I believe the answer is:

supports

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

'stays' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Maybe you can see a link between them that I can't see?

'up when there are games about' is the wordplay.
I cannot really see how this works, but
'up' is found in the answer.
'games' could be 'sports' (I've seen this before) and 'sports' is found within the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for supports that I've seen before include "Backs up, bears out" , "Tees" , "Helps" , "Backs or approves of" , "Holds up" .)
