Number String - 1.0.6

6 cards are dealt face up. The player tries to combine some or all of the first 5 cards to equal the value of the sixth card. Players may use any combination of addition, subtraction, multiplication and division. Up to 2 pairs of parenthesis may be added if desired. The cards and parenthesis use a "drag and drop" style interaction. Because multiple solutions are often possible, the scoring system encourages the use of as many number cards as possible. The value of each card used to construct a solution is added to achieve the players score. Using multiplication and division operations earn additional points. Besides acquiring points, each time an equivalency is completed a "hidden" background picture is displayed.
