Fibby.io

Fibby.io shows you random images from the web and the game decides if you describe the image truthfully or lie about what you see.
Everyone else interrogates you to find out which.

The goal is to make people think the opposite of whatever you're tasked with.
Make people believe your lies and that you're lying when you're telling the truth.
You can do this by describing the image in a truthful, but unbelievable way.
