A serious game is like a video game that you play on a computer or a phone, but instead of just being for fun, it's used to teach people things or help them understand complex ideas.
For example, let's say you want to learn about science or history. Instead of reading a textbook or listening to lectures, you can play a serious game that takes you through different levels where you have to solve puzzles, complete tasks, or answer questions.
Sometimes, serious games can also be used to help people develop new skills. For example, you can play a game that teaches you how to type, how to cook, or even how to drive a car safely.
Serious games are like regular games, but they have a serious purpose. They can be used to educate and entertain at the same time, and can be a really effective way to learn new things.
