Based on observations, it might be random or there must something else controlling it. There are some games that seem that the outcomes are better when you attend them, while there are others that seem that it is better not to attend (and probably, not to login during that time). So, indications for randomness are there. There may or may not be be a directly relation with attending and outcome. As things appear to be, sometimes I suspect that the game tries to fool you into believing things that are not actually the case.

Logically, attending games should be superior, but this game has showed a lot of weird 'behaviours'. There seems to be a lot of football 'nonsense' in this game.
