Miss Milligan is a two deck game that features something no other game does, a temporary cache column. The eight tableau columns start with one card in each column and when you run out of moves you deal one more card to each column. The temporary cache comes into play once you have dealt all the cards to the tableau. At that point the cache column becomes accessible and it can hold one card or one in-sequence group of cards.
Cache is the same game with four cache spots where you can store single cards for later use.
Imperial Guard allows for any card to fill an empty column, not just Kings.
Imperial Guard Cache is Imperial Guard with four cache spots.
Both games are free to play. No in-app purchases.
