This was to help me learn how to manipulate the DOM with JavaScript. In the early stages it also helped me learn the HTML Click and Drag API, along with other draggable functionality, though it didn't keep that functionality throughout the development process.
Now, the app is a fully functional "Tower of Hanoi" game that you can try out for yourself here.
You may have noticed that "Final" is in quotes, and for a good reason. As is, the game plays well and performs without any issues. However, in the future there may be new features added such as a game timer, a way to select how many rings to start with, and making it more mobile friendly.
If you would like to, please try out the game. Feel free to leave any suggestions/PRs for improvements, and I'll do my best to address/implement those changes.
