Sticky game? (6)
I believe the answer is:
hockey
'game?' is the definition.
(hockey is a kind of game)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for hockey that I've seen before include "SPORT/GAME" , "Game started by a bully!" , "It's played with curved stick" , "Game with a bully-off" , "Sport involving curved sticks, a ball and goals" .)
