Small games enclosures (8)
I believe the answer is:
playpens
'small games enclosures' is the definition.
'playpens' can be an answer for 'enclosures' (playpen is a kind of enclosure). I am not certain of the 'small games' bit.
'games enclosures' is the wordplay.
'games' becomes 'play' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'enclosures' becomes 'pens' (pen is a kind of enclosure).
'play'+'pens'='PLAYPENS'
Can you help me to learn more?
(Other definitions for playpens that I've seen before include "Fenced areas for young children" , "Barred areas for young" , "Features in nursery" , "Enclosures for children" .)
