Tree solitaire is a special form of solitaire in which cards are laid out as follows:
Row one- One card
Row two- Two cards
Row three- Three cards
Row four- Four cards
Row five- Five cards
Row six- Six Cards
Row seven- Seven cards
All rows are laid out such that they cover half of the cards in the row immediately above, so that the end results resembles a tree to a degree, thus the name.
During play a player pulls the top three cards from the deck and flip them face up. If less than three cards are left when the end of the deck is reached then the difference should be ignored and the cards flipped as usual, so that if two cards are left then only those cards are flipped, the player may not wrap around to the front of the deck to get a third card. Only the top card can be played, the cards below can be played if the card(s) above them can are removed.
The object is to remove all cards from the tree by combining two cards to have a total face value of 13. So if your third row was: 9 J K; and had no cards on top of it, the king could be removed on its own, the jack would need a two, and the nine would need a 4. Suit is irrelevant, as is color.
The player may only go through their deck three times. If the player is unable to eliminate all cards in the tree and has reached the last card in their deck then they have lost.
This game is really a variant of pyrimad
