Queen finally confined to large old house (5)
I believe the answer is:
bingo
'house' is the definition.
(I've seen this before)
'queen finally confined to large old' is the wordplay.
'finally' indicates one should take the final letters.
'confined to' indicates putting letters inside.
'large' becomes 'big' ('big' can be a synonym of 'large'**).
'old' becomes 'o' (common abbreviation eg in OE for Old English).
The last letter of 'queen' is 'n'.
'n' inserted into 'big' is 'bing'.
'bing'+'o'='BINGO'
(Other definitions for bingo that I've seen before include "Number-calling game" , "Popular gambling game in which numbers are called at random" , "Lotto" , "Housey-housey" , "Number game" .)
