MarbleBox is a twist on the classic game MineSweeper. With MarbleBox, it's not enough to just open the 'empty' boxes; now you have to actually pick how many marbles are in the unopened one by using logic, deduction, and reasoning. When an empty box is opened, it will reveal numbers around it. Those numbers tell you how many marbles are within a radius of 8 squares. With that information, you should be able to figure out how many marbles are in each box. The goal is to open all of the empty boxes without opening the boxes that contain marbles.
