Quite simple. Find the odd one out, follow the instruction to give you a letter and then give me the code word.
Two pieces of advice first:
1) They gradually get harder (in my opinion)
2) Don't forget to check the tags!
i) Beijing ; Moscow ; Italy ; Vienna ; Sicily ; Shanghai (added to clarify)
(First letter - use this letter twice)
ii) O ; Q ; M ; S ; U ; C (added to clarify)
Hint:
This one is visual, not phonetic.
(use the odd one out)
iii) Flock ; Squabble ; Band ; Parliament ; Clowder (First letter)
iv) Monopoly ; Battleships ; Articulate ; Trivial Pursuit ; Scrabble
(Use the last letter)
v) Giraffe ; Horse ; Sheep ; Cow ; Bison
(First letter)
vi) H ; U ; C ; I ; O ; S ; Y ; W ; V ; K ; N ; B ; P (You need the letter that is missing)
vii) 4 ; 6 ; 17 ; 32 ; 50 ; 100 ; 101 ; 245
(Sum of digits minus one gives position in the alphabet e.g. 2 = A)
