The game's mechanics are identical to the original version. This is to say that the objective of each is still to gather four or more animals of the same color to make them disappear and send an attack against your opponent. Or you can try to achieve a high score without playing against anyone.
Because it is integrated in LINE, LINE ZOOKEEPER allows you to play against and compare scores with all of your contacts. It's as easy as checking high scores. Because of it's ease of access, there is a high potential for fun.
LINE ZOOKEEPER is a very enjoyable game with the only downside being that it can become too addictive. Don't be surprised if you find yourself spending more time playing the game than talking with your friends!
