Don't forget, once you collect at the scoop and exit out of CIU, you can collect another 25% of your collected jackpot after you complete all spider arrows and hit the Mystery scoop again. This opportunity lasts until you lose the ball.
Example: If you collect 100 mil when choosing to exit CIU, and then when you go back to regular gameplay, if you hit all 6 lit spiders, you can go back to the scoop for another 25 mil. This only carries over during the same ball, and it doesn't matter whether you have started another MB, FUEL, S&D, Blackened, or Lady Justice. If you hit all six spider shots one time each on the same ball you were on when you exited CIU, you'll collect another 25% of that collected jackpot.
