Scorpion Solitaire is a column based solitaire card game, somewhat similar to Spider Solitaire. It's only played with a single deck and suits matter. You have to build the cards into 4 columns that go from King to Ace by suit. All but 3 cards are dealt out at the beginning of the game. At any time those 3 cards can be dealt into the first 3 columns by clicking on the deck at the bottom of the game screen. You can move the columns from any card that is not face down, but you have to move all the cards that are below the card you grab in the column. You also can only move the card you grab onto a card that is of the same suit and has a value one greater than the card you are moving.
