The goal is to make the maximum number of points, crossed out as many numbers as possible until the end of the turns (25) or using the 4 "pass" boxes.
Also there are some other rules to know:
* In each turn the player chooses the two white dice and marks a free cell, if it is an odd turn he can choose a colored dice and a white one.
* Choosing the two white dice we can cross out any color box with the sum number
* Choosing the yellow and white dice we can mark the box of the yellow row with the sum value.
* Once a number is crossed out, any numbers to the left of it cannot be crossed out in the future.
And this is more or less the game, this is a classic, enjoy it !
