Cards must be moved one at a time. The only cards you can move are:
A card in a Freecell.
The last (bottom) card in a Column.
(A card played to the Foundations cannot be moved thereafter.)
Looking at the first Column in the layout pictured above, the 7 of Hearts may be moved but the 8 of Clubs may not — and so on, for all the Columns. Cards in Freecells are movable, so the 6 of Spades and the 7 of Clubs may be moved.
