puzzles

The puzzle section of the book (First edition, PDF, 518kb) was produced with the aid of a number of free on-line puzzle generators:

Easypeasy anagram generator
Makepuzz word search
Truman Collins' alphametic puzzle generator

The title of the section, reproduced above, is in the form of an ambigram, or word formation that reads identically upside down.

Errata

1. Major contours at elevations of 2000, 2100 and 2200 were displayed on the map on page 121 as if they were minor (thin lines). The map in the PDF copy shows only major contours, as the 20m contour data is not yet generally available from Geoscience Australia.

Partial Solutions

Solutions should never be given freely: it just encourages people to give up too easily. The sections below provide clues, hints or additional puzzles to unlock the real solution. If you really get stuck (and care enough), mail me.

Anagrams

For most people, solving non-trivial anagrams without a pretty good idea of what the word or phrase is can be extraordinarily difficult. Once you know the knowledge domain (movie titles, capital cities, Pink Floyd tracks etc) though, the usual technique is to think of possible phrases based on length and a few unusual letters in the anagram, and try to match letter-for-letter.

To help you apply this technique (a lot), here are the twenty answers, unscrambled, but in alphabetic order. My apologies for using the obsolete spellings of Rennix Gap and Swampy Plain River.

Crossword

Crossword solutions are usually shown with the correct letters in the correct places. How boring. You should always have to discover knowledge, not have it presented on a platter, requiring no effort at all on your part.

Hence the grid below contains the solution to the crossword, but encrypted by a simple substitution cipher and reflected about its vertical centre line. This means that

  1. Each correct letter has been replaced by another letter, using a fixed substitution rule (see below). You have to invert the rule to decode each letter.

  2. The answers run right to left.

The substitution rule is a rotation of the alphabet. For example, the "D" rotation replaces "A" by "D", "B" by the next letter, "E" and so on. It's easily illustrated by writing the alphabet on one line, and another copy below it, shifted so "D" is below "A". The three letters to the left of "D" are moved (rotated) to the end under "X Y Z":

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
D E F G H I J K L M N O P Q R S T U V W X Y Z A B C 
For the encoded solution below, the rotation amount is given by the first letter on page 53 of the book. You should thus
  1. Find the letter
  2. Write the rotated alphabet below the normal alphabet here
    A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
    
    
  3. Decode the grid from right to left by looking up each encoded letter in the bottom row and reading off the corresponding letter in the top row.

Of course, you don't really need the book at all, as any correct letter in your partially completed crossword enables you to discover the rotation amount.

Alphametic Puzzles

The alphametic puzzles were omitted from the second edition due to space limitations.

No complete solutions, only possible answers for the sum, which gives most of the letter assignments. The others are readily determined.
