just finish a game in "family fun" mode. if you want to boost this, just go to "game length" and choose 5 points. press
right after you click the Draw button and say they got it correct each time. you get more points the faster you guess if you keep time bonus on under gameplay settings, so that should be the quickest way (1 or 2 turns). you don't even have to draw anything. i played "ink limit" mode and it took forever because you play until you run out of ink, and i didn't realize you actually get a good bit of ink. i ended up just drawing big circles over and over until time ran out to use it all up.
