Some video used belongs to the PBA and is used under fair use
This is very high effort, great video!
Wow! I never thought in a million years I would come across a comment I left over 3 years ago featured in a bowling video 1:41
As soon as you started talking about that strategy, I thought about that this comment since I normally never leave comments then BOOM it appears on screen 🤯🤯🤯 you cant make this up 😂😂😂 thank you for the very detailed video, and for helping the bowling community abroad. I love seeing our sport grow 💪
Kingpin for the win!!!!
thats insane.
yo that’s cool
@@awesomedino51 right? 😭😭 i am still flabbergasted
@ not only did he use the 3 year old comment, but this video also found it's way to you, pretty crazy odds
This video is a major contribution to the sport! I love the statistical analysis. Meaningful sample size too. Good work!
I got it once accidentally when I was a new bowler. I'm a slower speed right handed bowler, and all I was trying to do was get the 7 pin, it very slowly rolled over to the 10 and knocked it down. I was so new, that I didn't even appreciate how rare that happens.
When you pulled out the graph for the ball return or wall for which to shoot at my mind was blown. Only 2 minutes in. Definitely earned a subscriber, super underrated
sheeeeeshhhhh
There's definitely something to factor in here, something with the Brunswick A, Jetback, and A2 machines is that the odds of making it increase if the curtain is inverted, it makes pins bounce more off the back, that's also when you see people sending crazy deadwoods out of the machine, and on the AMF 82-70s and newer of the curtain is partially down where you can see the top of the pin wheel that upper part can bounce pins more just like an inverted curtain on the A line machines
I wonder if too much bounce makes it worse as the bounced pin can more easily fling forward from the other pin, Packy from The House Bowling and Brent did a video where they kept getting bounceouts on the Brunswick A but were unsuccessful getting a pickup after many attempts.
I've picked it up 8 times (and once bouncing it out the gutter). The consistent factors for me were speed and how directly I hit the pin. At my house it is better to hit it off the wall, and I used that as a factor for shooting at it. I normally throw a 15lb ball at about 19mph when shooting straight at the 10-pin, but am able to hit 24mph with a 13lb house ball and so I default to that when shooting at this.
Great content!
Thank you!
Absolutely love the analysis and breakdown on this! Well done.
Great video!
Fascinating! Great work!
Wow nice work man
Nice breakdown. I’ve made it twice ever, both times in an odd circumstance too. #1, sometime in the late ‘90s: at practice, ended my game by leaving the 7-10 on the fill shot, but back then, our AMF machines didn’t sweep it away, so I got a free shot at it. Cross lane at 10 pin, hard and straight. Caught just inside of center, and the pin kicked out of the corner, and rolled across the back of the deck and took the 10 out. Two witnesses too :) . Had also made the 8-10 three times at the same center, same way. This house (RIP) had lots of bounce outs. #2, August ‘24: practice again, and to get loose, the first five frames I always shoot at just the 10 pin, because I suck at making it. Shot #7 (at a full rack this shot), I see the ball is gonna pick the 10 pin clean, so I turn and walk away. I get back up to shoot, I see the 7 is also gone and is in the left gutter! So for this one, the ball hit the 10 just outside of center, hit the back cushion, then deflected off the ball and off the cushion again to take the 7 out. AMF machine again (ball return on 10 side), 16.61 mph throw with a 14 lb 25-year-old ball. I got a pic of the 2 count on the scorer and one of what was left on the deck. And this “conversion” was the ONE TIME I didn’t video record my practice in the last few years. Recap: I’ve made this twice now and have never been awarded a spare for it. LOL.
7-10 Split aahhh this is a nice one.
So here is the thing:
To convert 7-10 it is really easy depends on the Machine Type you are playing.
The easiest Method on a free Fall Pinsetter is the KF3000 from FUNK Bowling. After that you have the AMF Pinsetters, than the Brunswick A-2 and at least the Brunswick GS-X.
Of course the most shots are luck, but like you mentioned in the Video, you can increase your chances by hitting both of them with the opposite Ball Return Side. (This is not necessary on A2 Machines, because the ball gets shot back from the Middle but for AMF and GS-X Pinsetters I agree.
AMF and A-2 Machines with the Cushion Board on the Back can be a possibility to increase pin reaction by installing it very hard on AMF Pinsetters of you switch the sides and put the Cushion backwards into the A-2 Pinsetter. This makes pins more bounching in the Back.
I have a Video I can give to you on a KF3000 Funk Pinsetter using a 10lbs Houseball. I needed 8 Shots for converting this Split on this type of machine.
Regards Chris (Bowleasy)
This is great information. Thanks for putting it together. Subbed.
converted mine shooting at the 10 and bouncing it off the back wall over to the 7 and kicking it out of the gutter. threw it 18mph as well. I did make it opposite the ball return too which is neat to see after you pointed that out. Great video.
HE HAS RETURNED!!!!
Content I never knew I needed! Great video!!!
with the amount of diagrams sed in this video, i could tell this took a LOT of research and time. Very underrated, keep up the good work
YES A NEW VIDEO BRO IVE BEEN CHECKING LIKE EVERYDAY U NEEEED TO DO MORE PLEASE
hey man, you are a really good youtuber and video creator. really big props to you man.
Super thorough and well done!
Good video!
Converted the 7-10 once on Lane 18 at Lynnwood Lanes in Lynnwood, Warshington, about 47 years ago. I slammed the 7-pin head-on, the pin bounced around the back and bumped the 10-pin over. I definitely put some extra oomph on the ball when delivering it!
I love how deep this is
My brother made it twice throwing about 22 mph at the pin opposite of the ball return and just dead on pinching onto the deck so I can confirm lol
How to make it is to bowl at a place that has good deflection from the back curtains. If you're not at one of those bowling alleys, it doesn't matter what you try.
Did you also study the kickbacks? If it weren't for that design in hardness there would be much less 7-10 conversions including all these non-pocket strikes especially those for two handers that heave the ball down the lane thinking there scores actually count.
You're doing God's work, fantastic breakdown and analysis.
The dozen or so I've been to in Central Florida do not have a helpful back wall (or backstop) that allows for pins to easily bounce off. The back walls on the lanes I've been to are too soft/flexible and absorb too much of the energy of the 7 or 10 pin (whichever was hit) to bounce back onto the lane. I haven't seen anyone pick up a 7-10 split in my 20+ years of bowling at these alleys and the closest I've seen someone get is almost going into the gutter before hitting the 7 pin and it sliding over to the 10. It made the 10 wobble, but that was it. I've both seen and also picked up the 4-10 or 6-7 split more than a few times. I see some comments of people saying they've converted the 7-10 split more than once or even more than a few times. I can believe it based on how this video shows lanes with accommodating back walls. The material used for the back wall and its flexibility or lack of plays a lot into people picking up that split and other difficult splits as well. Having that extra help also helps raise averages in some alleys, but not others. I wish all lanes were equal as it would be nice to see a 7-10 split made in person without having to travel hundreds of miles to find a lane with the right setup.
Shooting at the 7 or 10 can depend what lane you are on. If you have ever seen the pit there are belts feeding the ball into the center of the lane to send it through the ball return. So on the left lane the belt is feeding right, and on the right lane the belt is feeding left. This can play a factor in which pin you should aim for as the movement of the belt should be going with the pin instead of against it. I have no statistical data to back this up, just a theory, but I have converted the 7-10 on numerous occasions using this theory.
So what you are saying is shooting at the pin opposite the ball return makes sense as the belts are moving in the direction you want to help the pin you hit travel.
So in other words, you should aim for the pin furthest away from the ball return?
Did y'all watch the video? Lol he literally gave the stats for the pin on the return side or wall side.. yes go opposite ball return. Left lane aim at the 7, right lane aim at 10
Yes, he made the observation, but never mentioned the belt direction. I was just trying to expand on it.
@ Did "y'all" ever hear of the word "sarcasm"? Or do you just think you're the smartest person on the internet?
What about the pit design? The Brunswick GS series curtain is notorious for the shock absorption although it is still doable. Packy from The House did a video on Brunswick A1 and there had many bounceouts but failed to make it as the pin often flew too far out in front of the other.
it depends on what lane you are on as to what pin you should go for . i’ve converted it 4 times in my life so far all at my home house . once on 18 , once on 16 , once on 15 and once on 9 . on lane 16 and 18 i nailed the 10 . on 9 and 15 i nailed the 7 . this is due to the topography of the lanes and them being ever so slightly slanted one way or the other .
Wow this creator is very cool, it would be super funny if he used to hold a North American Record for Rubik's Cubes
made this spare shooting at the 7 pin, bounced it off the left side wall and it rolled into the 10 pin like andrew andersons conversion in the video. also made it once hooking into the 7 pin, it bounced off the back wall and tapped the 10 pin in the back. both shots were probably about 18.5mph
Picked up the 7-10 using a roto grip hustle RIP back up 1 handed cut the 10 pin on the right side pin guy the wall but the gate kicked out the 7 about 23mhp
Dbl bounce off ball 2 7-10 off of 10 pin 1 off of 7 pin, right hand. Great job on stats!
Interesting video. I’ve made the 7-10 4 times. Righty one hander. All shooting the 10 pin. My 10 pin spares are on average around 20mph at the camera (speed on the screen). But I do tend to put a little more on it for a 7-10. Another 1-2 mph. The last one I made the 10 pin popped back up on the lane, hit the sweep with velocity, and rolled back into the 7 pin. The biggest factor in my opinion is the center you are bowling in. And more specifically some lanes bounce more than others. I would be curious to see what the correlation would be to type of pinsetter/pinspotter.
I've made the 7-10 several times, shooting both at the 7 and the 10.. I think the ball pits // walls at the house you're bowling at are the biggest factor. That being said, I also think it's easier to make 7-10's with a plastic ball because I do believe LESS rotation or at least having the ball not 'biting/driving' and instead 'sliding/knuckling' is more beneficial to getting a lucky bounce. I haven't brought my spare ball with me the past couple years and pretty much every time I leave a 7-10 or throw hard at a 10 pin, the 10 pin tends to just die or be suppressed quickly, it doesn't get the same sort of lively bounce I'm more accustom too when I do use my actual plastic ball. (And yes I'll pipe the ball down there at like ~20mph according to the computer readout).
That being said, this was still an interesting and informative video, I might reconsider how I shoot them based on proximity to ball return and perhaps I'll start bringing my plastic ball again, 7-10s aren't super rare where I bowl, I probably leave one once every 2-3 weeks, but I also don't think I've ever converted one at this current house.
The plastic ball won't slow down as much as a reactive especially if it's in the oil most of the way.
Great info….wow!
Phenomenal video
I made the 7-10 at jensen beach bowl on lane 1. Shot the 7 pin with a 14lb ball at 23mph on the right side and kicked it back on to the deck.
Great video, but to get true numbers you'd have to factor in the success rate of each strategy, meaning taking a much larger sample of all attempts instead of just conversions. This is because some strategies may be used much more often, creating a higher proportion of conversions via that strategy although it might not necessarily be more effective. We would need to see conversions per attempt compared instead of total conversions for each strategy to properly gauge their effectiveness.
I made it twice and both times hit the left side of the 7 with as much spin and speed as I can
I've converted the 7-10 three times, every time it was shooting at the pin opposite of the ball return and at a big angle, trying to get it to hit the corner of the lane since that's where the pins seem to bounce most on AMF pinsetters.
I converted it by just throwing it about 22 mph at the 7 pin with no rotation but I actually aimed for the left side of the 7 pin and it bounced across the back curtain and hit the back of the 10 pin.
Ty I will try this every time I leave one though I hope not to leave too many 😅
Just because more people convert the 7-10 by hitting the pin head on doesn’t necessarily means it’s better, because most of the 7-10 attempts (make or miss) could be hitting the pin head on. Hence, the proportion of makes/attempts may be lower than other tries.
I'm a lefty, have made the 7-10 twice going cross-lane at the 10 pin. One time it bounced across, the 2nd time it bounced off the wall and rolled across. Don't recall if it was the wall side or ball return side, wouldn't matter to me I go at the 10 pin. Good luck!
The first an only 7-10 I've made was on a higher curtain on an A2 pinsetter. I hit the ten pin head on and it was on the opposite side of the ball return. Threw the ball around 20 mph. But all the other times I've shot at it, it appears that hitting the pin on the opposite side of the ball return head on gives you a decent chance at making it. But when bowling on an inverted curtain, hit the ten pine on the far right to get it to bounce off the metal bar and absolutely destroy the seven pin.
Brian Voss is the master of the 7-10 split conversion. I have made it a handful of times because of him. Hit the 10 pin at 45° with speed and lots of forward roll. The pin will pop out and the rest is luck.
Works! Thanks
I've only made it once. I bowl two handed, but grabbed an 8 pound house ball to throw one handed, since you can throw faster one handed. I threw it at the 10 pin, (I'm right handed) hit it straight on so that the ball hit the pin twice, and threw it 26mph
I would like to add that, while more of the 7-10 splits were picked up by hitting the pin dead on, that does not correlate to the percentage of makes... You should find the percentages of each attempt and compare. More players may just aim dead center, giving it more makes because they had more attempts
Of the 15 times I’ve picked it up I’ve shot at the pin on the ball return side all of them.
I haven't watched the video yet, but I want to put this out there. If the conclusion isn't "throw hard and hit a pin," I will be mildly disappointed.
As always the most important part is you need to hit one to get both
If we could see all the charts that would be cool bro
Great video, but I think there are a few factors not addressed. 1. you say using a lighter ball is okay, but how is that determined if you are picking random makes off youtube? How do you know what weight ball the makers are using? 2. It is possible that the amount of lane oil present could affect make %. Since there are fewer lefthanders, there tends to be more oil present on that side. More oil could reduce friction, and therefore save more energy for when the balls hits the pin. But this is also hard to determine from video and small sample size. Very interesting subject to flesh out.
It very much depends on what pinsetter you are bowling on!
The way I picked it up, I was practicing 10 pins, I throw flat handed about 20-21mph, and when I hit it, the pin bounced off the wall and my ball, and was able to fly to the opposite wall, and hit the pin from behind (it then also hit the 4 pin, which was a backwards 4-7-10 pickup i found funny.) only thing is the full rack was standing minus that, and it was the second shot so after I did that, you couldnt prove it
I’ve made the 7-10 split 3 times. Right handed, 10 pin hit, high speed (while maintaining control, so not as fast and hard as you can) with lift/revs ; end over end roll and lastly… Luck! 😊
Can you share the document to your spreadsheet
I once made a 7-10 split by hitting both pins with the ball. I was a kid at the time and rolled a light ball at a very slow speed so it was able to get deflected by the pin. Probably a fluke, I doubt I would have reliably gotten even one pin rolling at that speed.
Step 1: Be Osku Palermaa
Made it one time in practice. About 21 mph, on lane 23, I hit the ten pin on the ball return side. I hit the 10 head on, straight rotation. The 10 pin bounced off of the ball, and directly to the 7 pin. Hope that helps.
They've done studies, you know. 60% of the time, it works every time.
unfortunately this analysis is hampered by the fact that you only analyzed the makes. Because most pro bowlers naturally aim for the middle of the pin when shooting spares, it's likely that the increase in makes that you see when shooting for the middle is because of that. If, for example, you fail when going for the middle 99 times out of a 100 but you shoot it that way 10x as often, then that would mean it is overrepresented by a factor of 10.
Perhaps examining failed 7-10s compared to makes would shine a light on what strategies might work the best, since it makes more sense to shoot slightly inside of middle to get more opportunity for a bounce.
Exactly this. Another example is the chart showing that almost 70% of makes are hit at a "big angle". While I don't know what the population of bowlers for his sample of makes looks like, it's probably dominated by pros, and those pros are going to be shooting across the lane nearly 100% of the time, suggesting that the 3.8% of makes that come from shooting straight on is actually an over-representation (and thus, shooting straight on could be a beneficial strategy, although this is certainly not statistically significant at this sample size).
They don't choose the ten pin over every pin
they choose it over the 7 pin haha
I like the effort, however I don’t find much that’s useful because there’s no attention on failed 7-10 conversions. We don’t know how often people were aiming at the pin opposite the ball return, for example. It’s probably not 50/50 given that it’s a common strategy for making the 7-10. We also have no idea how much speed affects the odds of making it, a ton of higher level bowlers throw around 20 mph at the pins on spares, so it makes sense to see a lot of conversions from the 20 mph range. What would be useful is knowing about how much ball speed affects things, maybe 20 mph gives a 1% chance, and 22 mph gives a 1.5% chance, for example?
Hit it head on and then try for the double bounce, is the way ive made it
What types of bowling are better for making a 7=10 split?
I used to bowl two-handed. Then I turned 7 years old.
Is that when you switched to 3 handed?
It’s 2025 and this dude is still bagging on how someone rolls a bowling ball 🤣
I’ve bowled two perfect games but never made a 7-10 split
What conversion did you use for the thumbnail because it almost looks like the 2020 one at my local center, the guy did it in our big city tournament finals thats covered by the local tv station here
Albert walls jr’s conversion
@Best_of_Bowling Steve walls Jr? That's funny we are going through qualifying for that same tournament these next few weekends XD
As someone who has converted this 3 time the trick is throw it hard and get lucky that's it all 3 were at 10 since I'm right handed also converted the big 4 3 timesthe same way
In 2021 the pba bowler who made the spare hit the 10m
I’ve picked up the 7-10 split 4 times 😊…3 on video
0:36 lol this is totally incorrect
For right handed bowlers it’s way easier to make a 7 pin than a 10 as the ball curves to the left
now when u say speed is it launch speed or speed at the deck?
I almost converted the 7-10 split though
Why are some of the charts very clear while others are blurry? Sure makes it hard to get the info from the chart.
I've only ever seen 1 7-10 made in league bowling and that was by a left-handed bowler shooting the 10 and bouncing it off the wall and into the 7. I never made a 7-10
or the big 5 in 63 years of bowling but have made the 4-6 twice and the big 4 once. Made the 8-10 4 times, always shooting at the left side of the 8 pin and sliding it over
into the 10. I know when an attempt has a chance when the 8 pin slides towards the 10 pin with the bottom of the 8 pin going first. If the top of the 8 pin goes first, it
never quite reaches the 10 pin.
the physical differences between the walls is nothing. they are the same
Half of your slides are out of focus
With low ball speed, you have almost no chance getting it with a kick!
I made the 7-10 once. Too bad I was going for the big-4 at the time... 🙂
What you're not factoring in, is the house itself lol
The house is the biggest factor
Some houses are hoppy and some are dead back there
There are AMF and Brunswick machines. One is easy, one is almost impossible.
I obv commented before the end
nice
Has there been a video recorded 7-10 being made by a woman? I have never seen that done.
Aim for the pin on the opposite side of the ball return channel. I. E. the 10 pin on the right and the 7 on the left.
As I was typing this he said it...
Can you share your data?
Do you solve rubiks cubes
ruclips.net/video/kx8pAzFhEP8/видео.htmlsi=WD3A3uN193yLTJCi
I've made it 6 times, all 10 pin hit first. All around 20 mph. I am right at you data!! Good job.
King is back
