How it works:

This tool generates random numbers using PHP's Mersenne Twister algorithm (mt_rand), which is a fast pseudo-random number generator suitable for general purposes like games, simulations, and random selections. While not cryptographically secure, it provides good statistical randomness for everyday use cases.

For unique number generation, the tool creates an array of all possible numbers in your range, shuffles it randomly, and then selects the requested count. This ensures true uniqueness without repetition.
