Game taking place over in borders of Pakistan (7)
I believe the answer is:
pontoon
'game' is the definition.
(I've seen this before)
'taking place over in borders of pakistan' is the wordplay.
'taking place' becomes 'on' (as in a phrase like 'the event is on now').
'over' becomes 'too' (I've seen this before**).
'in' is an insertion indicator.
'borders of' means to remove the middle letters.
'pakistan' with its middle removed is 'pn'.
'on'+'too'='ontoo'
'ontoo' put inside 'pn' is 'PONTOON'.
(Other definitions for pontoon that I've seen before include "Lighter" , "Floating bridge support" , "Bridge of boats" , "Gambling game" , "Vingt-et-un" .)
