You first must get at least one free spin. On your seventeenth spin,
you will be asked if you want to use a free spin. When this happens
click Yes with the Left Mouse Button. Repeatedly click on Yes as
fast as possible until it disappears. Notice that your free spins will
be a negative number. All four of your spins will now be free, even if
you only had one free spin.
