Random Number Generator
Pick a random number between any two values — or draw up to 100 at once, with or without repeats. Free, instant and no account needed.

What a random number generator is actually for
A random number generator answers one deceptively simple question: give me a number in this range, and give me no reason to argue with it. That neutrality is the whole point. The moment a person picks the number themselves, someone in the room can claim the choice was steered — and in a classroom, a raffle or a team meeting, that suspicion costs more time than the decision itself.
Teachers use it to choose which seat number recites next, which page of the workbook the class starts on, or which of forty students demonstrates a problem on the board. Because the number comes from the screen rather than from the teacher, nobody reads it as favouritism. The same logic makes it useful for assigning presentation order, picking group leaders, or deciding which row packs up first at the end of the day.
Business and office uses
Offices reach for random numbers more often than they realise. Quality teams sample invoices for audit by drawing record numbers at random, which is a defensible sampling method precisely because it removes human choice. Support teams assign an unpredictable ticket for a spot check. Recruiters shuffle interview order so that nobody benefits from always going last. HR draws numbered tickets for a company giveaway in front of everyone rather than behind a closed door.
Games, teaching statistics, and everyday decisions
Board game players use it when the dice have gone missing, and dungeon masters use it for damage rolls beyond standard dice. Statistics teachers use a live generator to demonstrate the law of large numbers: draw ten numbers between 1 and 6 and the distribution looks lumpy; draw a hundred and it flattens out, which is a far more convincing lesson than a textbook paragraph. Developers use it to produce quick test data, and writers use it to pick a random page or prompt.
How to get the most out of this tool
Set your minimum and maximum first — both endpoints are included, so 1 to 100 really can return 1 or 100. If you are drawing several winners and the same person should not win twice, turn on No repeats; the tool will tell you if you have asked for more unique numbers than the range contains. Use the copy button to paste results straight into a chat thread or a spreadsheet, so there is a record of what was drawn and when.
If what you actually need is a name rather than a number, the spin the wheel picker shows the draw happening on screen, which audiences find far more convincing than a number appearing in a box. For splitting a class or a sports squad, the team generator distributes people evenly in one step, and for a straight two-way call the coin flip is faster than typing a range.
Random Number Generator FAQ
How does this random number generator work?
Each number is drawn using crypto.getRandomValues(), the browser’s cryptographically secure random source, with rejection sampling to remove modulo bias. That means every number in your range is equally likely, unlike simple Math.random() implementations that can skew slightly at the edges of a range.
Can I generate more than one number at a time?
Yes. Set the "How many" field to any value from 1 to 100 and every number is drawn in a single click. Tick "No repeats" if you need a unique set, for example when drawing ten different raffle ticket numbers out of a thousand.
Can I use negative numbers or zero?
You can. The minimum and maximum accept negative values and zero, so a range of -50 to 50 works exactly as you would expect. The generator includes both endpoints, so a range of 1 to 6 can return 1 and 6.
Is this suitable for a prize draw or raffle?
It is well suited to informal raffles, classroom draws and giveaways. For regulated gambling or legally binding lotteries you should use a certified randomness provider, because those contexts require audited hardware and documented procedures that no free website can supply.
Do you store the numbers I generate?
No. Generation happens entirely inside your browser and nothing is transmitted to our servers. The last ten results are held in memory for your convenience and disappear as soon as you close or refresh the tab.
