Introduction
In any Pick 4 game, there are 4 digit positions, with each position containing a digit from 0 to 9. If one were to list all of the possible combinations of digits in each of the three positions, there would be a total of 10,000 different number combinations. Each of these 10,000 possibilities is called a straight combination.
