Osmosis |

1 Deck. Medium (32%). Mostly Luck. Object To move all the cards to the foundations. Layout
• | 4 foundation piles (center) - build each foundation in suit, regardless of order. On the top foundation, any card of the same suit as the first card dealt may be played. On the lower foundations, start with a card of the same rank as the first card dealt, then play any card of that suit where a card of the same rank has already been played to the foundation immediately above.
• | 4 reserve or tableau piles (left of foundations) - top card is available for play on the foundations. At the start of the game 4 cards are dealt to each pile, the top card is face up.
• | stock (face down, right) - Turn over cards one at a time to the waste pile. Unlimited redeals.
• | waste (below stock) - The top card of the waste pile is available for play on the foundations.
Notes
• | Play consists entirely of playing cards to the foundations.
• | For example, suppose the first card dealt to the first foundation is the 10♥. Then any ♥ from the reserve or waste could be played to the first foundation pile. Suppose you can play the Ace, Five, and King ♥. The 3 foundations below must be founded with the other 3 Tens, as they become available. Suppose the 10♠ is available. It is played to start the second foundation. Then only the Ace, Five, or King ♠ could be played to the second foundation, since these are the only ranks in the first foundation pile. Suppose the Ace ♠ can be played to the Second foundation. Then in the 3rd foundation, first a remaining Ten and then only the Ace of the same suit could be played. The effect is that the ranks filter down through the foundations by "osmosis", hence the name of the game.
History Osmosis is also sometimes called "Treasure Trove".
