Cranium Cariboo is a game for young children (Ages 3 - 6) to help them learn letters, numbers/counting, colors, and shapes.Players take turns drawing a card and opening one of the treasure hunt doors that has a trait corresponding to the card (color, number of objects, etc.). Once the door is opened, players look for a ball. If they find one, they drop it in the 'tide pool'. Once all six balls are found, the treasure chest opens and everyone wins (there are scoring rules, if a cooperative win is not desirable). - BoardGameGeek
