The article reverses engineers Factorio's pseudo-random number generator to enable deterministic control over quality roll mechanics introduced in the Space-Age DLC. It explains how the PRNG works under the hood and how players can use this knowledge to reliably craft high-quality items instead of relying purely on statistical probability.
Background
Factorio is a popular factory-building simulation game known for its deterministic mechanics. The Space-Age DLC introduced item quality systems that rely on RNG rolls, prompting players and modders to reverse-engineer the underlying random number generator.
