Game to help others (7,5)

'help others' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'game' is the wordplay.
I cannot really see how this works, but
'game' could be 'match' (eg a football match) and 'match' is found within the answer.
The remaining letters 'charity' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'to' acts as a link.

Can you help me to learn more?
