We recently went to the Orange County Fair and saw all of the "Games of Skill" on the midway. After seeing what looked like an intelligent man drop $18 on the basketball toss game (and not even get the $10 stuffed animal,) I decided to check on the legitimacy of these games.
According to a Contact 4 investigation by KRON-TV, the games aren't rigged, just really hard and not worth the money.
An expose of different types of carnival fraud, including how that dart and balloon game works:
A dart-the-balloon game has some very desirable prizes on display. To win, you're told you have to throw a dart, burst a balloon, and the tag under the balloon tells which prize you've won. What you don't know is that no tags show the desirable prizes. They all show the cheap prizes, called slum. You spend a dollar for three darts and you walk away with a plastic comb that cost the game operator less than a nickel.
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
