About BETRAYAL io

Game Description

Betrayal.io is basically a browser game where you jump into a crew of 6 to 12 players and try to figure out who’s the impostor messing things up. It plays a lot like Among Us but way simpler to get into since you just need your mouse. Everyone’s running around doing tasks or sneaking around trying not to get caught, and the goal is to either keep the crew safe or be the sneaky betrayer without getting found out. It’s quick matches, so you can jump in and out pretty easily, and playing with friends makes it a lot more fun.

Story Background

The game takes place in a sci-fi setting where a group of space crew members are trying to complete tasks aboard a ship while one or more impostors secretly try to sabotage the mission and eliminate the crew.

Why This Game is Addictive

Honestly, it’s the social part that gets me hooked. Trying to guess who’s lying, calling out people, or being sneaky yourself makes every round different. Plus, the short games mean you can keep playing without feeling stuck, which is great when you only have a little time.

How to Play

Desktop Controls

You just use your mouse to move around and click on tasks or buttons. Super simple, no keyboard needed.

Mobile Controls

On mobile, you tap where you want to go and tap on tasks or buttons too. Pretty much the same as desktop, just with touch instead of clicks.

Pro Tips & Strategies

Don’t rush accusing people right away; watch how they move and what they do.

Stick with someone you kinda trust, but don’t get too comfortable—impostors might use that.

Pay attention during meetings, sometimes what people say or don’t say is the biggest clue.

Try to complete tasks quietly but keep an eye on who’s nearby.

If you’re impostor, blend in by pretending to do tasks and don’t get greedy with kills.
