Pigs may more intelligent than we thought. They may be able to video games. Researchers at Purdue University in the USA research on pig-gaming skills. The researchers were surprised that their test pigs were able to some games. Researchers got the four pigs, Ebony, Hamlet, Ivory and Omelet, to play a simple game at different levels. They had to a joystick with their snout to make a cursor to a coloured wall. If they successful, they got a tasty treat. Lead author Dr. Candace Croney said: "It's very clear they had some conceptual understanding of what they were asked to do." The research is in a paper in the journal "Frontiers in Psychology".

The research was quite extensive. The pigs many days playing the game. During the last 50 rounds, the pigs the game on three different levels. If they were successful at one level, they to the next level. The higher levels had better treats. A scientist CNN that: "The pigs clearly the connection between their own behavior, the joystick, and what was on the screen." Dr. Croney said it was important to understand how pigs get information, and what they are capable of learning and remembering. She said this would us to learn what pigs of interacting with humans. We could also what pigs of different environments.
