Room for Chance

Random numbers

Generate integers within an inclusive range. Choose how many you need, allow or prevent repetitions and exclude specific values. Useful for exercises, informal selections and test data.

How it works

Generate integers within an inclusive range. Choose how many you need, allow or prevent repetitions and exclude specific values. Useful for exercises, informal selections and test data.

Each run is independent. These selections do not predict lottery results or certify a public prize draw.

Values and lists stay in this page. They are not sent to a server or saved after you close it.

Practical use cases

These are example results. A random selection can produce a different result each time.

Choose revision exercises

You have 35 exercises and have already completed numbers 1–5. Set the range to 1–35, request 3 numbers, enable no repetitions and exclude 1,2,3,4,5. This gives three different exercises still to practise. Keep the selected numbers if you want to follow the same plan later; generating again makes a new independent choice.

Example: 12, 24, 31: practise exercises 12, 24 and 31.

Pick one activity from six

Number six equally suitable activities from 1 to 6: reading, drawing, walking, cooking, music and a puzzle. Generate one number in that range and use it as the position in your list. Agree on the choices beforehand. If you need every activity once, use the list shuffler instead of repeatedly drawing one number.

Example: 4: choose cooking, the fourth activity.

Create small practice datasets

For an exercise about repeated values, set minimum 1, maximum 9 and quantity 6, then turn off the no-repetitions option. Repeated numbers are now valid, but are not guaranteed. Copy the result into your worksheet and count how often each value appears. This creates practice data, not observations from a real survey.

Example: 5, 2, 5, 9, 2, 1: values 2 and 5 each occur twice.

Random name picker

Paste a list and select one or more names at random. Each non-empty line is one entry; identical lines can be removed before selection. People with the same name can be distinguished with a label.

Random team generator

Divide a list into randomly assigned teams. Every person is assigned once and team sizes differ by at most one. Suitable for classroom exercises, workshops and friendly activities.

Shuffle a list

Randomise the order of names, topics or tasks while retaining every entry. Useful for presentation order and practice questions. Removing duplicate lines is optional.
