Can you draw a ninja? Well, can you kind of draw a ninja?
In Pictomania, a rough sketch can be good enough.

Pictomania is the drawing game with no teams and no waiting. Everyone gets to draw, and everyone gets to guess, all at the same time! No one has time to draw a complex masterpiece. The player who can sketch the essence of a word with a few lines will have more time to figure out the another players' drawings. And more time to laugh at them.
