Once you've pulled the aces off, flip over any facedown cards that are now exposed.Now take a look at the remaining faceup cards, excluding the ones in the finish piles.
For example, if you have a three of clubs faceup and a four of diamonds faceup, you can move the three so it sits on top of the four.
If you end up with a pile that becomes completely empty due to these actions, you can move a faceup king to that empty space.
If not, try to build tableaux, which basically means moving the faceup cards in the lower piles around.
The goal of the game is to get all of the cards faceup and moved to the finish piles.
