Each player takes some paper and a pencil (four are provided). Chose any player to be the first Instructor. All other players are Doodlers for the first round and rotate for later rounds.
The Instructor takes the top card from the Doodle deck and tries to describe as best they can the object on the card using only "technical" terms. The Doodlers follow the directions of the Instructor, trying to recreate the object on their Doodle Sheet. No one can look at another's drawing. Once the Instructor announces the description is complete, each Doodler secretly writes down what they think the object on their sheet is.
Each correct identification is worth one point to the Instructor. Each correct Doodler gets one point. So, if 3 Doodlers guess correctly, they each get one point and the Instructor gets 3 points. The player with the most points at the end is the winner.
