A cooler version of chess where you can strategize, upgrade weapons and armor, and play against friends!
The learning curve is really easy as everything you need to know can be explained to you through the incredibly useful info button. Strategy is of course crucial in this game and every player picks up their own and makes it work for them. New players will find themselves quickly learning from their mistakes and getting better after each game they play.
You can start games against random players, or you can start custom matches against your friends (as long as you know their code name). The amount of games you can have going at the same time is 40, so wether you want this game to keep you busy for long or short periods of time all you have to do is start as many games as you want.
