# What is a TikTok challenge?

A TikTok challenge is a trend where people film themselves doing the same dance, task or prompt, usually with a shared sound or hashtag, and invite others to try it. Most are harmless fun, but TikTok's rules ban challenges that risk serious injury.

## What a TikTok challenge is

A challenge is a repeatable idea. One person films themselves doing something, others copy it with their own twist, and the copies pile up under the same sound or hashtag until it becomes a trend. TikTok's Safety Center describes online challenges as people recording themselves doing something difficult and sharing it to encourage others to repeat it, and adds that the majority are fun and safe.

On [TikTok](/platform/tiktok), challenges come in a few familiar shapes. Dance challenges set choreography to a song. Prompt challenges ask a question or set a theme, like showing your desk setup or your worst haircut. Skill challenges ask you to cook, draw or lip-sync something in a set way. Many use TikTok's remix tools, so you'll see challenges done as a [duet](/glossary/duet) beside the original, as a [stitch](/glossary/stitch) that answers it, or through an Add Yours prompt.

The word is a little misleading. Most TikTok challenges aren't hard, and nobody wins. The challenge is simply to take part. What matters is that the format is easy to recognize and easy to copy, which is how a good one spreads.

## Where challenges come from

Viral challenges are older than TikTok. One famous example, the Ice Bucket Challenge, spread through Instagram, YouTube, Facebook and morning TV in 2014. [Know Your Meme](https://knowyourmeme.com/memes/ice-bucket-challenge) traces it to a Cold Water Challenge in March 2014 and an early ice bucket video posted to Instagram on June 22, 2014. The format gave nominees 24 hours to film themselves pouring ice water over their heads and nominate others, or donate to charity instead. Know Your Meme reports that the ALS Association said it received more than $31.5 million between July 29 and August 20, 2014, compared with $1.9 million in the same period a year earlier.

TikTok itself points to that challenge as a model of the good kind. In a newsroom post from November 17, 2021, TikTok said the 2014 Ice Bucket Challenge helped raise awareness of ALS, and that the #BlindingLightsChallenge took off on TikTok as a family-bonding craze. Know Your Meme dates the first three-person Blinding Lights dance to March 3, 2020, and says it became popular that same month.

## How a TikTok challenge works

Most challenges travel on two things: a sound and a [hashtag](/glossary/hashtag). The sound makes every entry recognizable within a second. The hashtag gathers them in one place, so tapping it shows you how other people did it. The For You feed does the rest. TikTok's help center lists sounds and hashtags among the content information it uses to pick videos for that feed, alongside what you like, share, comment on and watch in full, which is how a challenge can reach people who don't follow anyone involved. Our entry on the [For You page](/glossary/fyp) explains that feed.

TikTok's tools make joining easy. A duet lets you perform beside the original. A stitch lets you answer a prompt after a short clip of it. Add Yours is a sticker with a prompt: TikTok says these prompts are visible to everyone, anyone can respond with their own post, and you'll get inbox notifications when people respond to yours. TikTok also says it may add an Add Yours button to a post that contains a popular topic, to invite others to join in.

TikTok watches hashtags for trouble, too. Its 2021 newsroom post says it built technology that alerts its safety teams to sudden increases in violating content linked to a hashtag, and expanded it to catch potentially dangerous behavior. Its example was #FoodChallenge, a tag mostly used for recipes, where a spike in rule-breaking videos would prompt the team to look for the cause.

## How to join a TikTok challenge

1. **Find the original**: Tap the challenge's sound or hashtag to see how it started and how others have done it. Read the comments to understand what's being asked.
2. **Check it's safe and kind**: Ask yourself what could go wrong, whether it hurts or embarrasses anyone, and whether it's even real. If you're not sure, skip it.
3. **Pick your format**: Use the same sound for a dance, duet the original if it's meant to be side by side, or stitch it if it's a prompt to answer.
4. **Add your twist**: Do the familiar thing your own way: with your pet, at your job, in your hometown.
5. **Write the caption**: Use the challenge's hashtag so people can find it, and credit the creator who started it if it isn't automatic.
6. **Post and watch the comments**: If people tell you something in your video looks unsafe, take it seriously.

If an entry doesn't get many views, our guide to [why a TikTok isn't getting views](/blog/why-is-my-tiktok-not-getting-views) covers the other usual reasons, from privacy settings to For You feed eligibility. The [TikTok hashtag generator](/tools/tiktok-hashtag-generator) can suggest tags to go with the challenge's own.

- Caption on an entry: "Finally tried the three-person dance with my sisters, we tried our best"
- Prompt challenge: "Show the view from where you work, I'll go first"
- Invitation: "Stitch this with your version and tag the friend who'd do it better"
- Comment: "The dog doing the challenge is the only entry I need"
- Brand post: "Our team took on the desk setup challenge, judge us gently"

## TikTok's safety guidance on dangerous challenges

A small share of challenges are dangerous, and TikTok's rules are clear about them. Its Community Guidelines say it doesn't allow content that shows or promotes dangerous activities or challenges. It removes content showing activities likely to be imitated that could cause significant physical harm, which it defines as injuries that usually need medical treatment, such as broken bones, serious burns, poisoning, concussion or choking. Content showing activities that could cause moderate harm is kept out of the For You feed, restricted to users 18 and older, and may carry a warning label.

For anyone deciding whether to join, TikTok's Safety Center offers a four-step routine.

1. Stop: pause for a moment before you react
2. Think: is it safe, is it harmful, is it real?
3. Decide: if it's risky or you're not sure, don't do it
4. Act: report harmful challenges or hoaxes, and don't share them

The Safety Center adds questions worth asking. Did the person in the video have special training, or did they just get lucky? Would a prank embarrass or upset someone, or damage property? Is the scary warning you've seen even true? TikTok says some challenges are hoaxes, lies planted to spread fear, and that when it investigates reports of a dangerous trend it sometimes finds no evidence of one at all.

Its most counterintuitive advice is about warnings. TikTok says making videos to warn people about a harmful challenge often makes it more popular, or spreads instructions by accident, and that sharing warnings about hoaxes makes them seem more credible. So if you see a warning, don't pass it on. Report the content instead: in the app, tap the Share button or press and hold the post, tap Report, choose a reason and tap Submit. If someone is in immediate danger, TikTok says to contact law enforcement.

## What TikTok's research found

For its 2021 project, TikTok surveyed more than 10,000 teens, parents and teachers in 10 countries and commissioned an independent safeguarding agency to write up the findings. When teens described a recent challenge they'd seen, 48 percent called it safe, 32 percent said it carried some risk but was still safe, 14 percent called it risky and dangerous, and 3 percent very dangerous. Just 0.3 percent said they had taken part in one they considered very dangerous.

- 48%: of teens called a recent challenge they'd seen safe
- 0.3%: had taken part in one they saw as very dangerous
- 31%: of teens exposed to self-harm hoaxes reported a negative impact
- 46%: of teens wanted better information on risks

The hoax findings were starker. TikTok reported that 31 percent of teens exposed to self-harm hoaxes felt a negative impact, and 46 percent of teens said they wanted good information on risks and on what counts as too far. In response, TikTok said it would start removing alarmist warnings about self-harm hoaxes while still allowing posts that calm panic and correct the record.

## For parents and brands

TikTok's advice to parents is to talk rather than forbid. Its Safety Center notes that most teens have seen challenges and many have taken part, so saying every challenge is dangerous won't ring true. It suggests asking what appealed about a particular challenge, helping teens spot risks and consequences, giving clear reasons when you think one is unsafe, and looking for safer ways to meet the same need, whether that's doing something with friends, being creative or making people laugh.

Brands that start or join challenges take on the same responsibility at a bigger scale. Keep the task safe for the youngest person who might copy it, make it easy to do at home, and avoid anything that depends on pranking a stranger. If you pay creators to take part, their posts are ads, so the disclosure rules covered in our [sponsored post](/glossary/sponsored-post) entry apply. And a challenge works best as one part of a plan for [short-form video](/glossary/short-form-video), not a one-off stunt.

## Questions

### Are TikTok challenges safe?

Most are. TikTok's Safety Center says the majority are fun and safe, but some promote harmful behavior, and TikTok's rules ban challenges that risk significant physical harm.

### How do I find TikTok challenges?

Tap the sound or hashtag on a challenge video to see the original and other entries. Challenges also show up in your For You feed as they spread.

### Do you have to be nominated to do a challenge?

No. Some challenges, like the Ice Bucket Challenge, used nominations, but most TikTok challenges are open to anyone who sees them.

### What should I do if I see a dangerous challenge?

Don't do it and don't share it, even as a warning. Report it from the Share button or by pressing and holding the post, then tapping Report.

### Why does TikTok remove challenge warnings?

TikTok says warnings about hoaxes can make them seem real and spread them further, so it removes alarmist warnings about self-harm hoaxes while allowing posts that calm panic.

### Can brands start a TikTok challenge?

Yes. Keep it safe and easy to copy, and if creators are paid to take part, make sure their posts are disclosed as ads.
