Dad's Solitaire

The goal of this solitaire game is to finish the same way you started it; with 52 cards in your deck. Originally, there are four empty columns and every time you deal a card is added at the bottom. The game ends when all the cards have been removed from all columns or when there are no more cards in the deck and no cards can be removed from the columns. There are three very simple rules by which cards are removed: a. The number of cards that are removed must be equal to three. b. The sum of the removed cards must be equal to 10, 20 or 30. c. The three cards must be contiguous.
