Rule Hunter Live

Every puzzle shows you a few solved examples. Your job is to work out the rule that turns one number into another — and then use it on the one that's missing. No timer is counting down. You have no lives to lose. A wrong answer just says so and lets you try again, as many times as you need. FIVE DIFFICULTIES Easy asks for a single step. Master asks for three, and hides the rule inside shapes that make you work out which number belongs to which before you can even start calculating. Each difficulty mixes several kinds of puzzle, so nothing turns into a routine. SEVEN WAYS TO HIDE A RULE • Rows — a number goes in, a number comes out • Symbols — fruit stands in for numbers, and you solve for what each one hides • Wheel — inputs and results sit around a circle, and each result is across from the number it came from, never next to it • Cluster — three numbers feed a single result • Octagon — four corners share four sides, and the missing corner is found by running the rule backwards • Triangle — two numbers meet and produce one • Sequences — each term is built from the ones before it EVERY PUZZLE HAS EXACTLY ONE ANSWER This is not a guessing game. Before a puzzle is shown to you, it is checked against the whole rule catalogue: if any other rule could explain the same examples but give a different answer, the puzzle is thrown away and a new one is built. What you see always has one defensible solution. AND YOU FIND OUT WHY When you solve it, the rule is spelled out in plain words. You never walk away from a puzzle wondering what the answer was supposed to mean. STUCK? Two kinds of help. "Rule" tells you the method and leaves the arithmetic to you. "Solution" simply gives you the number. WHERE YOU LEFT OFF Each difficulty remembers its own place.
