Poker Squ♠res

This is a game similar to the Poker Solitaire found in Casino/Poker Plus. The
object is to place twenty-five cards out of fifty-two on a grid five rows wide

get.

Points are awarded in the following way:

* For each row with one pair: one point
* For each row with two pairs: three points
* For each row with three of a kind: six points
* For each row with a straight: twelve points
* For each row with a flush: five points
