House for some is one grand game (5)
I believe the answer is:
igloo
'house' is the definition.
(I've seen this before)
'some is one grand game' is the wordplay.
'some' indicates taking the first letters.
'one grand' becomes 'g' ('G' can be a synonym of 'grand').
'game' becomes 'loo' (historic card game found in Jane Austen novels).
The first letter of 'is' is 'i'.
'i'+'g'+'loo'='IGLOO'
'for' is the link.
(Other definitions for igloo that I've seen before include "A house up north" , "Traditional Inuit house" , "Inuit residence" , "Home made of blocks of snow" , "Eskimo's dwelling" .)
