Osmosis Solitaire

Osmosis is a solitaire card game with unusual game play which is played with one deck of standard 52-cards set. The aim is to move all cards to four foundation piles by suit in any order.

RESERVE - Four cards each are dealt face down to four reserve piles. Top card is turned faced up.

FOUNDATION - One card is dealt face-up to one of the four foundation piles.

STOCK - Remaining cards are set aside forming a stock pile.

WASTE - Empty waste pile.

  • One card dealt to first foundation pile sets suit for that pile. Remaining three foundation piles can have other three suits.
  • Top card of a reserve pile can be played to the foundation. An exposed card in the reserve pile is turned face up.
  • When no move is possible, cards can be dealt 3 at a time from the stock to the waste. Top card of the waste pile is available for play. Unlimited redeals are allowed.
  • In the first foundation any card of same suit can be played. In any of the other 3 foundation piles, only cards with those ranks can be played which have already been played on the foundation pile one above it. Other 3 foundation piles can be started with any card of the other 3 suits as long as that rank has already been played to the foundation pile just one above it.

The game is won once all cards are moved to the foundation piles.

  • Drag and drop cards between two piles.
  • Single/Double-click a card to automatically move to the foundation.
