Choose a judge who will not paint. Give all players a brush and paper and a glove. Whichever glove you get is the one you have to use. Ask them to each paint a picture. Each person should try to paint the same picture. Here's an example: Paint a house with a door and window, a tree in the yard, a cloud, sun and rainbow, a dog in the yard etc. Let them paint for a set period of time. 5 minutes is plenty. Then have the judge judge the paintings. The judge picks the winner. Make sure everyone sees all the paintings.
