This article demonstrates how to reverse common pseudo-random number generators (such as linear congruential generators, XOR shift, and Flash's RNG), and shows a practical attack by predicting mine positions in a Minesweeper game, emphasizing that ordinary random numbers should not be used in security contexts.

An exploration of pseudo-random number generation in computers, focusing on linear congruential generators (LCGs) and their quality visualization. The article also touches on entropy sources like Cloudflare's lava lamps and serves as a precursor to property-based testing.
