Sokker
Although Sokker is entirely free to play, the game also has a premium feature called Plus. The purchase of Plus unlocks additional features that helps managers with their career, it does not however, give any unfair advantage over other users; "They just get more fun from the game - if you are not a subscriber, you have the same chance to achieve your goals in Sokker, as those with Plus." Match kits, Training effects monitoring, graphs, unlimited access to watch all matches, are just few of the features gained when you subscribe to plus.
