Cleaner given odd address as a game? (8)
I believe the answer is:
charades
'a game?' is the definition.
(I know that charades is a type of guessing game)
'cleaner given odd address' is the wordplay.
'cleaner' becomes 'char' (char can mean a cleaner).
'given' says to put letters next to each other.
'odd' indicates alternate letters.
The alternate letters of 'address' are 'ades'.
'char'+'ades'='CHARADES'
'as' acts as a link.
(Other definitions for charades that I've seen before include "Party guessing game" , "Games like this" , "Game in which answers are acted out" , "Miming parlour game" , "Miming games" .)
