I think there might be something wrong with the dice-throwing algorithms of this game. The dice seem heavily weighted in the computer's favor. I played over 50 times in demo mode and only won four times. The computer frequently reaches the scoring threshold well before the human player, building up an insurmountable lead. When the human reaches the threshold first, the computer frequently reaches on the very next turn. The game keeps stats, so one can see that the computer consistently Farkles on six dice fewer times that the human. The computer seems to get high-scoring combinations on the first roll with ease and regularity while the human would take several rolls to get the minimum.
I think twenty dollars is too much to pay for the stilted graphics and sound, and clunky interface. It doesn't seem to take advantage of Mac OS APIs. It has a first-year Java student look and feel. Despite that, it could be enjoyable if it didn't seem to cheat.
