Easthaven Solitaire, originally called Aces Up Solitaire, is a common card game played with a 52-card deck of standard playing cards and goes back to at least the early 1930's.
It's kind of a cross between Spider Solitaire and Klondike Solitaire.
It's claimed that an average player can win about 25% of their games and a good player from 40% to 50%.
The game requires some level of skill to do well; however, a good part of the game is luck. It's not uncommon to be dealt a randomly generated game where the player has no appreciable chance of winning.
The goal of Easthaven Solitaire is to build all 4 ordered suits from the ace to the king in the foundations.
When the game starts, a pile of 3 cards is dealt into each of the 7 tableau columns, of which only the top card in each pile is face-up and visible. The remaining 31 cards are sent face-down to the stock.
Within the tableau, cards are built down by rank in alternating colors. An ordered run or any length may be moved from the bottom of one pile to the bottom of another pile, but always the target card must be both next in rank to the top card being moved and of the opposite color.
When the last card is removed from atop of a hidden card, it's automatically brought into play by turning it face-up. When all cards are removed from a pile, its column is then empty. A vacant column may be filled with any ordered run of one or more cards.
In order to build suits, the player can move one card at a time to the foundations. If the card is an ace, it begins a new build, if not, it must be next in rank for its suit. A card is allowed to be moved from the foundations to the tableau, as long as it's to a legal location.
When there are no more useful moves to be played, the players click on the stock. This sends a face-up card into each column, or just 3 on the last deal. No card can be moved to the stock.
The process of moving cards and dealing new ones continues until all of the cards have been dealt from the stock. The game is now won if the player can move all of the remaining cards from the tableau to the foundations, else the game ends when the player decides to discontinue play.
Here are a few tips on how to win at Easthaven Solitaire:
The game screen is made up of 3 separate areas.
The tableau is located in the center of the screen. It consists of 7 columns. Each column either contains a vertically overlapped pile of one or more cards or is empty, depending on the current state of the game. This is where pretty much all the action takes place during gameplay.
The foundations area is located above the tableau. It consists of 4 rectangles. Each rectangle is a foundation where a suit can be built from the ace to the king.
The stock is located in the upper corner. This is where the reserve cards are held that are put into play as the game progresses. At the start of the game the cards in the stock are face-down and squared. In order to deal from the stock, the player must click on it. This causes a face-up card to be dealt into each of the tableau columns, except for the last deal which deals what's left.
