If I tell you the truth, this online game I tried it once and it seemed like a waste of time, but the truth is that it must be recognized that it has many fans and that a lot of people play online, so you have to pay attention to it based on its popularity.
In the AppStore we can find the official game of the page, which is fully compatible with version 3.0 and allows us to fight with our "brute" as if we were doing it on the web, but anywhere thanks to its integration into the iPhone and iPod Touch.
Two applications are available, one free (lite) and one full paid, which has a price of 4 euros in Europe and 5 dollars for the rest, so we lose with the change.
