Random Number Generator
Generate random numbers within any range
What is a Random Number Generator?
A random number generator picks one or more integers within a minimum and maximum range you define — ideal for raffles, classroom picks, board games, simulations, and fair decision-making when you need unbiased integers.
Optionally generate unique numbers with no repeats, which is useful for drawing winners without duplication. The tool runs in your browser with no account required and works offline once the page is loaded at no cost.
How to Use This Random Number Generator
- Enter minimum and maximum values (inclusive).
- Set count — how many numbers to draw (up to the limit shown).
- Enable unique numbers if duplicates are not allowed.
- Click Generate to see results; click again for a new draw.
- Copy or screenshot results if you need a record for a game or classroom audit trail.
Notes
Randomness uses secure browser APIs when available, with fallback for compatibility. For legally regulated lotteries or gambling, use official certified systems — this tool is for casual and educational use.
When unique mode is on, the maximum count equals the number of integers in your range inclusive. For large ranges and small counts, each draw remains fair without replacement across the whole batch.
Frequently Asked Questions
Can I pick multiple random numbers at once?
Yes. Set count to the number of values you need. Each generated integer falls within your min–max range unless unique mode limits how many you can draw.
What does “unique numbers” mean?
When enabled, no duplicate values appear in a single batch. You cannot request more unique numbers than exist in the range (max − min + 1).
Is every outcome equally likely?
Yes, within the inclusive range, each integer has equal probability for each draw when duplicates are allowed. Unique mode samples without replacement.
Can I generate decimals?
This tool generates integers only. For decimal ranges, scale inputs (e.g., treat 1–1000 as thousandths) or use a dedicated decimal random tool if we add one later.
What range should I use for a 1–100 dice roll?
Set minimum to 1 and maximum to 100 for a percentile-style draw, or 1–6 for a standard die. Set count to 1 and click Generate each time you roll. For visual random choices with labels, try our Decision Maker.
