These games are a cross between the popular Klondike and Spider solitaire games. All versions are free-to-play. No in-app purchases.
Each game inherits the classic ramp starting position and objective (move cards onto the foundation) of Klondike, but the tableau builds like Spider (down in mixed suit but groups of cards can only be moved if they are matching suit).
SPIDIKE - More Cards deals one card to each column.
TRIANGLE 3-CARD - Cycle through the deck three cards at-a-time as many times as you wish.
TRIANGLE 1-CARD - Cycle through the deck one card at-a-time exactly once.
