I grew up in Mass and we had a Candelpin Bowling alley in my town. We used to go a few times a year, normally for a birthday party or similar event. Its tough. Bowling a 100 in Candlepins was an accomplishment. They tore down the alley when I was in High School so the only bowling available was the next town over where they had "Big Ball Bowling."

I never watched it much, but they used to have televised Candlepin Bowling show on a local chanel called "Candlepins for Cash." They would bring on a few local bowlers to try their luck on the Candlepin lane to earn cash based on their score. If I recall correctly, they used to have a bonus pin that was painted red that lead to extra cash if you knocked it down.
Of course, when I went "big ball bowling" the first time, I had no clue what I was doing. luckily we had someone in the group who bowled 10-pin so he knew all the differences. I grabbed the ball with my thumb and first two fingers in a totally incorrect grip and bowled away. My first night with the Big Ball, I rolled a 179 with a bad grip. I have never approached that number again since.

That incorect grip lead to me flipping my wrist around on the transition from backward swing to forward swing and I would end up releasing the ball with my hand on top of the ball with a wrist flick. The ball would almost float down the lane like a knuckle ball with some backspin on it and then catch the lane with some left to right movement (from a right hand release). Very poor technique, but it was consistant.
