I started by porting my old Texas Hold’em Odds calculators from Java to Flash (since no one has Java =p). I still wanted to use Java for the back end calculations, so I also had to learn how to write Java Servlets. It’s been a lot of fun. Mostly because I’m a big fat nerd.
After getting a little Flash experience I created a new KenKen application. Check it out and let me know what you think: http://www.ben61a.com/kenken/
