The impostor
Everybody sees the same word except one person, who sees nothing. Each player draws one line per turn, without talking about the drawing. At the end there is a debate and a vote on who the impostor was.

The rules
How the drawing works
By turns, each player adds one line to the same drawing, in their colour. The line is sent when you let go and the turn passes straight away: you cannot draw half a word in one sweep.
What is worth doing
If you know the word, you have to draw enough to prove you know it, and little enough not to hand it to the impostor. If you are the impostor, you have to draw something that looks like it belongs.
The vote
Once everybody has drawn their lines there is a vote. You can also vote earlier: if everybody asks for a vote, it stops there. Whoever gets the most votes is the accused: if that was the impostor, everybody but them wins; if not, they win alone. A tie goes to the impostor: if the table cannot agree on one name, it means they fooled everyone, which is exactly what they were trying to do.
