Puzzle 5 - Foil
Complete the two sunflowers with four letter words spelt outwards from the central 50s, so that adjacent words differ by exactly one letter.
The example on the left shows how BANK can be changed to NOTE in four steps.
Once you have completed the sunflowers, find the central four letter word which differs by exactly one letter from each of the two words it’s connected to through the microchips, to solve the puzzle!
Use the letters one or two words ahead to determine which letters have changed in between.
Answer: BLOB

Here are two shared letters per word.
The first word to enter is JANMAAT as it’s the only one that fits in _ A _ _ A A T.
This then forces you to insert DOGMEAT, then CONTRAT, then BASTIAT
Answer: MARGOT

Puzzle 7 - Quotation
The clue is in the last line: “These lines twice show a supervisory ending“.
It’s
a bit like a cryptic crossword clue and you just need to look at the
ending of the last verse.
Just as an acrostic starts with letters that
spell out something, the final letters of each line spell out something.
Taking the last four letters of each line.
O V E R
E S E E
R I N G
O V E R
N S E E
D I N G
The letters that are doubled are
O, V, E, R, S, E, E, I, N, G
Answer: OVER SEEING

Puzzle 8 - Entscheidungsproblem
The sequence is 20,
8,
2,
10, 3,
7
20 + 8 + 2 + 10 + 3+ 7 = 50
£10 and
£20 are banknotes
2, 3, 7 are prime
2 < all other numbers
20 > 10 + 8
10 cannot follow 20
20 + 2 +
3 = 10 + 7 + 8
You can then “apply” your answer to the word ''Entscheidungsproblem''
20th letter m
8th letter i
2nd letter n
10th letter u
3rd letter t
7th letter e
Answer: MINUTE

Puzzle 9 - Signature
The key is that each letter A - T is followed by either (a) first number or (b) second number.
The only numerical information in the visitor book are the pairs is the entry and exit dates.
Max Newman's Visitor Book
O(b)
O(b) = Letter O on the LEFT
(a) sign IN date
(b) sign OUT date
(b) second number sign OUT date: 1 - 2
O(b) = 2, Q(a) = 15, C(a) = 12
R(b) = 5, J(a) =
25, D(b) = 14
A=1, B=2, C=3, D=4, E=5, F=6, G=7, H=8, I=9
J=10, K=11, L=12, M=13, N=14, O=15, P=16, Q=17
R=18, S=19, T=20, U=21, V=22, W=23, X=24, Y=25

Puzzle 10 - Crown
Start with the Queen. There is only one possible position, d7 (using standard chess notation).
a7, b7, d6, g8, h8 are impossible as they would be attacking the King. This leaves d3 and d7.
d3 is impossible as it rules out all the squares for the orange Knight therefore the Queen must be on d7. You can then rule out all squares attacked by the Queen from this position.
Next is the yellow Knight. a6 are b6 impossible due to attacking the King and the Queen so it must be on g5.
You can then rule out all Bishop and Knight squares that attack a piece you’ve already placed.

Puzzle 12 - Enigma
There are a lot of hints in the text of the question and it also
describes it as a meta puzzle.
The hints “count your change”, “cash in”, “change” make it clear there is a monetary aspect to this puzzle.
Next you probably will have noticed something about the words.
Many are remarkable close to names of British pre-decimal coins. Perhaps the easiest to spot first is FATHERING being very close to FARTHING. The only difference being a E – your “change”!
Then you just need to go through each word looking for an anagram for a
pre-decimal coin and a letter left over as “change”.
Then, as the question asks, you need to “cash in your answers in increasing order” so work out the value of each answer and sort them in ascending order to get the following.
FARTHING ¼d (FATHERING) – change =
E
GROAT 4d (MARGOT)
– change = M
TANNER 6d (LANTERN)
– change
= L
BOB 1/- (BLOB)
– change = L
FLORIN 2/- (FJOLNIR)
– change = J
CROWN 5/- (CORWEN)
– change
= E
NOBLE 6/8 (BOLEYN)
– change =
Y
LAUREL 20/- (CRUELLA)
– change =
C
SOVEREIGN 20/- (OVERSEEING)
change= E
UNITE 20/- (MINUTE)
– change = M
GUINEA 21/-
(EUGENIA)
– change = E
