I join two hundred in a game that's played (7)
I believe the answer is:
piccolo
'that's played' is the definition.
I can't tell whether this defines the answer.
'i join two hundred in a game' is the wordplay.
'join' means one lot of letters go next to another.
'two hundred' becomes 'cc' (roman numerals).
'in' indicates putting letters inside.
'a game' becomes 'polo' (polo is a kind of game).
'i'+'cc'='icc'
'icc' put within 'polo' is 'PICCOLO'.
Can you help me to learn more?
(Other definitions for piccolo that I've seen before include "High wind instrument" , "Smallest of the flute family" , "Instrument of the flute family" , "producer of note" , "Part of 14 [ORCESTRA]" .)
