Deja Vu Rail Solitaire
A more challenging two deck version of Rail Solitaire. With Deja Vu rules rather than having eight foundation piles you only have four (one per suit). Those foundation piles build from Ace to King and then again from Ace to King.
Totally free. No in-app purchases.
DOUBLE RAIL - the classic game.
DOUBLE SLEEPERS - a version with cache spots.
SQUARE - an oddball version where the tableau surrounds foundation.
