About Random Number Generator
This tool uses cryptographically secure random number generation via the Web Crypto API (crypto.getRandomValues) — the same method browsers use for encryption. Every number, coin flip, and dice roll is truly random, not pseudo-random like Math.random().
Common Use Cases

- Gaming: Simulate dice rolls for board games or RPGs.
- Decision Making: Flip a coin or pick a random option when you can't decide.

- Testing: Create random test data for software and databases.
