The designer has done a wonderful job of implementing Dr. Irving Finkle of The British Museum’s ruleset. I do wish it had some sort of graphic representation of the tetrahedral dice and the ability to “roll” your own dice. I have to objection which keep my rating T Four. My biggest objection is THE AI CHEATS! On the highest difficulty level it almost ALWAYS gets exactly what it needs to knock you out, get a second roll, or to score... almost always. It’s even noticeable on difficulty II, but it is much more balanced. My second biggest objection is the amateurish graphic design. While this has no bearing on the game interface or playability, the visual appeal of the original source game Ur, or many other versions available as tabletop editions, just isn’t there. As a graphic designer myself, I look forward playing games that are pleasing to the eye. When I’m playing this it makes me wish I could help bring this best-of-the-ur-apps-so-far to the next level. Ultimately the gameplay is relatively intuitive(except the ~), smooth and enjoyable, which I suppose is most important.
