Wow, nice new interface for the new Janryumon 3 - and a few other things added in its GUI.
That said, there is no division between Jukuren and the "lower division" in the public games now - all public games are in one set of rooms, while a league room has been added.
For each hand you win, you gain a treasure chest, but apparently, you will only get the true contents of the treasure chest IF you finish first (or second, I can't tell for sure).
There are possibly a lot more things that I have yet to see though in the new Janryumon 3.
