The game plays well, looks good, and the options are nice, but the absence of sound in the app really takes away from the experience. Also, increasing difficulty seems to occasionally stack the deck to favor the AI. Across a few dozen games, the AIs have been given two and three round Gins multiple times, over my current 1, while using multiple different rulesets. The games are competitive but one AI will oddly pull a consistent lead almost every game.
