Why Does My Yo-Yo String Keep Twisting and Tangling? How to Fix String Tension

It can be frustrating when you're trying to learn a new yo-yo trick and your string keeps twisting, tangling, or getting in the way. If this keeps happening to you, don't worry, it's a normal part of yo-yoing, and it's usually easy to fix.

I'm Gentry Stein, a 2× World Yo-Yo Champion, and I've experienced this at every level of yo-yoing, from learning my first beginner tricks to competing on the world stage.

In this guide, I'll show you why your yo-yo string keeps twisting and tangling, how to tell what's happening to your string, and the easiest ways to fix it. We'll start with simple solutions anyone can use before covering the techniques advanced players use to manage their string while they play.

Why Does My Yo-Yo String Keep Twisting and Tangling?

If you look closely at your yo-yo string, you'll notice that it isn't made from one solid piece of material. Instead, it's made from multiple smaller strands twisted together to create one string.

As you play, those strands can twist tighter together or begin to untwist and become looser. When this happens, your string may start twisting around itself, bunching up, or tangling. In the yo-yo community, this is sometimes referred to as “spaghetti string.”

This is caused by changes in string tension, and it's a normal part of yo-yoing. For most right-handed beginners, the string tends to become too tight, while for left-handed beginners, it tends to become too loose. However, either problem can happen to both right- and left-handed players.

What Is Yo-Yo String Tension?

Yo-yo string tension is the amount of twist in your string compared with its neutral state. As you play, your string can become twisted tighter or untwist and become looser.

There are three basic string tension states:

1. Neutral: The string is close to its natural resting state and hangs without trying to twist around itself. This is the ideal tension you're aiming for.
2. Too tight: The string has more twist than its neutral state and if it gets too tight it may begin twisting, coiling, or bunching around itself when it goes slack.
3. Too loose: The string has untwisted too far in the opposite direction. If it becomes extremely loose, you may notice the individual strands beginning to open or separate.

Whether your string becomes tighter or looser depends on how the yo-yo and string move as you play. Next, let's look at why those changes happen.

Why Does Yo-Yo String Tension Change?

Your string tension is constantly changing as you play. Throwing the yo-yo and performing tricks can add or remove twist from the string. Sometimes these changes happen little by little, while other times your tension can change quickly, for example, if you miss a trick, the yo-yo spins out, or its direction changes.

For most players using standard yo-yo string, normal right-handed play tends to tighten the string over time, while normal left-handed play tends to loosen it. This is only a general tendency, though. Tricks, missed throws, spin outs, and changes in rotation can move the tension in either direction.

While almost everything you do with a yo-yo can affect string tension, some things change it much faster than others. Common examples include:

• Missing a trick or having the yo-yo spin out: The unexpected movement or change in direction can quickly tighten or loosen the string.
• DNA, Helix, UFO, and similar rotational tricks: These tricks can add or remove twist quickly depending on the direction they're performed.
• Lots of movement during tricks: Almost every trick changes your string tension a little. The more the yo-yo and string move, twist, and change direction, the faster that tension can build up.

This becomes more complex as you progress into advanced and unresponsive yo-yo play, but you don't need to understand every possible change in rotation to manage your string tension. The important thing is learning how to recognize when your string has moved away from neutral.

How Does String Tension Affect Your Yo-Yo?

Incorrect string tension doesn't just make your string twist or tangle. It can also change how your yo-yo performs and make tricks much harder to do.

With a responsive yo-yo, like the Vyral, string tension can affect both how well the yo-yo spins and how easily it returns to your hand. If the string is too tight, the yo-yo can become overly responsive, snag, or come back unexpectedly while you're performing a trick or become more difficult to wind. It may also lose spin more quickly, and if the tension becomes extremely tight, the yo-yo may have trouble sleeping at all. If the string is too loose, the yo-yo can become less responsive and may not return when you expect it to.

If your yo-yo still won't return after correcting the string tension, see why your yo-yo won't come back and how to fix it.

Bad tension can also make even simple beginner tricks like Rock the Baby or Elevator much harder because the string may twist, bunch up, or get in the way instead of staying straight and predictable.

With an unresponsive yo-yo, like the DNA, having either too much or too little string tension can interfere with your tricks too. Binds may become less consistent, while slack and whip tricks can become especially difficult because the string may twist instead of forming the clean loops you need.

If your unresponsive yo-yo is coming back unexpectedly even after correcting the string tension, check out why your unresponsive yo-yo is responsive for other common causes and fixes.

And if you're not sure which type of yo-yo you have, check out my guide to responsive and unresponsive yo-yos to learn more about the difference and how each type works.

String tension is especially important for tricks like the DNA, which can change string tension very fast. This applies whether you're learning the DNA on a responsive yo-yo or doing the DNA on an unresponsive yo-yo. If your tension gets too far away from neutral, continuing the trick can become extremely difficult until you readjust the string tension.

Incorrect tension can also make your string more likely to twist, tangle, snag, or eventually form knots. In extreme cases, if the string becomes far too loose and begins opening up, the yo-yo can even come off the string.

No matter which type of yo-yo you're using, learning to recognize and manage string tension will make your tricks easier and help prevent many of the string problems we've covered.

How to Fix Yo-Yo String Tension for Beginners

Once you notice that your string tension is too tight or too loose, there are a few easy ways to fix it. If you're brand new to yo-yoing, start with the first method. It doesn't require learning any tricks and only takes a few seconds.

Option 1) Let the String Untwist Naturally 

The easiest way for a beginner to fix string tension is to let the string untwist while gently sliding your fingers down the string to help it.

1. Let the yo-yo hang at the bottom of the string.
2. Take the loop off your finger.
3. Allow the string to hang freely and rotate on its own.
4. Gently pinch the string near the top and slide your fingers down toward the yo-yo, allowing the string to rotate and settle as you go.
5. Put the loop back on your finger and check the tension again.

This is a simple way to bring your string closer to neutral tension, and it works on any yo-yo. If you're brand new to yo-yoing, you can also watch my beginner guide on how to set up your yo-yo, including the string, winding, and basic string tension.

Then, keep reading below to learn more ways to manage your string tension as you play.

Option 2) Use the Sidewinder to Adjust String Tension While You Play

Once you're comfortable with basic yo-yo control, the Sidewinder is one of the most useful tricks you can learn for managing string tension without taking the loop off your finger.

The Sidewinder can either tighten or loosen your string depending on which side you perform it on. If your hand is on the right side of the yo-yo, it tightens the string. If your hand is on the left side, it loosens the string.

This makes it easy to make small adjustments as you play. If your string is too tight, use the Sidewinder to loosen it. If it's too loose, grab the yo-yo and twist it in the direction that tightens the string, as shown below, until the tension is closer to neutral. See our Learn to Yo-Yo series for a closer look.

Beginner tip: If you're still not sure whether your string is too tight or too loose, try a Sidewinder and check the tension again. If the problem gets worse instead of better, do the Sidewinder in the opposite direction.

Advanced Ways to Fix and Manage String Tension

As you progress to more advanced tricks, especially with an unresponsive yo-yo, you'll have more ways to manage string tension without stopping. Experienced players often learn to make small tension adjustments while the yo-yo is still spinning or as part of their tricks.

There are several ways to do this, including:

• Mini Sidewinder: A smaller version of the Sidewinder that can be used while the yo-yo is spinning to make quick changes to your string tension.
• Bind + Sidewinder: With an unresponsive yo-yo, you can combine a bind with a Sidewinder motion to adjust the tension as the yo-yo returns to your hand.
• Trapeze tension adjustment: From a Trapeze, you can manipulate a string segment around the spinning yo-yo to adjust tension.
• Split Bottom Mount tension adjustment: From a Split Bottom Mount, you can pull the middle string segment to the side and allow it to rotate around the spinning yo-yo, tightening or loosening the string depending on the direction.

You don't need to learn all of these methods at once. As you become more experienced, you'll start recognizing how your tricks affect your tension and which adjustments work best for the way you play.

Your string tension will constantly change as you play. As you get more experienced, you'll learn to recognize when it only needs a small adjustment and when it needs a bigger correction. Eventually, managing string tension becomes a natural part of playing, rather than something you have to stop and think about.

The Easiest Way to Manage String Tension: DNA String

If you don't want to adjust your string tension as often, another option is DNA String, which is designed with a built-in swivel that allows the string to rotate independently as you play.

As your string tension changes, the swivel allows the string to rotate and release some of the twist that would otherwise build up. This helps keep the string closer to neutral tension without requiring as many manual adjustments.

For beginners, this can make string tension easier to manage while you're still learning techniques like the Sidewinder. For advanced players, it can be especially helpful when practicing difficult tricks and variations, repeating DNAs and fingerspins, or working through longer combinations that can change string tension quickly.

Using DNA String gives you a simple hack for managing one of the most frustrating parts of yo-yoing: constantly stopping to reset your string tension. Instead, you can spend less time fixing your string and more time practicing, landing tricks, and pushing your skills further.

What If Adjusting the String Tension Doesn't Fix It?

If you've adjusted your string tension but the string still twists, tangles, or feels inconsistent, it may simply be time to replace it.

Unlike most parts of your yo-yo, is designed to be replaced regularly. How often you need to change it depends on how much you play. Someone practicing a lot may need a fresh string every few hours or days, while a casual player may be able to use the same string for weeks or even a few months.

Yo-yo string wears out with use, and an old or worn string may not perform as consistently as a fresh one. If your string looks fuzzy, frayed, dirty, or stretched out, feels rough, or continues causing problems even after you've corrected the tension, replace it with a new string.

When it's time for a new string, follow my step by step guide on how to replace yo-yo string. Also check my yo-yo string length guide to make sure your new string is the right length for you.

Twisted, Tangled, or Knotted Yo-Yo String: What's the Difference?

These terms are often used interchangeably, but they aren't exactly the same thing.

• Twisted string: The string tension is too tight or too loose, causing the string to twist, coil, or behave differently.
• Tangled string: Sections of the string have crossed, wrapped, or bunched together. Incorrect string tension can make tangles more likely, but missed tricks can cause them too.
• Knotted string: An actual knot has formed somewhere along the string, often during a missed trick. String can also become tangled or wrapped near the axle or bearing inside the yo-yo.

If the knot is along the string, gently try to loosen and work it apart with your fingers. Avoid pulling hard on the string, which can tighten the knot further. If it's too tight or difficult to remove, replacing the string is usually easier.

If the string is tangled, knotted, or wrapped near the axle or bearing, the best approach depends on your yo-yo. With most modern yo-yos, you can carefully unscrew the yo-yo to access the string, then untangle it or replace it. If your yo-yo doesn't come apart, you'll need to carefully pick or work the string out from around the axle. If you can't remove it without damaging the string, you may need to cut the old string off and replace it.

When putting your yo-yo back together, make sure both halves are screwed together securely, but don't overtighten them. Leaving the yo-yo too loose can cause problems while you play, while overtightening it can damage the axle, threads, or other parts of the yo-yo.

String Problems Happen at Every Level

Twisted strings, tangles, knots, and other string problems are a normal part of yo-yoing at every level. Beginners deal with them, and so do some of the best players in the world.

I've experienced this myself. During one of my World Yo-Yo Contest routines, I got a knot that forced me to switch yo-yos in the middle of my freestyle, and I ultimately missed making the finals. More recently, one of our YoYoChampion-sponsored players also had a string problem during competition that forced a yo-yo switch.

Want to see what happened? Watch my breakdown of one of the worst mistakes you can make in a yo-yo contest: being forced to switch yo-yos during your routine.

These examples weren't necessarily caused by string tension, but they show something I've learned throughout my career: getting better at yo-yoing doesn't mean things stop going wrong. You get better at recognizing what happened, figuring out how to fix it, and knowing what to do when you can't.

Learning how to take care of your yo-yo, maintain your equipment, and solve problems like string tension is all part of that process. Whether you're working on your very first tricks or competing on the World Yo-Yo Contest stage, there is always something new to learn and improve.

I wouldn't be where I am today without the help and guidance I've received from other yo-yo players along the way. From showing me how to fix a yo-yo and teaching me new tricks to sharing advice about competition and performing at the highest level, the yo-yo community has played a huge role in my journey.

So if your string keeps twisting, your yo-yo gets a knot, or a trick just isn't working yet, remember that figuring out what went wrong, knowing how to fix it, and continuing to improve are all part of the process.

Show up. Never give up. Lift others up.

Frequently Asked Questions About Yo-Yo String Tension

Still have questions about yo-yo string tension, twisted or tangled string, and how to fix it? Here are quick answers to some of the most common questions beginners have about managing yo-yo string.

Why does my yo-yo string keep twisting?

Your yo-yo string keeps twisting because string tension naturally changes as you throw the yo-yo and perform tricks. Yo-yo string is made from multiple strands twisted together, and as you play, those strands can twist tighter or begin to untwist and become looser.

When the string becomes too tight, it can start twisting around itself, coiling, bunching up, or tangling when it goes slack. For most right-handed players, normal play tends to gradually tighten the string, while for left-handed players, it tends to loosen it. Tricks, missed throws, spin outs, and changes in rotation can move the tension in either direction.

This is a normal part of yo-yoing and usually doesn't mean anything is wrong with your yo-yo or string. You simply need to adjust the string tension back toward neutral.

Why does my yo-yo string keep getting tangled?

Your yo-yo string usually keeps getting tangled because the string tension has become too tight. When too much twist builds up in the string, it can start twisting around itself, coiling, or bunching together when the string goes slack, making tangles much more likely.

Tangles can also happen when you miss a trick, the yo-yo spins out, or sections of string accidentally cross or wrap around each other, even when your string tension is good.

If your string keeps tangling, check the tension and bring it back toward neutral first. If that doesn't solve the problem and your string is worn, fuzzy, or frayed, it may be time to replace it.

Why does my string tension come back right after I fix it?

String tension comes back because it naturally changes every time you play with your yo-yo. Throwing the yo-yo, performing tricks, missing tricks, and changing the direction or rotation of the yo-yo can all add or remove twist from the string. Tricks like the DNA can change string tension especially quickly.

Even if you bring your string back to neutral tension, it will begin changing again as soon as you start playing, so you'll need to keep adjusting it as you go. Beginners can let the string untwist manually or learn the Sidewinder, while advanced players can use techniques like the Mini Sidewinder, Bind + Sidewinder, Trapeze, and Split Bottom Mount tension adjustments to make corrections while they play.

DNA String is a specialized yo-yo string with built-in swivel technology that helps keep your string closer to neutral tension, so you don't have to keep adjusting it as often while you play.

How often should I adjust my yo-yo string tension?

Your yo-yo string tension is constantly changing as you play, so you don't need to adjust it every time it moves slightly away from neutral. Instead, adjust it when you notice the string becoming too tight or too loose, or when it starts interfering with your tricks or how your yo-yo performs.

It's best to correct the tension before it becomes extreme, since very tight or loose string tension can lead to twisting, tangling, snagging, and other problems. As you gain experience, you'll get better at recognizing when your string needs a small adjustment and when you can simply keep playing.

Why does my yo-yo string get tighter when I throw?

Your yo-yo string gets tighter because each normal throw can add a small amount of twist to the string. With standard yo-yo string, normal right-handed throws tend to gradually tighten the string, while normal left-handed throws tend to loosen it.

However, both right and left handed players can end up with tight string tension. Certain tricks, missed tricks, spin-outs, and changes in the yo-yo's rotation can add twist to the string and make it tighter.

This is a normal part of yo-yoing, and you don't need to fix the tension after every throw. Adjust it when it becomes noticeably too tight or starts interfering with your tricks or how your yo-yo performs.

Why does my yo-yo string get looser when I throw?

Your yo-yo string gets looser when twist is removed from the string as you play. With standard yo-yo string, normal left-handed play tends to gradually loosen the string, while normal right-handed play tends to tighten it.

However, both right- and left-handed players can end up with loose string tension. Certain tricks, missed tricks, spin-outs, and changes in the yo-yo's rotation can remove twist from the string and make it looser.

This is a normal part of yo-yoing, and you don't need to correct every small change in tension. Adjust the string when it becomes noticeably too loose or starts interfering with your tricks or how your yo-yo performs.

Why is my new yo-yo string already twisting?

A new yo-yo string can start twisting almost immediately because string tension begins changing as soon as you start playing. Even though the string is brand new, throwing the yo-yo and performing tricks can add or remove twist from the strands.

For most right-handed players, normal play tends to gradually tighten the string, while for left-handed players, it tends to loosen it. Tricks, missed throws, spin-outs, and changes in rotation can make the tension change even faster.

This is completely normal and doesn't mean your new string is defective or already worn out. If it becomes noticeably too tight or too loose, simply adjust the string tension back toward neutral and continue playing.

Why does my yo-yo string get loose when I'm left-handed?

If you're left-handed, your yo-yo string may gradually get looser because normal left-handed play tends to remove twist from standard yo-yo string. Each time you throw and return the yo-yo, the strands can untwist slightly, causing the string to become looser over time.

This is completely normal and doesn't mean you're doing anything wrong. Right-handed players generally experience the opposite, with normal play tending to tighten the string. However, tricks, missed throws, spin-outs, and changes in rotation can move string tension in either direction for both right- and left-handed players.

If your string becomes too loose, you can hold the yo-yo and twist it to add some twist back into the string, or use a Sidewinder in the direction that tightens it. Adjust it until the string is closer to neutral tension, then keep playing.

Why does my yo-yo string twist when I try slack tricks?

Slack tricks are especially sensitive to string tension because the string needs to open up and move freely through the air. If your string is too tight or too loose, the slack can twist around itself instead of forming a clean, open loop, making the trick much harder to control.

Even small changes in string tension can become much more noticeable during slack tricks, whips, and lacerations than during many other types of tricks. That's why experienced players often check and adjust their string tension when practicing them.

If your slack keeps twisting or isn't opening the way you expect, bring your string closer to neutral tension and try the trick again. Neutral string tension helps the slack open more consistently and move where you want it to.

Can yo-yo string twist or tangle on both responsive and unresponsive yo-yos?

Yes. Yo-yo string can become too tight, too loose, twisted, or tangled on both responsive and unresponsive yo-yos. String tension naturally changes as you play, regardless of which type of yo-yo you're using.

Some of the problems you notice can be different, though. On a responsive yo-yo, incorrect string tension can affect how well the yo-yo sleeps and returns to your hand, cause unexpected snagging, and make beginner tricks harder to perform. On an unresponsive yo-yo, incorrect tension can make binds less consistent and make slack, whip, and other string tricks harder to control.

No matter which type of yo-yo you use, adjusting your string tension when it becomes too tight or too loose can help prevent twisting and tangling and keep your yo-yo performing more consistently.

Should I replace my yo-yo string if it keeps twisting or tangling?

Not necessarily. Twisting is often caused by string tension, and incorrect tension can also make tangles more likely, so try adjusting your string back toward neutral before replacing it. If that fixes the problem and the string is still in good condition, you can keep using it.

However, yo-yo string is designed to wear out and be replaced regularly. If your string keeps twisting or tangling even after you correct the tension, or it looks fuzzy, frayed, dirty, or stretched out, or feels rough, it's probably time for a new one.

How often you need to replace your string depends on how much you play. Someone practicing for hours every day may need to change a string after just a few hours or days, while a casual player may use the same string for weeks or even months.

Is something wrong with my yo-yo if the string keeps twisting and tangling?

Usually, no. Yo-yo string naturally changes tension as you play, so some twisting is a normal part of yo-yoing. If the string becomes too tight, it can start twisting around itself, coiling, or bunching up, which can also make tangles more likely.

Tangles can also happen from missed tricks, spin-outs, or sections of string accidentally crossing or wrapping around each other, so a tangled string doesn't necessarily mean there is something wrong with your yo-yo.

If your string is already tangled, carefully untangle it first, then check your string tension and adjust it back toward neutral if needed. If there's an actual knot, gently try to work it apart rather than pulling on the string, which can make the knot tighter. If the knot is too tight or difficult to remove, replacing the string is usually easier.

Is it normal for yo-yo string to twist?

Yes. It is completely normal for yo-yo string to twist as you play. This happens because your string tension naturally changes as you throw the yo-yo and perform tricks, causing the strands of the string to gradually twist tighter or loosen.

You don't need to keep your string perfectly neutral all the time. Small changes in string tension are normal and usually won't cause problems. You only need to adjust it when the string becomes noticeably too tight or too loose, starts twisting or bunching around itself, or begins interfering with your tricks.

String tension is something every yo-yo player has to manage, from beginners learning their first tricks to world champions. As you improve, you'll get better at recognizing when your string needs an adjustment and fixing it before it becomes a problem.

How do I know if my yo-yo string tension is too tight or too loose?

The easiest way to check your yo-yo string tension is to let the string go slack and watch how it behaves. At neutral tension, the string should hang naturally without trying to twist around itself.

If your string tension is too tight, the string has too much twist and may twist around itself, coil, bunch up, or become more likely to tangle when it goes slack.

If your string tension is too loose, the string has untwisted too far in the opposite direction. You may notice the string looking looser than normal, and if it becomes extremely loose, the individual strands can begin to open or separate.

Your string doesn't need to stay perfectly neutral all the time. Small changes in string tension are normal. Adjust it when it becomes noticeably too tight or too loose, or when it starts interfering with your tricks or how your yo-yo performs.
