Dice Charlie removed put an end to children's game (9)
I believe the answer is:
hopscotch
'children's game' is the definition.
(playground game)
'dice charlie removed put an end to' is the wordplay.
'dice' becomes 'chop' (I've seen this in another clue).
'charlie' becomes 'C' (phonetic alphabet).
'removed' is a deletion indicator.
'put an end to' becomes 'scotch' (I've seen this in another clue).
'chop' with 'c' removed is 'hop'.
'hop'+'scotch'='HOPSCOTCH'
(Other definitions for hopscotch that I've seen before include "Playground game" , "kids jump about in it" , "Children's game with squares on ground" , "Children's pavement game" , "Traditional children's game" .)
