2. Skribbl.io
Skribbl.io is a game where two or more people can draw and guess at the same time. Every player gets a turn to pick a card for the other players. Before going on stage to draw for everyone, the artist gets to choose one of three words. The rest of the group puts their guesses in a chat box, but only the wrong answers can be seen.

In this io game, it helps if no one in your group is a good artist. It's a great feeling to figure out why your friend drew something so bad. Even better is when no one else knows the answer and you look like you can read their minds. It's one of the best multiplayer io games.
