First, drag a card from the tableau (the piles at the bottom) to the foundation (the piles at the middle) to decide the foundation base card.
Then, try to move all the cards to the foundation (built up in alternate colours, wrapping from K to A if necessary). The tableau piles should be built Down in alternate colours, also wrapping from A to K if necessary. An empty tableau can only be filled by a card from the waste pile (to the right of the covered deck). The reserve (the top right) cards can only be put to the foundation directly.
After opening all the cards from the stock, you can flip over and open again. But this time any waste cards must be used immediately.
