If you're looking for fun games to play with 3 friends at school, here are my top three picks.

First is "Tag Multiplayer" published by Tag Unblocked is a great choice. It's simple and fast. You and your friends can chase each other around, and it's always a good laugh. It's also great because you don't need a lot of space or special equipment-just your phones or computers. You can play it in between classes or during lunch.

Another one is "Among Us." It's a game of teamwork and trust. You and your friends try to figure out who the imposter is while completing tasks around the ship. It's a lot of fun when you can't trust anyone and have to be sneaky.

Lastly, "Rocket League" is a great one and I played it many times. It’s like playing soccer but with cars. You can have a lot of fun trying to score goals together.

These games are perfect for when you have a little free time at school and want to have some fun with just three friends.
