What makes .io arena games like slither.io so catchy

These games share a short list of ideas. Seeing them laid out makes it easier to choose, because you'll notice which part you enjoy most.

• You start small. Everyone begins with almost nothing, so a new player can still end up on the scoreboard.
• Growing is the goal. Whether it's a snake, a cell or a patch of land, getting bigger is the clearest sign you're doing well.
• Risk and reward sit side by side. Bigger usually means more danger, so every run is a balance between caution and ambition.
• Rounds are short. You can play for a couple of minutes while the kettle boils, then stop.
• The controls are simple. Most use one finger or the mouse, so there's very little to learn.

Which kind of .io game suits which player

• Snake and worm games suit anyone who likes the exact loop of slither.io, with small differences in looks and extras.
• Cell and eat-the-world games suit players who prefer a calmer pace and enjoy the thrill of swallowing something smaller.
• Territory games suit planners, because the trick is to claim land without leaving a trail that someone can cut.
• Tank and evolution games suit people who like making choices as they grow, such as which upgrade to pick next.

If you're after something to play with a friend on one screen instead, take a look at two-player games for one phone.

Checking connection, chat and adverts in .io arena games

• Does the game need an internet connection to play, and is mine reliable?
• Is there a chat feature or a way for strangers to contact my child?
• What age rating does the App Store or the game's site give it?
• Does it show a lot of adverts, and can I live with them?
• Can I use a nickname that doesn't give away my real name?

First rounds and safe nicknames for slither.io fans

These games are simple to start, but a few habits make them more fun and safer for younger players.

1. Use only the game's own website or the official App Store listing, and leave anything else alone.
2. Pick a nickname that doesn't include a real name, school or town.
3. Stay on the edges of the map for the first minute and learn how the controls feel.
4. Don't chase the biggest player. Take small, safe gains first.
5. Take a break after a few rounds, because quick games make it easy to lose track of time.

Parents and young slither.io players

Because other real people are playing, .io games can include chat, nicknames and adverts that you don't control. Check the age rating on each game's store page, look at the in-game settings, and play a round together first. If the game offers a way to turn chat off, it's worth using it for younger children.

Slip-ups that end a slither.io style run early

• Installing several similar games and switching between them every few minutes.
• Using a nickname that gives away personal information.
• Skipping the age rating and the chat settings.
• Assuming every .io game is available on their device without checking the store page.
• Playing for hours without a break because each round is so short.

Picking your next .io snake, cell or land game

Think about what you love most about slither.io: the snake itself, the growing, the near-misses, or the short rounds. Pick one or two games that keep that part, play a handful of rounds, and keep the one you want to open again. When you fancy something slower, puzzle games for PC or strategy games for PC make a calm change of pace.
