Just to clarify, is the minimal number of steps for each puzzle calculated automatically and guaranteed to be minimal, or is this a number that the author submits together with the puzzle (meaning the shorter solution might exist but the author is unaware of it)?
Great question! The minimum number is NOT calculated automatically and is decided by the community. You can earn โrecordsโ by finding a new minimum! This happens very often and sometimes players find new records from levels published years ago!
