Random Number & Name Picker — Fair Random Draw with Animation
Draw random numbers from a custom range or pick random winners from a name list. Optional no-duplicate mode and roulette animation for fair, transparent draws.
Frequently Asked Questions
Q. Is the draw truly random?
Yes. The tool uses Web Crypto API (`crypto.getRandomValues()`) for cryptographically secure, unpredictable randomness — far superior to `Math.random()`.
Q. What does "No duplicates" mean?
In no-duplicate mode, each number or name can only be drawn once. Example: drawing 5 from 1–10 gives 5 distinct numbers with no repeats.
Q. How many names can I enter?
There is no hard limit. Enter as many names as needed, one per line. Just ensure the draw count does not exceed the total names when using no-duplicate mode.
Q. Can I use this for lottery numbers?
Yes! Set range 1–45, draw 6 with no duplicates — that's the same method as most lotteries. Note: this does not guarantee winning numbers.
Q. Is the result saved?
Yes, the last 5 draws are stored in your browser session. You can also click "Copy" to copy results to your clipboard for sharing.
Q. Is the roulette animation manipulated?
No. The final result is determined the moment you click "Draw!" The animation is purely visual — the outcome is fixed before the spinning begins.
How to Use
Choose "Random Number" or "Name Draw" tab.
Set number range or paste names (one per line), then choose how many to draw.
Click "Draw!" — a roulette animation plays before revealing the result.

Expert Knowledge: Random Number & Name Picker — Fair Random Draw with Animation
The fairness of a random draw depends entirely on the underlying random number generator. Standard `Math.random()` uses a Linear Congruential Generator (LCG) — predictable if the seed is known. The Web Crypto API uses the OS hardware entropy source (mouse movements, key timing, etc.) to provide true, cryptographically secure randomness (CSPRNG). Any official raffle, giveaway, or game requiring verifiable fairness should use a CSPRNG rather than a simple `Math.random()` call.
