Performance Analysis

The Game Breaker Asym brings an asymmetric engine to Ebonite’s long-running Game Breaker franchise, pairing the V2 Asymmetrical Core with the GB 12.0 Pearl Reactive coverstock. The core numbers read strong but composed: a 2.48 RG that gets the ball into a roll by the midlane, a healthy .054 differential for big track flare, and a modest .008 intermediate differential. That last figure matters; it is enough asymmetry to define the breakpoint, but well short of the violent kick of higher mass-bias designs, so the shape stays continuous rather than skid-flip.

The cover preparation reinforces that controlled-strength idea. A pearl reactive finished at 2000 grit, with no polish listed, reads the lane earlier than the typical box-shined pearl, which is why the length rating sits at 6 despite the pearl base. Hook potential of 8 and pin action of 8 reflect what a .054 differential delivers when the core is allowed to do its work, while the backend rating of 7 describes a strong arcing finish instead of a sharp corner. Versatility at 7 makes sense for a sanded pearl asym: at home on medium to heavy oil, workable on fresh league shots, and responsive to surface adjustments in either direction.

Ebonite’s release footage, including the First 10 session with Tommy Jones, shows the intended picture: an early, heavy revving motion with a defined but readable move to the pocket. With a value rating of 8, the Game Breaker Asym delivers asymmetric performance without a flagship price tag attached.

Who Is This Ball For?

This is a piece for advanced bowlers who want asymmetric backend strength they can actually control. If you face medium to heavy oil in leagues or tournaments and prefer a ball that blends the pattern rather than yo-yoing at the breakpoint, the mild .008 intermediate differential and sanded pearl cover are a smart combination. It also works as the strong-but-not-dull anchor of a tournament bag, with the cover taking surface tweaks well as conditions change from block to block.

The cons are worth taking seriously. On lighter oil this much core and surface will read far too soon, and the 2000 grit box finish may need polish or some lane shine before it behaves on a typical house shot. Bowlers who want maximum length and a hard flip should look at shinier pearls instead. For players who value strong, continuous asymmetric motion on real oil, the Game Breaker Asym earns its 8 overall.

Ebonite has just released the newest addition to the GB line with the Game Breaker Asym. It has many of of the characteristics to the GB Pearl but they did a little modification to the core giving it a little asymmetry. I happen to have a lot of Asymmetric Pearls right now, so I drilled this a little different with a 4-1/2" pin under the ring finger. It is extremely clean & smooth. I do like the shape and and the way it pushes through the pins. Very nice add especially for league.

Game Breaker Asym is a polished pearl reactive with a small int. differential which gives it a little stronger move at the break. The surface gives it great length as expected, but the back end reaction with the stored energy causes the ball to go through the pins very well.

The Game Breaker continues to be the most trusted and popular lines in all of bowling. Ebonite has taken the Game Breaker line to the next level by shaving the sides off the core, creating the new Game Breaker Asym. With the core modifications it he;ps increase the intermediate differential to a medium .008. Which is just enough to see a defined difference when the shiny GB 12.0 Pearl cover sees the end of the pattern. Let’s be honest, it’s a Game Breaker! What more is there to say? A lot actually. In my opinion this is THE best GB ball to date. It allows you to play straighter or hook it more with these new modifications to the core. This GB will help you open up the lane and make it an easy transition into a Track Legion Pearl as the games go on. Moving left will become easier for you to do when you have this ball in your hand. It will also be a great upgrade for someone wanting a better ball than just the normal entry level reactive ball. Look for this ball to be one of the most sought after balls on the market. This is a perfect purchase!

This ball is as clean as they come! When the lanes break down, I can count on this ball to easily make it through the front part of the lane and make the turn downlane. This is quite a different shape than the other gamebreakers, but its unique especially for the Brands of Brunswick. It's a good ball for your bag as a step down from bigger pearls.

Bowler Stats: 18 mph (off hand), 420 RPM, Axis: 4 ⅞” right, ¾” up Ball: Ebonite Gamebreaker Asym Layout: 50 x 5” x 30 Surface: Box Review: Ebonite’s Gamebreaker Asym is a significant evolution in the GameBreaker line. The core designers at Ebonite set out to provide a slightly different shape within the GameBreaker line. By slicing off the sides of the V2 core, they were able to create a core that provided a medium degree of asymmetry (.008). This new design provides the ability to fine tune the ball reaction when drilling by controlling the placement of the mass bias but still maintains a low enough level of intermediate differential to not lose the downlane continuation that the GameBreaker series has produced for the last decade. The pearlized GB 12.0 cover provides a cleaner and sharper downlane ball motion compared to the GB4, which provides a natural complement as the GB4 starts to labor downlane during transition. When thrown against the GB4 the GameBreaker Asym was about 3-4 feet cleaner and about 3 & 2 weaker. This ball really begins to shine when you are looking to open your angles on medium oil or as the lanes are transitioning and still need the ball to read the midlane and roll through the back part of the lane. Summary: The GameBreaker Asym adds a new element to the extremely successful GameBreaker line. The new modified V2 core provides bowlers with the opportunity to fine tune their ball reaction when compared to the traditional symmetrical version of the core. The pearlized GB 12.0 coverstock provides more energy storage and downlane motion compared to Ebonite’s GB4. This ball finds its home as you need to create more angle through the front part of the lane or once a hook point has developed downlane. Utilizing this friction, provides a ball motion that clears the fronts with ease and allows the low rg/high diff core to read the mid-lane and roll through the back part of the lane. Rating: 9/10
