Yukon Solitaire

All 52 cards are dealt to the seven tableau columns at the start — there is no stock or waste. Pick up any face-up card together with every card stacked on top of it (the group does not need to be in sequence) and drop it onto a column whose top card is opposite color and one rank higher. Empty columns may only be filled by a King-led group. Move every card to the four foundations, ascending by suit from Ace to King, to win.
