Introducing the latest version of Game Master. I’ve now added a basic dice roller into the application (check the Window menu) that can handle basic arithmetic, parentheses and dice expressions. No support for exploding dice or dropping the lowest. Unfortunately, to implement the dice roller, I used some new regular expression APIs that were introduced in OS X 10.7. As a result, this version of Game Master will only run on 10.7 or better. For those of you on older versions of OS X, I’ve kept the old version of Game Master available for download (check the side bar).
