I don't mean to be a Partypooper, But I would Like to inform you, that sadly, Those types of Games have a lot of Bots. They Want you too feel Like you're online, But In reality, you aren't. A good way to play actual online ones, is to see if it has a Chat. That way, You know it's real people. Another way could be trying to team, If it has no chat. But I'm 100% Sure, Games like Hole.io, and Slither.io, Are Mainly bots. I would like to say though, That doesn't mean you cant have fun playing those games. Heck, I even go to Paper.IO here and there. Just Remember that they Lied to you, And you're not Online. Okay. That is All. Adios.
