Most typing games use regular text/quotes. This uses real code snippets in 10 different languages (Java, Python, C++, C, Typescript, Go, C#, HTML, Javascript, & Kotlin). Code snippets have uncommon characters that regular text won't let you practice. You can type out snippets in these languages and see a chart of your words per minute, accuracy, and mistakes so that you can improve over time. It's free to play and fun. I improved quickly using this and no longer look at my keyboard when coding.
