Halloween Scorpion Solitaire is a version of Scorpion Solitaire with a festive Halloween theme.
If you're a fan of Spider Solitaire, Scorpion is another fun column based solitaire card game. With Scorpion, you can pick up the row of cards at any point in the column, but you have to build down the columns by suit instead of disregarding suit as you do in Spider Solitaire. There are a total of 8 cards that are flipped over so you can select them or see what cards they are. There are also 3 cards that haven't been dealt out yet, and you can deal those cards out at any time by clicking the deck.
It's usally a good strategy to try and flip over the 8 cards that you have their back side up as soon as you can. Also, if you end up with a few Aces on the top of your column, you can get rid of them by moving the columns to the left three columns then clicking the deck to deal another card over them.
