An indie game is a kind of video game that is created by a small team of people, usually independent from big game companies like Nintendo or Sony. It's like when you and your friends make up a game to play together, but instead of just playing it for fun, you actually make it into a real video game that other people can play too!
Because indie games are made by smaller groups of people, they can be really creative and unique. They often have different ideas and styles compared to the big company games that you might see on TV or in stores. It's kind of like when you draw your own pictures or build your own creations with Lego, it's all your own special idea!
These indie games can be played on different devices like computers, consoles (like Xbox or Playstation), or even your phone or tablet. Some of them are even available to play on the internet for free, while others you have to buy to play.
Sometimes, indie games become really popular and lots of people play them. They can become famous just like the movies or toys you might know. Since they are made by smaller teams, it's a big achievement for them to have their game be liked and played by many people.
Overall, indie games are pretty special because they come from the imaginations of smaller groups of creative people, and they bring new and interesting ideas to the world of video games.
