Frequently Asked Questions
- Is this truly random?
- Yes! This generator uses the Web Crypto API (crypto.getRandomValues()) which provides cryptographically secure random numbers. This is much better than basic JavaScript Math.random() and suitable for security-sensitive applications.
- Can I generate multiple numbers at once?
- Absolutely! Set "How many numbers?" to any value up to 1000. You can also enable "Unique numbers" to ensure no duplicates appear in your results.
- What's the maximum range I can use?
- You can use any integer range. Common uses include 1-10, 1-100, or even 1-1000000. The generator handles both positive and negative numbers.
- What's the difference between unique and non-unique?
- Unique means each number appears only once (like drawing lottery balls). Non-unique allows the same number to appear multiple times (like rolling dice multiple times).
- Can I use this for lottery numbers?
- Yes! Set your range (e.g., 1-49), quantity (e.g., 6 numbers), and enable "Unique numbers" and "Sort results" for lottery-style number generation.
- How do I use presets?
- Click any preset button to instantly set common ranges. "1-6 (Dice)" simulates rolling a die, "0-1 (Coin)" simulates a coin flip (0=heads, 1=tails), etc.
