What people use a random number 1 to 100 for
Teachers are the biggest group of users. Number the students in a class, and a draw picks who answers next, who presents first, or who leads the line. Because a random number generator 1 to 100 treats every value the same, nobody can argue the pick was rigged. The same trick works for reading groups, quiz teams, and handing out numbered prizes at a school fair.
At home, the tool settles board game disputes, replaces a missing die when you set the range smaller, and draws raffle winners at parties and charity events. If you play tabletop games, two draws from 1 to 100 stand in for percentile dice: the first number is the tens digit, the second is the units.
Students use it for probability practice too. Draw thirty numbers, chart how often each decade appears, and you have a hands-on lesson about uniform distributions that beats any worksheet.
Fair randomness, and nothing leaves your browser
The numbers come from crypto.getRandomValues, the browser's cryptographic random source, not the older Math.random function. A rejection step removes the small bias that a plain modulo would add, so every value in your range has the same chance. The page makes no network calls when you generate, stores nothing on a server, and the history list vanishes when you close the tab. You can load the page once and keep using it with your connection off.
Want to check the spread yourself? Draw a batch of one hundred with repeats allowed and tally how often each decade appears. The bars never match perfectly, yet they stay close, which is what fair randomness looks like in practice. Refresh and repeat, and the shape holds. Every value in the range has the same chance on every draw, whether the last draw was a 1 or a 100.
