Crossword Solitaire

In this game you need to use 49 cards to create a 7 by 7 grid of cards. The number cards are like spaces in a crossword puzzle and the face cards (J, Q, K) are like black squares. The cards are first shuffled and form the stock cards. The first stock card is dealt to the center of the table and the game starts. Each time you put the top card from the stock cards to a place that is adjacent (horiztonally or vertically or diagonally) to one of the cards on the table. When putting the cards, observe three rules: 1) two face cards must not be adjacent to each other (horizontally or vertically); 2) if all 7 cards in a row or column are filled, then those 7 cards (face cards excluded) must sum up to a even number; 3) the cards between two face cards or between a face card and the boundary of the crossword must also sum to a even number. If you manage to fill in 48 of the places, then you can uncover all the remaining 4 cards and choose one that can fill in the remaining space. The more cards you manage to put, the higher your score.
