# Create an array of zeros which has four columns and two rows
zero_array = np.zeros((2,4))

# Create an array of random floats which has six columns and three rows
random_array = np.random.random((3,6))

# Create an array of integers from one to ten

# Create your scatterplot

# Create the game_and_solution 3D array
