Course must include permit for game (8)
I believe the answer is:
roulette
'game' is the definition.
(roulette is a kind of game)
'course must include permit' is the wordplay.
'course' becomes 'route' (I've seen this before).
'must include' means one lot of letters goes inside another.
'permit' becomes 'let' (synonyms).
'route' placed around 'let' is 'ROULETTE'.
'for' acts as a link.
(Other definitions for roulette that I've seen before include "Form of gambling" , "If Russian, it's a very dangerous game" , "Spinning-wheel game" , "risky venture" , "Gambling activity" .)
