Figures it's a game (5)
I believe the answer is:
fives
'game' is the definition.
(fives is a kind of game)
'figures it's a' is the wordplay.
I cannot quite see how this works, but
'it's' could be 'es' ('e' can mean 'electronic' which is similar to 'IT') and 'es' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for fives that I've seen before include "Squash relative" , "bunch capable of causing injury?" , "Small numbers" , "Game similar to squash" , "Ball game" .)
