Size is the grid size which will be a certain amount of grid spaces. For example: size 12 would be 144 spaces. Number range means the length of the numbers. For example, number range 46 would mean that a grid space can have a number from 1 to 46 and the ball can roll from 1 to 46. Then click the submit button to start the game with the given settings. Click to roll a number and the marks will happen automatically. Unfortunately, the board does not sense BINGOs so you will have to use your imagination when you when.
Thanks to Microsoft for the font "Arial Rounded MT." Marks are a bit buggy.
