    The Kingpin Rule is a bit of an enigma if you will. Usually when you find a ball that hooks soon enough to read on heavier patterns it likes to burn up as the pattern breaks down. The Kingpin Rule continues to come around the corner. This ball is very unusual in that it seems to read the lane correctly most of the time on heavier patterns. I have used it on a longer lighter volume pattern and a longer heavier volume pattern. This ball looked almost equally good on both. The Kingpin Rule has well above average energy retention for a ball in this category. Because of this, it also has gotten some use when our house shot has been a little tight. As far as comparisons go, it reminds me most of the original Mastermind with extra hook. I can see this being the heavier oil ball for most styles. Because of the extra energy retention, it also seems to carry the off hits very well. If you are looking for a great looking heavy oil ball with great potential check out the Kingpin Rule.

    A Hook Monster

    The Kingpin Rule is a really responsive, aggressive piece to add to your arsenal. If you're looking for shape downlane and the ability to see a ball read a higher volume pattern then this is the choice.

    I have mine pin over ring finger and out of box surface. I don't have a lot of ball speed but when you find the oil with this ball you don't have to worry about it not hooking. It has given me options with my angles that I didn't have before.

    The surface can be manipulated to create earlier or later motion very easily. I will say though, that I don't recommend this ball for low volume patterns or for burn squads in tournaments. There are far better Brunswick options for those challenges.

    Strongest, Greatest, Kingpin of ALL Kingpins

    Posted by Dwayne A. Jenkins on Jan 27th 2019

    The Brunswick Kingpin Rule is the strongest, hard-hitting, and early-rolling high performance ball to date, IMO of course. I really love the performance of this ball and the drilling that I used on this great performing arsenal (40 x 3.75 x 70) keeps me in play in league and tournaments for a great portion of my competitions. This ball rolls forward making pin carry a breeze and consistent for me. The Kingpin Gold SE makes a great companion for this arsenal and a perfect tag team for league play.

    KingPin Rule

    Another great addition to the Kinpin line, the Rule offers greater length and a sharper move than either of its predecessors. The Kingpin Rule comes with Dynamicore technology to increase hitting power and is the strongest Brunswick ball on the market. An ideal ball for those higher volume oil patters this ball is a must add to your KingPin arsenal.

    Wow, Just WOW

    The new Kingpin Rule is GREAT for those heavier or longer patterns. Also a great choice for those with a lower rev rate looking to get that extra backend motion. Out of box this ball is strong. It reads the mid lane great yet still retains energy to carry corner pins. The addition of DynamiCore assists with those "off" hits. If you are looking for a ball to combat the heavier or longer conditions, you cant go wrong with the Kingpin Rule.
