Point among squares in game (8)
I believe the answer is:
ninepins
'game' is the definition.
(I know that ninepins is a type of bowling)
'point among squares in' is the wordplay.
'point' becomes 'p' (abbreviation).
'among' becomes 'in' (eg among or in a group).
'squares' becomes 'nines' (I've seen this before).
'in' means one lot of letters goes inside another.
'p'+'in'='pin'
'pin' placed into 'nines' is 'NINEPINS'.
(Other definitions for ninepins that I've seen before include "Bowling targets" , "Skittles, IX objects to be knocked down" , "Form of skittles" , "Skittles (IX, not V)" , "Bowling game" .)
