One thing I've noticed, when watching someone guess my drawing, they knew the answer extremely fast... before anything was really drawn. Well if you exit the app while watching the drawing being made and go back, it starts over fresh. I got interrupted watching a drawing that was nearly finished, and when I went back to it, I already knew the answer so was able to type it in really early during the "guess" turn... Might come off as rude, but I did watch the whole drawing the first time...
The boggle thing, well, there's not a ---steaming pile of meadow muffin--- ton of words and many can be guessed quickly without a drawing.
