Twenty One

Twenty One/Blackjack powered by Ruby and the Sinatra framework. You play as the participant and the computer plays as the dealer. It is hosted live on Heroku at this link.

I built this from scratch, with the exception of the Sinatra framework. Keep in mind that this app is entirely server-based, so there is no JavaScript or event handling.
