Osmosis

The object of the game is to build up columns of cards along the top right.

All columns must be started with cards of the same value, which is determined by the first card that has been dealt into the first column. For example, if the first column is started with a four, then all other columns must start with a four.

Once started, other cards can be placed in a column provided they are of the same suit as the other cards in the column, and there is a card of the same value anywhere in the column immediately to the left. For example, you cannot place a ten in the second column until the ten of the appropriate suit has been placed in the first column.

Cards can be taken from the deck (which is dealt three cards at the time), or from one of the four piles that each contains four cards at the start of the game.

The game is won by moving all the cards from the deck and the four piles of cards to the columns.
