Frequently asked questions about .io games

What are .io games?

.io games are free multiplayer games you play in a web browser. They take their name from the .io web address used by early hits like Agar.io and Slither.io. You join an online arena with real players, start small and grow by outplaying others. Rounds are short and you can jump back in with one click.

Are .io games free to play?

Yes. Every game on unblockedio.games is free to play, with no subscription and no credit card. Games are paid for by ads. Some games sell optional cosmetic items such as skins, but you never need to buy anything to play or win.

Do I need to download anything to play .io games?

No. .io games run directly in your web browser, so there is nothing to download or install and nothing is saved to your device. Open a game and press Play. They work in any modern browser, such as Chrome, Edge, Firefox and Safari.

What are fun .io games to play casually?

For quick, relaxed rounds try Slither.io, where you grow a snake by eating glowing pellets, or Agar.io, where you grow a cell by eating smaller ones. Both are easy to learn and a round takes only a few minutes. Browse the casual and puzzle categories for more laid-back games, or sort by votes on the home page to see what other players like most.

Can I play IO games with friends?

Yes. Many .io games have a party, team or private room mode: one player creates a room and shares a link or code with friends. In games without one, pick the same server region and game mode so you land in the same arena. The multiplayer category is a good place to start.

Do I need an account?

Why does a game open in a new tab?
