A Farewell to Kings 2.0.4 (Mac)
Source: Rob Steward Company
A Farewell to Kings is like no other solitaire you've ever seen. It plays more like a strategy game and is not easily mastered. In the game, the cards do not connect in the normal "linear" fashion. Instead, they connect two-dimensionally, by matching suits to suits and ranks to ranks. Attaching four-of-a-kind in a square formation completes a "book" of cards which can be removed from the board.
