# Seedle

> Roll one random Minecraft seed a day and score emeralds for whatever generated in the 2048x2048 blocks around the origin.

Minecraft is deterministic. Know the seed, know the world, without ever generating it.

Seedle rolls one random seed a day and scores what's in the 2048x2048 blocks around the origin:
structures, biomes, world spawn. Everyone gets the same seed that day. It resets at midnight Eastern.

The scan is exact. It runs cubiomes, the reference C implementation of Minecraft's generation,
against 1.21.3. Nothing is sampled or estimated. Paste a seed from here into Minecraft and you get
the same world.

There are 111 rules, listed below. Hit one, get paid in emeralds. Rare ones pay more, and
the rates aren't invented: every rule is sampled over hundreds of thousands of seeds and priced off
the measured rate. A day's total lands on Minecraft's material ladder (coal, copper, iron, redstone, lapis, gold, emerald, diamond, netherite). Those
cuts come from the real distribution of daily scores, so a median day is lapis.
