Random Number Generator 1 to 3
Three options and no good reason to prefer one? This random number generator 1 to 3 makes the call. One press gives you a 1, a 2, or a 3, each with an equal third of the chance. Map the numbers to your choices before you draw, and the argument is over.
History this session
How to pick one of three
- Write down what each number stands for, like three movies, three players, or three doors.
- Press Generate once for a single pick, and read the big number out loud.
- To rank all three options, switch to List of numbers, draw 3, and keep No repeats on. The list is a random order with no duplicates.
Three-way decisions made easy
The classic use is settling a choice between three things: which restaurant, which game, which teammate goes first. A random number 1 to 3 draw is also a stand-in for rock paper scissors when you want the computer to throw first: 1 is rock, 2 is paper, 3 is scissors.
In classrooms, a random number generator 1 to 3 picks between three groups or three activities without any claims of favoritism. Party hosts use it for three-person raffle draws, and families use it to choose between three weekend plans. Because the range is small, the result feels instant and final.
Three-option draws show up in unexpected places. Babysitters pick between three bedtime stories. Study groups pick between three practice exams. Improv teams draw one of three scene prompts before the timer starts. A number generator 1 to 3 keeps these moments quick, since the range is small enough to read at a glance and fair enough that nobody lobbies for a redraw. For a longer activity, draw in batch mode with repeats allowed and turn the results into a chart: after ninety draws, each number should sit near thirty. Kids can run the whole experiment themselves, which makes it a tidy introduction to expected value without any dice or spinners on the desk.
Small range, same fairness
A short range does not mean loose randomness. Every draw uses the browser's cryptographic random source, and the no repeats mode shuffles 1, 2, and 3 the way you would shuffle three cards. Over hundreds of draws, each number shows up about a third of the time. Teachers sometimes worry that a small range feels less random, yet the opposite holds for demonstrations: with only three outcomes, patterns and streaks show up fast, which is what makes the page handy for showing what chance looks like.
Frequently Asked Questions

Yes. One, two, and three each have a one in three chance on every single draw.
Can I use this random number generator 1 to 3 for rock paper scissors?
Yes. Assign rock to 1, paper to 2, and scissors to 3, then draw once per round.
