FreeCell game with 2 decks and 4 foundation piles. Like in the regular FreeCell: move all cards to the 4 foundation piles from Ace to King, wrapping to Ace and then to King again. There are 6 FreeCells (top left) where you temporarily can store 1 card.
On the tableau the piles are built down by alternate color. The top card is available for play on the foundations, cells, or another tableau pile. Move groups of cards if they are in sequence down by alternate color and if there are enough free cells that the cards could be moved individually. Empty spaces can be filled with any card or sequence.
