welcome to our dark code showcase brand new ball from storm products releasing july 2nd before we get started make sure you hit that sub button because it's really important to us the channel and i'll love you forever all right let's get started new ball carry we're not like most channels we have access to things that many people do not or we think ahead years ago i was collecting bowling balls and i knew that on this day i'd be

comparing the dart code to the code black red and x i had one of these in my closet so punched them up i'm going to compare them for you today and hopefully you'll like the video yeah yeah i was tired [Music] at least the dark code strikes a lot making me feel a little better just like the rest of the domestic code balls and all code balls this ball has the rad4 core it's got a brand new cover r2s and an nex blend first time this

cover's ever been used nex obviously really strong cover found on the proton all the code balls all have r2s just pearl hybrid and solid what i'm expecting this one to be is somewhere either between the red and the x or stronger than all of them if prepped at the same surface of course this is a pretty strong bowling ball because the rad4 core is really strong and nex is also really strong as i proceeded to miss the headpin almost falling on a ten to one house

shot we've been blowing on it for about two and a half hours now so they're getting a little clip we're gonna scoot a little to the right just to show you guys how much more they're hooking when you get it there [Music] so i moved like three with my feet sparked it really quick so i think we're going gonna be playing somewhere in between those two spots so we're gonna test the versatility of the dart code and throughout the video we're gonna be trying to strike from every arrow so i'm sure you guys have seen a seven arrows

challenge before it's gonna be a little tricky arrow number one [Music] i have for you a code black here shout out casey he got this for me for my birthday i

don't know why he got me a bowling ball for my birthday because i get bowling balls for free but thanks anyways so i'm gonna play that in between slot like i was saying i'm gonna expect the code black to hook the least because it's the weakest set of all three but there's plenty of hook big cliff cliff medium cliff big clip falling on big cliff [Music] this definitely isn't the ball that i would choose right now being a big cliff

and it's a pearl ball i like the strong engine the core that's really good for blending out clips but i think the cover's just a little too weak okay the two arrow we like to call this black jack stand 20 hit 10. all right six more shots i ain't missing ice in the veins

that's two baby we never miss on this channel we're gonna try the code red hybrid cover stock should read a little bit earlier we're gonna throw one from about the same spot hopefully this one rolls through the pins a little better that one rolled through the pins a little better but that tells me i'm still too close to the friction on this cliff i got to keep going if you have this problem where you're too close to it and it hooks too much when you get it there you just have to keep going until you have a little bit of wiggle room

all right number three oh that's disgusting gonna jump a few more boards to the left and make sure our ball speed stays on the softer side [Music]

all right middle of the lane we're halfway there [Music] we don't miss all right couple more boards at the feet we're gonna try to get a break point in a little bit so we don't feed it to the friction too fast [Music] so yeah i got that one about the whole arrow left of the last one didn't quite pick up but throw the codex in that spot should be perfect

i found that one to the right but we're finally in a spot where we have a little bit of room so i'm gonna throw one more hopefully keep it online i feel like i should go in front of the bar return for this more angle more prob i mean strikes i might have to throw it a little slower

i think this is going to be the hardest arrow because from in front of the ball return i can throw it slow enough and it's i'm hitting up on it enough so it's taking a lot of speed off it [Music] what does rob like to say yahtzee what a guy all right we're going to play the same part of the lane do with the codex but with the dart code and this is why this ball is going to be the best ball to come out since sliced bread

going off the deep end maybe oh the cliff is so prominent you

is it the best code ball domestically of all time i don't know is it going to be the best ball of all time i don't know is it pretty good i think so there can only be one code one please strike [Music]

[Music] seventh arrow a lot of loft action here [Music] oh that was so close [Music] it's funny because i throw it more and more i just feel like it starts to look less and less

i'm done i'm done get me out of here

Performance Analysis

Testing revealed the Storm Dark Code to be an exceptionally strong reactive pearl that sits at the upper end of the domestic code ball lineup. Independent reviewers observed the ball on a house shot pattern after approximately 2.5 hours of lane conditioning, where it demonstrated significant hook potential and a prominent backend reaction. When compared directly to the Code Black and Code Red in identical spots, the Dark Code exhibited noticeably more aggressive motion through the pins, particularly when positioned in the mid-to-heavy friction zones. The RAD4 core—shared across the code family—combined with the newly introduced R2S NEX blend coverstock produced a ball that required careful board management; testers found they needed to move several boards left to accommodate the ball’s strong recovery and avoid over-hooking into the friction too early.

The versatility testing across multiple starting positions showed the Dark Code’s strengths and limitations. On direct headpin lines and lighter angles, the ball’s strong engine and reactive cover created the kind of backend aggression that produces carry. However, testers found the most reliable strike line required positioning with adequate room to manage the ball’s hook potential—overshooting into heavy friction resulted in deflection rather than drive through the pocket. Adjustment strategy focused on moving the breakpoint further down the lane to give the ball more skid length before it engaged the friction, which proved more effective than throwing harder. The R2S NEX blend’s aggressive surface characteristics became more pronounced as conditioning progressed, suggesting this ball will continue to read friction strongly in longer practice sessions.

Who Is This Ball For?

The Dark Code is built for bowlers who command good speed control, understand angle management, and bowl in medium to medium-heavy oil conditions. This ball rewards players with the rev rate and consistency to execute controlled movements; it’s not a forgiving ball for inconsistent release or erratic speed variation. Bowlers who enjoy strong-reading cores and reactive pearl covers—and who typically play in the oil rather than chasing dry boards—will find the Dark Code’s aggressive motion profile intuitive. It’s best suited for league and tournament bowlers with established fundamentals who want a premium piece designed to read friction decisively.

This is not an ideal entry point for developing bowlers or those still learning angle and speed management. The Dark Code demands respect for its strength; testers found that casual adjustments or slight speed variations created noticeable carry or deflection swings. However, for experienced players looking for a second or third ball in their arsenal—particularly those who own weaker pearls or need an aggressive asymmetric piece for oil—the Dark Code’s performance ceiling makes it a legitimate investment that will reward precision and technique.

The Dark Code is an extremely strong, dynamic asymmetric pearl from Storm. With a 2.50 RG, .058 differential and .020 intermediate differential in 15 pounds, this ball wants to get going once it sees friction and do a lot of it. I went with a 45x5.5.25 layout on mine, which tamed down a little of the flare potential but still retained enough of it to keep a great shape down the lane. I found it very easy to just roll off of my hand and not have to force it to not hook early. If it sees early friction in the mids, for me, it did want to stand up and go left off of it. The good thing being, I did not get to a point where I was too far left, getting as far as 6th arrow and still striking on the used house condition I was on. I can see this being a fantastic choice for medium to high speed bowlers, as well as bowlers of all rev rates. The ball seemed to be most comfortable left of 15, for my style. I had to be extremely precise with my hand position playing close to the dry as it wanted to hook immediately. This will be a great ball to play the track to begin with, then continue to move left all night with. Another great piece from Storm!

Storm Dark Code Rg. 2.50 Diff. 058 Int. .020 The Dark Code is the modern version the Code black. If you loved the Code Black or any of the code series balls, you will fall in love with this piece. The Dark code responds harder than any of the current balls down lane but it is still controlled and predicable. The layout is 6 x 4 x 2, because the core is so strong, I still need the ball to get down lane. I definitely recommend using weaker pin to pap distances to see the full hook potential of this ball. The shiny black cover stock has such great shelf appeal and everyone needs to get their hands on one.

The ultra popular RAD4 core is back and this time it features a brand new cover formula ReX, which is NeX and R2S combined. I drilled mine 5.5 x 5 x 1 and for comparison purposes, I compared it to the Roto Grip RST X-1, which I have also drilled the same way. After throwing the Dark Code, I was quite amazed on how strong this ball was and how much it continued to angle down lane. It is just a couple boards strong than the RST but the shapes of the ball are totally different. The RST is a lot more of a smoother angled shape into the pocket, where the Dark Code you can see the cover dig in and once it makes its motion it doesn’t quit. I can see myself using this ball later in blocks on longer patterns where I still need a strong but angular motion.

The new Storm Dark Code brings back the Rad 4 Core from the original Code Series balls but with a new enhanced pearl coverstock the REX. The REX Coverstock is a combo of the NEX and R2S coverstocks to form a new reaction that gives you the strong midlane read of the NEX cover with the angular backend of the R2S cover. This coverstock and Core combination give quite a unique reaction in the Storm Lineup. Not only can this ball handle oil, but it still gives you the backend you expect from a Storm Pearl ball. For me, I would use this ball on heavier oil house patterns or on high volume sport patterns of various lengths. This ball is a good step down from the Proton Physix or Incite which will give longer length and more angle in the back end. If you have/had a Code Black, you will see a stronger midlane motion in the dark code while still giving that same angular backend motion. Compared to the Parallax Effect, the Dark Code will again give you an earlier read on the lane while providing a slightly more angular back end motion.

We have a new iteration of the Code series with the Dark Code. Similar to the other Code balls the RAD4 core is utilized featuring a RG of 2.49 and a high differential of 0.056. The cover is a new formulation called ReX. What I like about the Dark Code is it is earlier compared to the Code Black. For those who found their Code Black to be a bit too long the Dark Code will be the perfect solution to counter that. This ball will be a great step down off the stronger asymmetrical and solid balls or even some of the solid hybrids. The Dark Code will allow you to open up the lane and create plenty of entry angle.

As always, I would like to thank Storm for providing the equipment I use every time I step out onto the lanes and Logo Infusion for making sure I always look good no matter what! Today I will be bowling on a standard medium volume house shot. The Dark Code features the Rad 4 core found in all the previous code balls but is now wrapped in REX pearl. This direct quote from Storm explains the design intent behind the Dark Code. “Some bowling balls immediately sink their teeth into the lane in order to provide traction in oil. Others glide through the front part of the lane with ease, saving all their energy for an explosive backend reaction. But, what happens when you have a ball that’s capable of offering both?” What this boils down to is a high differential and lower RG core that wants stability as soon as you release it wrapped in a higher friction pearl cover. The REX cover takes the best characteristics of R2S, known for its longevity and versatility as well as a quicker response time from steeper angles; and combines it with the insane traction NEX produces. I’ve found that the Dark Code is truly the best of both worlds. I am able to trap the ball with closed angles and still have it slow down enough to blend the friction and with a small hand position I can open up my angles and allow the ball to respond faster off the friction once the pattern is more developed. I was able to use the Dark Code for the first time on a 47’ 3:1 sport pattern games 2-6 and it looked fantastic the whole time. Two days later in league I was able to throw it on our fresh house shot and started off with a spare then rattled off 14 in a row. When compared to the Parallax Effect, the Dark Code is a touch longer and more responsive down lane. Compared to the Axiom Pearl, the Dark Code is earlier and stronger overall.

Coverstock: ReX (Reactor Extreme) Core: RAD4 Core Finish: 1500-grit Polished RG: 2.50 Differential: 0.058 Intermediate Diff: .020 ME: Right-Handed Tweener Speed: 12-13 mph Rev Rate: 315 PAP: 4 7/8 Right 3/8 Up Ball Layout: Pin over Ring 65 X 5 X 25 DUAL ANGLE 5 X 5 X 1.5 VLS Storm's new Dark Code features a brand new coverstock formulation. The blend of NEX and R2S covers puts this ball in a unique spot in the line. Wrapping it around the RAD 4 core teams up a monster core with an incredibly dynamic cover to create big hook and a very unique read of the lanes. NEX being the absolute top of the line in midlane read has created some of the most powerful balls on the market lately. R2S is the legend that keeps coming back because it seems to be a guaranteed winner no matter what core you use with it. The blend of these two covers has created motion that almost feels like an optical illusion. The Dark Code isn't early, but it sees the midlane. It's not snappy but you can't really call it overly smooth either. What it seems to do is give you midlane motion that never really seems to stop. The powerful RAD4 core gives it a big engine so you end up with a polished ball that is useful when there's oil on the lane, but doesn't slow way down. This allows you to keep the great continuation through the pins as you move left, without ever really losing the ability of the ball to see the mid-lane. My first experience with the Dark Code was in league. To combat the summer heat the house had juiced up the middle of the lane a bit. This made them super cliffed because of how much the outside hooked. No problem for the Dark Code, it blended them perfectly. I was honestly very surprised that I was able to throw it because I usually end up struggling to get stronger balls down-lane on the house shot. I also often struggle with the weaker balls being a bit unpredictable because there is so much dry to the right. Dark Code opened up more area than I think I've ever had on that shot. It allowed me to control the backend without sacrificing carry. I also had the opportunity to throw the Dark Code on a 44 foot challenge pattern. It was fantastic in the middle games where I would normally struggle in the transition. I was amazed at how much "get back" this ball had on the longer pattern. I felt like I easily had the most miss room right on our pair. This is a ball that is a must for tournament bowlers. When you need to overpower more oil and have confidence on how your ball is going through the pins, this is the ball for you.

The Dark Code features a brand new REX or (Reactor Extreme) Pearl reactive coverstock with the RAD4 Asymmetric Core made in the popular Code Series.. The Dark Code has a low RG of 2.50 a high differential of 0.058 and a low intermediate differential of 0.020. To bring this all together, the REX coverstock is a combination of the popular NEX coverstock with R2S. The NEX coverstock seen in the Axiom and Proton Physics and the R2S we have seen in the Astro Physics and IQ Emerald. The Dark Code is going to give you a very smooth roll very clean through the midlane and save all its energy for the backend. It will allow you to get left to right very easily. The layout chosen was a 75 x 3 ¾ by 80 which will give the ball a medium entry angle to smooth out the wet/dry on a house shot that’s either seen right away on the fresh or in the transition games. I did a ball comparison to the 900 Global Zen, Storm Code Black and Strom Trend on the 42 foot Stone Street pattern First up is the 900 Global Zen, the Zen is the hottest ball on the market for Global right now and as you can see the Zen blends the midlane very well with the S77 Response Cover, Meditate Core and reacts very strong off the spot for a symmetric ball. The Zen is 3 & 2 stronger than the Dark Code. Next is the Code Black, the Code Black and Dark Code have the same numbers, same core but the Dark Code has a different coverstock additive. The addition of the REX with R2S really shines here because you see how the Dark Code is stronger by 1 to 2 boards then the Code Black. The big difference you will see is how much sooner the Dark Code reads the midlane verses the Code Black. The last ball in the comparison portion of the video is the Storm Trend. The Trend has the R2S coverstock as well with a symmetric core but the Trend rolls very similar to an asymmetric core on how it changes direction very quick with the Piston core with a corkscrew type motion. The Dark Code is at least 2 boards stronger than the Trend. In my bag, the Dark Code can be a first out the bag or at very close second to the RST X-1 when its starts to burn up and leave flat tens. A ball down to the Dark Code could be a Trend or a Hustle PBR.

Diff: 0.020 (15lb) Tester Axis Tilt = 12° • Testers Rev Rate = 325 Tester PAP = 5 1/8 R, 1/2 D • Tester Axis Tilt = 12° •Testers Rev Rate = 325 Layout =4 x 4 x 2 Test Pattern = 42’ THS • Modified, Kegel Stone Street The new Storm Dark Code delivers a uniquely solid and robust ball to your arsenal. With the combination of RAD4 Core and the new ReX Pearl coverstock, Storm has once again hit a winner! Let's take a look at how the Dark Code handled a THS. The new ReX Pearl cover was surprisingly aggressive on fresh oil. While looking up the ten board, the ReX Pearl cover read very well in the mid-lane and gave me a predictable look I could depend on. Coming off the pattern, I was impressed with how much this ball loves friction. It displayed a crisp turn off the pattern but was also smooth and continuous! As I moved inside, looking fifteen to eighteen, I liked how this cover allowed me to move the breakpoint. I didn't see the "jump" or erratic movements you tend to see as conditions break down. It's not often a box finish works for me, but the 1500-Polish surface on the ReX Pearl suits my game quite well in various THS patterns and various houses. I am a big fan of Asymmetric Cores, and the bigger, the better. And the RADCORE4 is just that - big and powerful! The RADCORE4 motion is well suited for a lower rev, high-speed player like me. It revs reasonably early for an asymmetric, yet it has an authoritative movement that gave me the strong impact I depend on. I like how RADCORE4 retains its energy to the pocket. And when it unleashed its fury, the carry potential was fun to watch! It always feels good when those pins simply seem to fall! My conclusion is that the Dark Code is an effective ball for your arsenal. The Dark Code will deliver for you night after night for speed dominant and lower rev rate players. In addition, the Dark Code will score for you on any THS pattern, especially when there is a large volume of oil! I highly recommend this ball for any player like me. Trust me – you will enjoy the Dark Code's benefits. So see your local Pro Shop operator today and enjoy the rewards of owning a Storm Dark Code.
