How it works
The formula behind this calculator.
result = min + rand × (max − min + 1); crypto where available
- min, max
- Inclusive bounds
- count
- How many numbers to draw
Pseudo-random numbers are fine for games and prototyping. For cryptography, lotteries, or anything needing unpredictability, use a CSPRNG.
Example: min=1, max=6, count=1 simulates a 6-sided die roll
Ref: Mersenne Twister (most JS engines); xoshiro256** in modern environments
Tips
- 💡 Need a fair 6-sided die? Use min=1, max=6, count=1.
- 💡 For lotteries, change the default range and count.
