How Do You Get the Secret Strike in the Wii Sports Resort 100-Pin Game?

In order to get the Secret Strike in the 100-Pin Game of Wii Sports Resort, the ball must be rolled very close to either the right or left gutter guard; its position should be set with the D-pad so that the dotted line is almost parallel with, but ever so slightly aimed into, the gutter guard, and maintained on this course right to the end of the lane. Upon reaching the end, the bowling ball will activate a red button, which in turn will cause an earthquake, toppling all the pins down at once.
