Off bingo, we're all doing strip poker (6)
I believe the answer is:
finger
'off bingo we're all doing' is the definition.
I can't tell whether this defines the answer.
'strip poker' is the wordplay.
'strip' becomes 'fin' (fin is a kind of strip).
'poker' becomes 'ger' (I can't explain this - if you can you should give a lot more credence to this answer).
'fin'+'ger'='FINGER'
Can you help me to learn more?
(Other definitions for finger that I've seen before include "Touch; select" , "Fringe (anag.)" , "Slender part attached to the hand" , "Sort of bowl" , "Part of one's 10" .)
