Fortress

Rules of the game

Objective

To move all cards to the foundations.

Layout

Four Foundation piles, initially empty. Start building by moving an Ace to the empty foundation, followed by 2, then 3 and so on until King. Each foundation accepts cards of the same suit in ascending order only (UP IN SUIT), i.e. once you play the Ace of Spades on a particular foundation, you may only play 2 of Spades on that foundation, then 3 of Spades, upto the King.

Ten Tableau piles, the first two are dealt 6 face-up cards, while the remaining get 5 face-up cards. Cards can be played onto the tableaux if they are either one rank below or one rank above and the same suit (BOTH WAYS IN SUIT) of the topmost card of the pile, i.e. if the topmost card is 10 of Spades, then either 9 of Spades or Jack of Spades can be played on that pile. Only the top card of a Tableau may be moved. Double-clicking the topmost card of a tableau pile will send it to the foundation. This is a shortcut for the sometimes tedious drag-and-drop. An empty tableau may be filled by playing any card onto it.

Tips

This game is difficult to win because only one card can be moved at a time on the tableau.
