A game with plenty to it (5)
I believe the answer is:
lotto
'a game' is the definition.
(lotto is a kind of game)
'plenty to it' is the wordplay.
I cannot really see how this works, but
'to' is found in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found within the answer.
The remaining letters 'lo' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'with' is the link.
Can you help me to learn more?
(Other definitions for lotto that I've seen before include "Children's game, housey-housey" , "form of gambling" , "house" , "Prize draw" , "Game of chance involving balls" .)
