The game is fairly easy to understand: There are 5 dice: green, blue, orange, purple and 2x white. First you throw the dice. Now you have the opportunity to cross two numbers: - you can (but you don't have to!) cross the number, which is the sum of both white dice. - you can (but you don't have to!) cross the number, which is the sum of one (!) of the white dice and one (!) of the colored dice. Important to note is, that you don't have to cross every number in a row. Which means gaps between the numbers are possible. But you can't fill these gaps afterwards - The succession is from left to right! If you can't or don't want to cross a number in a round, you get a misthrow (-5 points). The maximum of misthrows is 4. The game ends with either the 4th misthrow, or when 2 arrays are closed. An array is closed, when the green / blue "12", or the orange / purple "2" has been crossed. This however, is only possible if there are at least 5 numbers crossed in that array. If an array is closed, you recieve an extra cross, which results in more points. So far this application is only played solo, but there will be an application in the future with multiplayer support.
