Officially noted as available to play (2,6)
I believe the answer is:
on record
'officially noted' is the definition.
(I've seen this in another clue)
'available to play' is the wordplay.
'available' becomes 'on' (on can mean activated or available).
'to play' becomes 'record' (I can't justify this - if you can you should believe this answer much more).
'on'+'record'='ON RECORD'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for on record that I've seen before include "where needles used to be put" , "officially acknowledged" , "Publicly known - stated in published document" , "Officially recognised" , "Officially noted" .)
