A lot or a little?

The parents' guide to what's in this app.

Ease of Play

Game mechanic to steer snake is simple but not entirely accurate. Occasional lagging during gameplay.

Violence

Snakes "explode" (but it's not a gory explosion) and then dissolve into dots that are eaten by the other snakes.

Sex

Some profanity and a sexually explicit username observed during review. No filters on usernames, and the game is played against other random people currently using the app (with no ability to restrict to only friends or play offline) so content is dependent on users.

Language

Some profanity and a sexually explicit username observed during review. No filters on usernames, and the game is played against other random people currently using the app (with no ability to restrict to only friends or play offline) so content is dependent on users.

Consumerism

No in-app purchases, no banner ads. Ads pop up when your snake hits another snake.

Drinking, Drugs & Smoking

What parents need to know

Parents need to know that slither.io is an arcade-style game played against other people who are currently online at the same time. Similar to Agar.io, the main objective is to grow your snake into the biggest of the day by eating light pellets as you avoid other snakes slithering around the screen. If your head touches another's, you explode into dots that other snakes can eat. Players see each other's usernames as well as top scores, and W-Fi or data use is required to play. From the home screen, it's also possible to share scores via social media. Note: Even though there's nothing sexually explicit about the game and there's no chat option, some profanity in usernames and a sexually explicit username were observed during this review.

What's it about?

First, enter a username to gain access to the SLITHER.IO game screen, where you'll see a tiny worm with your username nearby. Short swipes move the snake to "eat" small orbs of light, which causes the snake to grow. Increase speed by double-tapping the screen and holding the snake. If you hit another snake, yours explodes and dissolves into light, which then can be consumed by others. The bigger your snake grows, the more difficult gameplay becomes. Players can see their current length, longest length, and top-ranking players in the upper-right corner of the screen. At the end of the day, the player with the highest score can post a message for all to see.

Is it any good?

This just-for-fun fun arcade game uses a bit of strategy, but lagging, ads, and frustration can put a damper on the fun. It's a bit maze-like, and players navigate the small passageways in between the snakes and figure out how to make it more possible for snakes to bump into you. It's unfortunate that even though there's nothing sexually explicit about the game and there's no chat option, users can (and do) choose profanity and sexually explicit words for usernames. Creating an option for kids to play offline against the app (not real people) or limit play to friends only would make slither.io more kid-friendly. Also, while growing snakes can be tons of fun, it can also get frustrating: Seasoned (and predatory) snakes show up to eat you, and sometimes gameplay slows down and can affect how accurate the controls are, which can end with your snake exploding. That's when it may be time to remind your kid that if the quest to grow the biggest snake becomes more compulsive and less fun, it may be time to close the app for a while and move onto something more substantive.

Talk to your kids about ...

  • Families can talk about why arcade-style games such as this can become so absorbing and about finding balance with screen use. If your kid is getting frustrated by his or her exploding snake or low length score, talk about harmless fun vs. pointless frustration.

  • If you or your kid sees a racy username, use it as an opportunity to discuss safe and appropriate usernames in public forums.

  • Talk about the ads that pop up when your snake "explodes." Are they bothersome? Geared toward kids or adults? Are the ads worth being able to download the app for free?
