Office party multiplayer games you can waste your time on

I made thread here: https://news.ycombinator.com/item?id=26199677 and got some ideas, but I thought I will revamp my thread again and share it with you.

The Kubernetes idea was cool, but Im not sure if work-related themes would be fun during off the job time hehe.

We organize remote office parties from time to time and I thought about playing some multiplayer games with our team. I know classic chess, board games or playing cards are cool, but I was curious if other type of games exist, so they could fulfill our needs.

I suggested some requirements:

-free

-easily accessible and configurable

-no registration if possible

-fun!

So here's the list I made for you all guys if you need:
