Nice interface. But at the top level Ai's cheating, as others have noted, is blatant, relentless, and infuriating... the worst I've seen. For a while, I kept giving it a chance, but eventually abandoned it. A great backgammon would do away with the bogus "levels" configuration, which of course necessitates dice-roll manipulation and/or AI making deliberate mistakes. One "level" only, with Ai playing the game as best it can, and random number generation at all times, would be a great electronic iteration of this ancient game. I suspect it would be a popular download. Beginners would learn faster, and experienced players be more engaged, playing against a tough - but honest - opponent. Of course this assumes developer actually knows the game. I don't understand why developers are ignoring the number one complaint of backgammon users in nearly every version of this game available. Herd mentality it seems, developers all pursuing a "me too" feature that obviously ends up alienating users. Can we at least have one version of backgammon, for the rest of us, that keeps it real?
