Game & Watch is a special type of handheld video game that was created a long time ago, before smartphones and tablets existed. It was a small device that you could hold in your hand, like a toy, and it had a screen on it where you could play simple games.
Each Game & Watch device had one or two games that you could play, and they were usually very basic, like catching falling objects or jumping over obstacles. You would use buttons on the device to make your character move, and the game would get faster and harder as you played.
One special thing about Game & Watch devices was that they had a built-in clock and alarm. This meant that you could also use the device as a little watch, which was very useful for people who needed to keep track of time.
Game & Watch devices became very popular and many different versions were made with different games and characters, like Mario and Donkey Kong. They were small, portable, and great for playing on the go or during a break at work or school.
Today, Game & Watch devices are considered collector's items and are quite rare, but they were a fun way to play video games in a simpler time.
