The game is about finding the hidden mines. Each box you click on will either show a number of mines around each box or a mine. If there is no number it means that there is no mine around it. You can put a flag by right-clicking anywhere you think there is a mine. If you click all the boxes without clicking a mine, you will win.
In the below section of code I used jQuery to animate the start button and get the values of the numbers of mines and columns. I had to change the width of my boxes for different screen sizes using jQuery, so if the user inputs a larger number of columns, it will automatically change the size of the board.
