How to use Random number generator.

01

Set the range

Choose the minimum and maximum values, then decide whether the result should use integers or decimals.

02

Choose the quantity

Generate one value, a unique set, or allow repeats when the same number may be drawn more than once.

03

Select the method

Use secure browser randomness for ordinary draws, a seed for repeatable results, or the wheel for a visible sequence.

04

Keep the record

Copy the numbers and review the settings, time and result details when the draw needs to be explained.

Ways to use Random number generator.

Games and raffles

Draw values from a defined range without preparing slips of paper or a physical spinner.

Classroom examples

Create sample values for arithmetic, probability, data and estimation exercises.

Testing data

Generate bounded numbers quickly when a prototype, worksheet or demonstration needs sample inputs.

Repeatable exercises

Use a seed when everyone should be able to reproduce the same sequence from the same settings.

Before you use the result.

Use no-repeats only when the requested quantity fits inside the selected integer range. A seeded draw is repeatable and useful for demonstrations, while the default secure random mode is better when the outcome should not be predictable in advance.

Continue with the next fair draw.
