Anyone who has played Sudoku will find the gaming system of Rullo very familiar. There is a matrix divided into several rows and columns, with certain values assigned to them. In each box there is a number. The goal is to 'deactivate' the numbers in the boxes which prevent the values in each column from tallying. The gameplay is easy to learn, but incredibly hard to master.
The best way to start playing Rullo is to practice with five-by-five matrixes. Then, once you are used to them, take the leap up to much more complicated matrixes of six by six, seven by seven, and even eight by eight. The larger, the more complicated.
Rullo is an ingenious and captivating puzzle game, which will have you hooked to your Android device for hours on end. Best of all, this is a game that lets you put your knowledge of math into practice.
