Card game appears to be all right throughout (5)
I believe the answer is:
poker
'card game' is the definition.
(I know that poker is a type of card game)
'to be all right throughout' is the wordplay.
I cannot really see how this works, but
'right' could be 'ok' (OK can mean right or appropriate) and 'ok' is found in the answer.
The remaining letters 'per' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'appears' acts as a link.
Can you help me to learn more?
(Other definitions for poker that I've seen before include "Jabber" , "Rod liable to become heated" , "stud, say?" , "Fire rod; game" , "Fire iron and card game" .)
