This page described the benefits of registering with the online clubhouse. However, I have not been interested in playing that way, so most of this UI page is poorly worded Google Translate guesses.

You can apparently be online as a guest or "initial" member. As an initial member you get 1500 points per day to play with. There is also some benefit to logging in on 2 consecutive days in the month. Without playing online, I can't tell how the 100 points accrue.

Or you can join for free as a "registered" member, for additional daily points and a similar extra 50 points somehow.

There is a ranking system for registered members, with titles based on your rank.

Near the bottom are two links, the one on the left for registering online, and the one on the right for signing in.

Your points are integrated online according to the formula at the bottom.

And there is another of those mysterious "2 consecutive days in a month" references.

The arrow at the bottom left will return you to the Start Page.
