University gets kudos, having cracked this puzzle (6)
I believe the answer is:
sudoku
'this puzzle' is the definition.
(I've seen this before)
'university gets kudos having cracked' is the wordplay.
I cannot really see how this works, but
'university' could be 'u' (abbreviation for university) and 'u' is found within the answer.
an anagram of 'kudos' is 'sdoku' which is within the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for sudoku that I've seen before include "Number game" , "(Usually) nine-by-nine numbers puzzle" , "Numeric puzzle" , "Puzzle involving the numbers 1 to 9" , "Numerical puzzle" .)
