What this tool is built for
Generate random numbers within a range. Set quantity, decimal precision, step and exclusions, or choose numbers without repeats.
The available controls include: Min · Max · Quantity; Decimal places · Step · Exclusions; Unique · Order; History · Download CSV.
For a quick result, you can use the tool directly on this page. If you need to run an activity with other people, create an account and use the dashboard to create and manage a shared room.
How to use it
Set up only the options you need, run the tool, then review the result and history before starting another round.
Set the minimum and maximum values for the range.
Choose one number or generate a batch of values at once.
Enable unique mode when every generated number must appear only once.
What you can do
The page combines the core tool with controls that are specific to this task rather than a generic randomizer interface.
- Min · Max · Quantity
- Decimal places · Step · Exclusions
- Unique · Order
- History · Download CSV
- Shared rooms with participants, invitation links and access settings
Where it works well
The best setup depends on whether you need a single local result or a shared activity that other people can follow.
Tickets: choose five different numbers from 1 to 100.
Practice data: use a step of 0.5 and one decimal place between 0 and 10.
Everyday decisions: reduce small choices to a clear list and let the tool choose from the options you entered.
Classroom: choose pupils, create exercises, split groups or make turn-taking visible to everyone.
Test data: generate sample values inside a controlled range for demos, exercises and non-sensitive testing.
Giveaways: draw from a prepared list and keep the selection process easy to follow.
How the result is produced
The range, step and exclusions define the available values. Without repeats, the requested quantity cannot exceed that pool.
Shared rooms add a controlled group workflow: the organizer can choose access rules, add participants or let them enter themselves, share a room link, and invite people by email. What participants can see or control depends on the room settings and their role.
Capabilities and limits
Use the tool for games, lessons, workshops and everyday organization. It is not intended to replace certified draws, regulated records, medical timing or other contexts that require an audited or authoritative system.
Practical tips
- Name entries clearly before starting so participants can understand the result without extra explanation.
- Check the important settings before sharing a room; viewers may not have the same controls as the organizer.
- Use history or exported results when the tool provides them instead of relying on screenshots alone.
