crispy

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

'game likely to crack?' is the definition.
I can't judge whether this defines the answer.

'king spotting' is the wordplay.
'king' becomes 'CR' (short for Carolus Rex, King Charles in Latin).
'spotting' becomes 'ispy' (I can't justify this - if you can you should give a lot more credence to this answer).
'cr'+'ispy'='CRISPY'

Can you help me to learn more?

(Other definitions for crispy that I've seen before include "Tender and brittle" , "Crunchy, brittle" , "Dry, brittle" , "being invigorating" .)
