ludo

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

'board game' is the definition.
(I know that ludo is a type of board game)

'played out loud' is the wordplay.
'loud' anagrams to 'LUDO'.
But, I am not clear how this is indicated.

Can you help me to learn more?

(Other definitions for ludo that I've seen before include "Simple board game, involving dice" , "Type of board game" , "Children's board game" , "Race game" , "Traditional board game" .)
