Cryptic CrosswordsEach clue will contain some form of wordplay, as well as a standard definition. The two parts together may provide a deceptive meaning. The key to solving cryptic crosswords is recognising where the two parts separate – which is standard definition and which is wordplay.

Missing Cubes These puzzles test your ability to judge three-dimensional depth intwo-dimensional images. How many cubes are missing from each block?

Cube Sums Using the same principles as above, cube sums require you to work out how many cubes make up each stack – remember that perspective can be misleading and some rows of cubes may continue, unseen, behind others.

AlphameticsEach letter represents a number between 0 and 9. If solved correctly, the result should be a valid arithmetic sum. Throughout the sum, each letter will always represent the same number, and no line can begin with the number 0. Unlike conventional addition, it is easier to work from left to right.

EXAMPLE We know that any two four-figure numbers cannot add up to more than 19,998 (9,999 + 9,999). So, we know that the M in the answer is 1. This tells us that the M in ‘MORE’ is also 1. To find S we must use addition. We already know that S+M (or S+1) equals 10 or more. We can only use digits 0–9 and, knowing that M is 1, S can only be 9 in order for 1 to be carried across to the next column, ie. 9 + 1 = 10. Therefore, O must be zero. Using this technique, try to figure out the rest of the puzzle.

Money Puzzles Hone your numerical agility skills by juggling with deduction, division, multiplication, subtraction and all the tools of puzzle logic.

HOW MUCH EACH?

Sally, Linda and Eric have $28 between them.

Sally has twice as much as Eric, who has twice as much as Linda.

How much has Eric?

TONY’S GUITAR

Tony sold his guitar at an Internet auction.

He had to pay the website $3 to list his guitar and 10% commission from the price achieved at auction.

The buyer paid $25, which included $6 postage and packing.

As Tony originally paid $20 for the guitar, how much had he lost?

JOHN’S LUNCH

John noticed the amount he was paying for his lunch was a rearrangement of the digits of the amount of money in his pocket – and that the money he had left was a further rearrangement of the same three digits!

How much did he start with?

ICE CREAM MONEY

Tom had twice as much money as Sally, so he paid for the 10c ice creams for himself, Sally and Alice. That left him with twice as much as Alice, and half as much as Sally. Luckily, they found a cent on the footpath, so they just had enough money to catch the bus home.

How much was the bus fare?

Logic PuzzlesSome of us arrive at solutions via the detective route, others use instinct. These puzzles will improve your powers of both analysis and reasoning.

Rebuses Words are represented in these puzzles by combinations of pictures. Use lateral thinking if you are struggling – it helps to think ‘outside the box’.

to have a ball.

WEIGH IT UPYou are given 12 balls and are told that one of them is lighter or heavier than the others. You have a set of scales (but no weights) and have three weighings to establish which ball is the odd one out and whether it is heavier or lighter than the others. How is this done?

What am I? What phrase is depicted below?

Riddles It is said that the earliest riddles were presented as oracles. In ancient times, riddles were mainly about the sun, moon, rainbows and the wind.

GUESS WHAT?My first is in earlier, also in later.My second’s in tyrant, but not in dictator.My third is in break, but not in repair.My fourth is in circle, but never in square.My fifth is in deep, but not in profound.My whole travels with you, quite close to the ground.What am I?

THE NAME GAME My first is in add, but not found in take.My second’s in fillet, but never in steak.My third is in stack, but not in a heap.My fourth is in thick, but never in deep.My fifth is in veal, but not found in lamb.My sixth is in ounce, but never in dram.My seventh’s in smile, but not in frown.My whole is a writer of highest renown.Who am I?

KIDNAPPED This is a true story from Taiwan. A rich man’s son was kidnapped. The ransom note told him to take a valuable diamond to a phone booth in the middle of a public park. Plainclothes police officers surrounded the park, intending to follow the criminal or his messenger. The rich man arrived at the phone booth and followed instructions – but the police were powerless to prevent the diamond from leaving the park and reaching the crafty villain. What happened?

ANGRY WORDS Think of words ending in -gry. Angry and hungry are two of them. There are only three words in the English language. What is the third word? It’s something you use every day. If you read the riddle carefully, you’ll find the answer within it.

Miscellaneous PuzzlesEach of the following puzzles presents a different type of challenge. You don’t need special knowledge to solve them, just clear, analytic working.

TRICKY LETTERS

E4 O6 R3 C9 L5 G7 I8 P1What letter/number combination is missing?

MISSING THREE

The numbers 4–16 have already been placed into the square almost, but not quite, at random.

Following just two simple rules, where would you place the numbers 1,2 and 3 in the square?

LEVEL PEGGING

Transfer all of the discs from Peg A to Peg B following these rules:

Rule 1: You may take discs off a peg one at a time only and put each disc on another peg, but never in such a way that a disc is put on top of a smaller disc.

Rule 2: You must finish with the four discs in the same position on Peg B as they are now shown on Peg A.

Rule 3: The transfer can be achieved in 15 moves. Can you figure out how?

C: In all the others dark blue is opposite black, green is opposite red, yellow is opposite light blue, purple is opposite light brown. In C, black is opposite light blue and yellow is opposite dark blue.

E: Working clockwise; A has the same coloured sequence of dots as D and B has the same as C.

A: Looking across each line, numbers progress +3, –1, +3. Looking down each column, they progress +1, –3, +1.

73542: Reverse the previous number each time, but deduct 1 from the middle digit.

48: Multiply the digits in each number to obtain the next number in the sequence, for example; 2 x 3 x 9 x 7 = 378 and 3 x 7 x 8 = 168.

The numbers indicated by the red line are in the sequence 1, 3, 5, 7, 9, 11, 13, 15. The numbers indicated by the blue line are in the sequence 16, 14, 12, 10, 8, 6, 4, 2.

HOW MUCH EACH?$8: Linda has one share, Eric two, and Sally four. That makes seven shares in all. $28 ÷ 7 = $4. So, Linda has $4, Sally $16, and Eric $8.

TONY’S GUITAR $5.90: After allowing for postage, the buyer paid $19 for the guitar. 10% of this was commission ($1.90), and Tony had to pay the listing fee ($3), so he actually made $14.10. As he originally paid $20, he had lost $5.90.

ICE CREAM MONEY36c: If the difference between double Sally’s money and half Sally’s money is 30c, then Sally must have 20c. So, Tom has 10c and Alice 5c, a total of 35c. With the penny they found, the total fare must be 36c, 12c each.

JOHN’S LUNCH $9.54: The money can be written with just three digits – so must be between $1.01 and $9.99. Trial and error shows that there is only one set of numbers that fit this question: $9.54 = $4.59 + $4.95

WEIGH IT UPThere are several solutions. Here is one. Weigh four balls, call them A, B, C and D, against four balls, E, F, G and H. a) If they balance, then the rogue ball is I, J, K or L. So weigh I, J and K against A, B, C. (i) If they again balance, weigh L (the faulty ball) against any other ball to find out if it is heavier or lighter. (ii) If they do not balance, you know if the odd ball is heavier or lighter. Weigh J against K to identify which of I, J or K is the odd ball.b) If A, B, C and D go down, then weigh A, B, E against C, D, F. (i) If they now balance, G or H must be lighter. Weigh them against one another, or either one against a true ball, will establish which. (ii) If they still go down, then A or B must be heavy or F is light. Weigh A against B to establish which. (iii) If they now go up, then C or D must be heavy or E is light. Weigh C against D to establish which.c) If A, B, C and D go up, the identical tests (with reverse conclusions) will again establish the odd ball.
