Build a Website

I would like a simple rails app that allows for a queue of users to be able to play tic tac toe games in a mysql database. The users should be able to play multiple games and play in REAL-TIME. The game view doesn't have to be anything really special (typical tic tac to grid) and the user authentication needs to be done with devise (so very simple command there - rails g devise install). So, login, have a simple profile where you can put a user profile picture as your X or O and play a game in realtime. At the end of the game it says if you won or lost and redirects you to your profile where you can again click play game. This must be done through MySQL keeping track of users, games and state. I would also like the code to be well documented. The main concerns are using realtime and having users play in realtime with rails and the database sending realtime notifications to the clients on an update. The user should also be able to play more than one game at a time and see their games going on their profile page.
