Diavolo Solitaire
The objective of the Diavolo Solitaire game is to move all the cards to the 8 foundation piles. 4 of the foundation piles start with A and are built up by cards of the same colour to K.
2 of these foundation piles are built with red cards, and the remaining 2 are built with black cards.
The remaining 4 foundation piles are built down by alternate colours from K to A, and can only be filled in when all 13 cards are ready.
The tableau piles can be built down by alternate colours, and the top cards that are correctly stacked can be moved together as a group.
Empty tableau piles can only be filled by K.
