Move all cards to the Foundations.
The playing piles build down by alternate color, and an empty space can only be filled by a King or a sequence starting with a King.
When you click on the Talon, one card is turned over onto the Waste pile. There is no limit to the number of times you go through the Talon.
You are also permitted to move cards back out of the Foundations.
