ABSTRACT
Nothing says you have to try to solve a puzzle by starting with the premise, then working straight toward the answer. Often starting from the end—“retrograde analysis” is the fancy term for it—will make things much easier. (Are you among those that think solving a maze any way other than by drawing a line from “start” to “finish” is tantamount to cheating? That’s fine if that makes it more fun for you, but I advise against applying this strategy to every puzzle.)
