Very good, but the random generator needs a touch up. Often clicking the Roll button brings back the same numbers. Other than that, it's a good relaxing game. Works well in Linux Mint 18.3
I haven't had any issues on Mint14. It's a very simple and quick dice game that can burn a couple of minutes.
I've tried this game a couple times, and each time, I play once, and the .rc file is written and unless I delete it, thus starting over, it won't open. Interesting, and very annoying, bug.
kind of fun, but plays only in vertical mode; if you switch it to horizontal the text disappears
