Maybe you get an idea of the game...
Its a game about learning the basics of multiplication.
1x1, 2x1, 3x1, 4x1 ... (1,2,3,4...)
1x2, 2x2, 3x2, 4x2 ... (2,4,6,8...)
1x3, 2x3, 3x3, 4x3 ... (3,6,9,12...)
As you can see.. Some Numbers are in several rows...
What do you think? Is working with array easier than working with variables?
