boules

I'm a little stuck... Click here to teach me more about this clue!

'game of mixed doubles unstarted' is the definition.
I can't tell whether this defines the answer.

'mixed doubles unstarted' is the wordplay.
'mixed' indicates an anagram.
'unstarted' means to remove the first letter.
'doubles' with its first letter taken off is 'oubles'.
'oubles' is an anagram of 'BOULES'.

Can you help me to learn more?

(Other definitions for boules that I've seen before include "French form of bowls" , "Petanque" .)
