Game that may be decided in the end (5)
I believe the answer is:
bowls
'game' is the definition.
(I know that bowls is a type of bowling)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for bowls that I've seen before include "Game; vessels" , "Kitchen pots for storing" , "Rolls smoothly along the ground" , "Lawn game" , "woods" .)
