This game is played with a standard pack of cards and can be played as a solitaire or by any number of players. Each player has a 5 by 5 array. As the cards are called each player either puts a card or writes the corresponding number in one cell of the array. (Kings are entered as 13, Queens as 12, Jacks as 11 and Aces as 1). When the 25 cells are filled the players score each of the rows and columns and the two main diagonals according to the scoring table. The highest score wins.
In the example given the pair of 5s is worth 10 points in the third row and the pair of kings on the diagonal are worth 20 points and the total score is 570.
