While it's true that sound and a smoother, slower animation would improve the game, it's still a great board game and should not be dismissed. I am very annoyed at all of the 1 star reviews because of this. These are niceties, but don't actually affect gameplay. I also saw a lot of 1 star reviews from confused players who didn't bother to read the rules. Mancala's rules are not obvious, and a copy of them should be included in the future, but that is reduculous to rate it low bc of your laziness. Finally, some reviewers gave it ridiculously low ratings of the computer's skill level. Perhaps they failed to notice the difficulty slider in the settings? While in the normal setting it is highly difficult, it is manageable at the lowest few settings, allowing enormous potential for growth in the player's skill. This game isn't likely to become boring bc the player is too smart for the AI. An option to be player 2 against the CPU player would also be appreciated. All in all, the app has room for small improvements, but is an addicting, quick, and entertaining board game, and is well worth your time, especially since it has local multiplayer.
