Description of the Krypto Game

Krypto is a card game designed by Daniel Yovich in 1963 and published by Parker Brothers and MPH Games Co. It is a mathematical game that promotes proficiency with basic arithmetic operations.

Krypto is played with a deck of 56 cards: three each of the numbers 1 through 6, four each of the numbers 7 through 10, two each of the numbers 11 through 17, and one each of the numbers 18 through 25. There is an option that can be checked to ignore the standard card distribution and allow any two-digit values to be used.

Brief Krypto rules

Six cards are randomly dealt number side up, with the sixth card being the objective card. You then must ONLY add, subtract, multiply, or divide using each of the the five playing cards just once to obtain a result that equals the number on the objective card. Negative numbers and fractions are not allowed anytime during the calculation. See some examples below.

Example 1:
Cards: 2, 1, 2, 2, 3 = 24
A possible solution: (((2+1) * 2) + 2) * 3 = 24
2 + 1 = 3
3 * 2 = 6
6 + 2 = 8
8 * 3 = 24

Example 2:
Cards: 24, 22, 23, 20, 21 = 1
A possible solution: (((24+22) / 23) + 20) – 21 = 1
24 + 22 = 46
46 / 23 = 2
2 + 20 = 22
22 – 21 = 1

Example 3 (Very rare impossible Krypto combination):
Cards: 6, 9, 19, 20, 22 = 12
Sorry, no solution found.

Example 4 (Invalid solutions from other solvers)
Cards: 19, 11, 11, 13, 23 = 14
Invalid solution (11-13)*(23-(11+19)) = 14.
Yeah, the equation is valid but using negative numbers such as (11-13) is invalid.
