Skill shot: It's a two part skill shot. First part, there is an opto switch at the end of the long wireform on the right that leads from the shooter. You need to time when the ball crosses that opto with the animation on the screen. You gotta do the skill shot a couple times before you can get down the timing. Depending on where Chun-Li's bracelet hits on the bullseye determines the value of the second part of the skillshot.
Second part, the ball drops to the back wireform, then drops into the Blanka scoop. Bison will tell you to use the flipper and flash the lamp by the upper flipper. Ball ejects to the upper flipper. You need to hit the Bracelet Target that is opposite the upper flipper dead center. I forget the name of the target type, but it is designed so you can't just limp it or kind of graze it. It has to be a solid hit. If you miss, the shot becomes a hurry up where whatever you earned off of the first part of the skill shot starts counting down to 0.
TLDR: Plunge at the right time to get highest skillshot value. Hit the bracelet target to collect.
