NumberChase: Let the Chase Begin

NumberChase is a very exciting game which requires quick mind and even quick fingers.

The aim of this game is to select exactly two dice that add up to the number which is randomly generated in the middle of the four dice. But there is one constraint, you only have a few seconds to do that. It may happen that out of the four dice, none of the two dice add up to the random number that is generated, in that case wait for the next number to be generated.
