Allowed to get in the way in the game (8)
I believe the answer is:
roulette
'game' is the definition.
(I know that roulette is a type of gambling game)
'allowed to get in the way' is the wordplay.
'allowed to' becomes 'let' (to let something happen is to allow it).
'get in' is an insertion indicator.
'the way' becomes 'route' (route is a kind of way).
'let' going into 'route' is 'ROULETTE'.
'in the' acts as a link.
(Other definitions for roulette that I've seen before include "sort of gambling" , "SPORT/GAME" , "Gambling activity" , "it's for the better, supposedly" , "Gambling game with spinning wheel and ball" .)
