Accumulate stakes (4)
I believe the answer is:
pool
I believe this is a double definition.
'accumulate' is the first definition.
(thesaurus)
'stakes' is the second definition.
(I've seen this before)
(Other definitions for pool that I've seen before include "Ball game - small body of water" , "Small body of still water" , "Organization of people or resources that can be shared" , "Game played on a table with six pockets" , "game indoors" .)
