A handheld video game is a small electronic device that you can hold in your hands and play video games on. It's like having a mini TV and a controller all in one! Some handheld video games have built-in games that you can play right away, while others let you buy and download new games to play on the device.
To play, you press buttons on the device to move your character around and do different actions, like jumping or shooting. The screen on the handheld video game shows you what's happening in the game, and sometimes there are cool sound effects too.
Handheld video games are often popular with kids and adults who like to play games on the go, like while traveling in a car or waiting at the doctor's office. Some popular handheld video game brands include Nintendo's Game Boy, Sony's PlayStation Portable (PSP), and more recently, mobile devices like smartphones and tablets.
