Block Solitaire is two deck solitaire card game where the player is dealt 12 cards into 12 piles to start the game. The player can build down these piles without regard to suit, but can only move the top card in any given pile. The player must build up the 8 foundations from Ace to King by suit to win the game. When all the cards from one of the piles have been removed, the pile is automatically started again with a card from the stock pile. If the player gets stuck, he can at any time deal a new top card to each of the piles from the stock pile, by clicking on the deck at the bottom of the game screen.
