Someone summarize Saki -Zengokuhen- for me?

[Joyjason]

Because I have an exam on Friday, and even if I didn't, I really don't want to watch another few hours of

1) Omg, this girl has hax skills *break rules of mahjong*
2) haha lulz there's a weakness
3) Yuri power wins the day!
4) Go to step 1 and endless repeat.

Even if it's still ongoing, I'd really appreciate it if someone can tell me if even the first few episodes follow that pattern...

Thanks
