two ideas apart: a pseudo-random number is computed by a browser algorithm from an internal seed — unpredictable in practice and perfect for raffles, games, sampling or assigning turns — while a truly random number comes from a physical source such as thermal noise or radioactive decay and is only needed for cryptography or lotteries with legal standing. To pick a winner from a list, number each person and draw a value between 1 and the total; to build a quick password or a PIN, generate several digits and combine them.
How to set up the generator for each use
The same generator handles very different tasks: you only change the minimum, the maximum and how many numbers you want. These are the most common settings:
| Typical use | How to set it up |
|---|---|
| Roll a die (1–6) | Minimum 1, Maximum 6, count 1 |
| Flip a coin | Minimum 1, Maximum 2 (1 = heads, 2 = tails) |
| Draw among N participants | Minimum 1, Maximum N, count 1 |
| Raffle ticket from 1 to 1000 | Minimum 1, Maximum 1000, count 1 |
| Lottery like 6 from 49 | Minimum 1, Maximum 49, count 6 |
| 4-digit PIN | Minimum 1000, Maximum 9999, count 1 |
| Split people into N teams | Minimum 1, Maximum N, count = number of people |
| Random percentage | Minimum 0, Maximum 100, count 1 |

Preguntas frecuentes
- How do I generate a random number in a range?
- Enter the smallest value you want in the Minimum field and the largest in the Maximum field, leave "How many" at 1, and press Generate. The tool returns a single whole number somewhere between the two limits, both included.
- Can I generate more than one number at once?
- Yes. Set "How many to generate" to any value up to 100 and press Generate. Each number is drawn independently, so the results are shown together as a list and the same value can appear more than once.
- Are the numbers truly random?
- They use the pseudo-random generator built into your browser, which is more than enough for raffles, games, and everyday choices. It is not intended for cryptography, lotteries with legal weight, or security keys.
- What happens if the maximum is smaller than the minimum?
- The generator automatically swaps the two values, so if you type a maximum below the minimum it still produces numbers within the correct range instead of failing.
- Can the same number come up twice?
- Yes. Because each draw is independent, when you generate several numbers repeats are possible — just like rolling the same dice number twice. If you need unique values, generate a few extra and discard the duplicates.
- Is it good enough for a fair draw?
- Yes. Every number in the range has exactly the same probability of coming up, so numbering the participants from 1 to the total and drawing a value gives you an impartial winner. For draws with valuable prizes or legal requirements you should use a certified system and keep a record of the process, but for a raffle among friends, in class or on social media it is more than enough.
