How does the Draw Something point system work? Well it's really simple, the game gives you 3 different words to draw, these words are of varying difficulty, from easy, medium to difficult. The easy word is worth 1 coin, whereas the word of medium difficulty gets you 2 coins. The most difficult word will get you the most coins, which is 3
There isn't a countdown timer when you are drawing your picture, so drawing it faster or slower does not make a difference in the number of coins that you get. When you are done drawing, your partner will have to guess what you picture is, there's not timer for your parter either, so guessing the words really quickly won't nab you any bonus points. Similaryly, there won't be a penalty given in you place the wrong letters in the boxes, you can choose to take them out or put them back in as many time as you wish.
If your partner correctly guesses the word, both you and your partner will be awarded the respective amount of coins that you were playing for.
