Will o' the Wisp Solitaire
Will o the Wisp is a one-deck version of Spider. Cards can be stacked on the tableau in mixed suit but must be in matching suit sequence to be moved as a group. The objective is to create full runs of suited cards.
You can play a 1-Suit, 2-Suit or 4-Suit version. All games are totally free. No in-app purchases.
In Fair Maids you build the tableau down in alternate color suit. It is played with a standard deck of cards.
