It's time to start building games! Let's display the countdown from three to one and then display Go!,  just like in a real racing game. 

To put it in the right order, drag and drop the lines where they belong and hit Solve.

Great job! Now the lines of the code are in the right order.

If the computer executes the commands line by line, we have to start with 3, continue with 2, followed by 1, and finish with "Go!", no?
