I’ve played a few tower defense games, and they can get really addictive! If you’re looking for something new and challenging, I suggest checking out sites like [popular google doodle games](https://googledoodle-games.com/popular/) , where you’ll find various Google doodle games. While it may not specialize in tower defense, the variety of games can still keep you hooked for a while. The simplicity of these games is refreshing, and they load directly in your browser, so you don’t have to worry about downloads or long setup times.
