Random Number Generator

This online random number generator is a simple little helper for all the moments when you need a fair pick and don’t want to argue about it. Use it as a random number picker for homework, a quick RNG tool for games, a coin flip alternative, a dice roller, or even a basic lottery number generator when you are testing strategies. Set the range, choose how many numbers you want, hit Generate, and the tool will do the work for you.

How to use this RNG tool

Set the minimum value – In the “Minimum value (inclusive)” field, enter the smallest integer that should be allowed in your results. For example, 1.
Set the maximum value – In the “Maximum value (inclusive)” field, enter the largest integer that can appear. For example, 100.
Choose how many numbers to generate – Type how many random integers you want. You can generate just one number or a whole list.
Decide if repeats are allowed – If “Allow repeated numbers” is checked, the same number can appear more than once. If you uncheck it, the tool behaves like a number picker that draws unique values from the range.
Pick the order of the result – Use “Order of the result” to keep numbers as they were drawn, or sort them in ascending or descending order. This is handy when you want organized output for notes, spreadsheets, or forms.
Use quick presets – The preset buttons fill in common ranges for you, such as a coin flip (1 to 2), a standard dice roll (1 to 6), or 1 to 10 for quick random picks.
Press “Generate” – The tool will briefly animate while it draws the result, then show your final numbers in a large block so you can see them right away.
Copy or clear the result – Use “Copy result” to quickly put the output into chats, docs, or spreadsheets, and “Clear results” if you want to reset everything to the default 1 to 10 range.

How this random number generator works

Under the hood, this tool is a random integer generator built for everyday use. When you click Generate, it creates numbers inside the exact range you specified, including both the minimum and maximum values.

The generator uses randomness from your browser. If your device supports cryptographic randomness through the browser (for example, via secure random functions), the tool taps into that source first. This kind of randomness is better for distribution than basic math based randomness, since it is harder to predict from the outside.

In addition to that cryptographic source, the tool mixes in extra randomness based on internal math and timing. This combined approach helps spread values more evenly across your chosen range over many runs. The result is an RNG that behaves well as a general purpose randomizer, random number picker, dice roller, or coin flip simulator.

If you disable repeats, the tool switches to a “draw without replacement” mode. In that case it keeps track of already used numbers and keeps drawing fresh values until it reaches the requested count or runs out of possibilities. If you ask for more unique numbers than the range can provide, the tool warns you and asks you to adjust your settings.

Once the raw random integers are generated, the tool optionally sorts them according to your chosen order. The sorting step does not change which numbers were drawn, it only rearranges them so that you can read or copy the list more easily. After that, the numbers are rendered in the main result area and also saved in the “Recent generations” list so you can glance back at your last few draws.

FAQ

Is this random number generator truly random?

For normal use cases like picking a random number, simulating dice rolls, or doing quick random draws for games, this tool is “random enough.” It uses cryptographic randomness from your browser when available and mixes in extra internal variation. That said, no simple online RNG should be treated as a certified source for high risk applications like real money casino systems or national lotteries.

Can I use this tool to pick lottery numbers or gambling results?

You can use it to practice or simulate lottery picks, generate ideas, or test strategies, but you should not rely on it as an official gambling system. Real world lotteries and casinos use their own random systems. Treat this as a free, convenient randomizer and number picker for personal use only.

How many random numbers can I generate at once?

The tool lets you generate up to a large batch of numbers in a single click within the range you choose. If you ask for more unique numbers than your range can support, you will see a clear error message. This keeps the random number generator fast, stable, and easy to understand even when you request a long list.

Are my generated numbers stored anywhere?

The results are displayed in your browser and kept in the “Recent generations” list so you can see what you just did. That history lives only in your current session in the browser. There is no login, no account, and no link between you and a specific sequence of numbers on this page.

What else can I use this randomizer for besides plain numbers?

Many people use a random number generator as a flexible “random picker” in disguise. You can map numbers to items in a list, students in a class, questions in a quiz, tasks on a to do list, or seats in a room. Assign each item a number, use the RNG to pick one or many results, and then match the numbers back to your real world list.
