Osmosis (also known as Treasure Trove) is a solitaire game played with a deck of 52 playing cards. The object, like many solitaire games, is to put the cards into foundations, although not in numerical order.[1] The name of the game reflects the fact that cards of the same value slowly filter through to successive foundations by osmosis.
Because winning the game relies on where cards are positioned in the reserve piles and in the stock pile, finishing a game of Osmosis can be difficult.
