In order to play a game of Bingo, you will need a “Bingo Sheet” and a caged globe full of small white balls with numbers printed on them. Since we are working with Javascript on CodeHS, we will forgo the cage and balls in favor for a random number generator.

The random number generator will have a ‘Spin’ and a ‘New Game’ button at the top of the screen. If the user presses ‘Spin’, then a unique random number will be generated and printed to the screen in a large font. If the user presses ‘New Game’ then ‘Spin’, all the numbers called thus far become irrelevant and a random number will be picked from 1-70. The random number generator will have a growing list of numbers that have been called. Remember, the numbers that are picked cannot repeat themselves.

Take a look at the image below for an example of how your Bingo Number Picker should look. Remember to check with the rubric to ensure that you are receiving all your points.
