Minecraft wiki entry for Seed_(level_generation), associated text: In Java Edition, the numeric entry for Minecraft seeds does not allow the number "0" (zero), as the game interprets "0" as a character, hashing it to its ASCII value of 48. However, by using a text seed for which the Java String.hashCode() function returns a zero value, the "zero seed" can still be used. Word strings that produce a zero seed include creashaks organzine, pollinating sandboxes, and drumwood boulderhead.[2] However, any text that hashes to 0 works, such as ddnqavbj, and 166lr735ka3q6, with zsjpxah being the shortest.
