The top exposed card on each column is flipped face up. To play, each player starts with their own 52 card deck and deals out 7 columns in front of them-the first column on the left has 1 card, the second column has 2, the third has 3, and so on.
Double Solitaire is a fun two-player variation of single-player Solitaire where players try to be the first one to play all of their cards on their foundation piles.
