What is a maze seed?
A seed is a whole number that pins down every random choice a maze makes. Same recipe, same seed — the same maze, exactly, every time.
The short answer#
Generating a maze involves thousands of coin flips. The seed is the starting point for all of them: an integer from 0 to 4,294,967,295 that the generator’s randomness flows from. Change nothing but the seed and you get a completely different maze; keep it, and the maze is reproduced bit for bit.
Same seed, same maze#
Everything random consumes one seeded stream in a fixed order — the generator’s walk, the search for entry and exit, even the cut that turns a maze into a single path. Nothing depends on the clock or the machine, which is why a recipe re-renders identically on any platform.
Where the seed lives#
You rarely type a seed. The studio picks one at random and records it in the maze’s recipe, so saving, sharing and forking all carry it along. The size and seed controls share a card — see Size & seed.
Reproducibility, by design#
Determinism is what makes a maze a keepable thing. A seed means a design is never lost to chance: the poster you printed last year can be re-rendered at a new size, exactly as it was.
