Pigs are intelligent and can play video games. Researchers tested their gaming skills. The researchers got four pigs to play a simple game at different levels. They moved a joystick with their nose to move a cursor. If they did it, they got a treat. The lead researcher said the pigs could understand what to do.

The pigs spent many days playing the game on three different levels. The higher levels had nicer treats. A scientist said: "The pigs clearly understood the connection between their own behavior, the joystick, and what was happening on the screen." The researchers want to understand how pigs learn and understand.
