A challenging game with simple rules. All cards start dealt face up and you build down regardless of suit, moving only single cards. Somewhat similar to Bakersdozen.
A three-deck version of Beleagueredcastle invented by Thomas Warfield. Since kings can only be moved to empty spaces or the foundation, opening up some columns is the key to the game, except there are 12 cards in each column that need to be gotten out of the way first.
Thomas Warfield's adaptation of a 19th century game first described in George A. Bonaventure's 1932 book of solitaire games. It is two-deck game where 52 cards start on the tableau and another 52 start in the reserve. Suits of cards are completely ignored.
