Game description from the publisher:
Little Mouse van Klecks is a world-renowned artist. She has invited her best friends to come over to her studio today to paint with her. Each one of them enthusiastically grabs a paintbrush, paint colors and a canvas and is ready to go! But what's this? The small mouse's artist's palettes are tiny and can hold only three paint colors! How are you going to paint a car this way? Or a house? What about a butterfly?
During each round in Maus van Klecks, the players each secretly pick three colors and dab them on their palettes. The palettes are then compared at the end of the round. For every matching color, the animal artists receive a small tasty tart as their reward. The first player to collect three small cake slices wins.
