Spring put an end to kid's game (9)
I believe the answer is:
hopscotch
'kid's game' is the definition.
'hopscotch' can be an answer for 'game' (hopscotch is a kind of game). I'm not sure about the 'kid's' bit.
'spring put an end to' is the wordplay.
'spring' becomes 'hop' (hopping is a kind of springing).
'put an end to' becomes 'scotch' (I've seen this in another clue).
'hop'+'scotch'='HOPSCOTCH'
Can you help me to learn more?
(Other definitions for hopscotch that I've seen before include "child's play" , "Traditional children's game" , "Children's game with squares on ground" , "Playground game" , "Jumping game" .)
