There are a few options apart from just playing games. You should have noticed the champ award in your profile, that's only enabled for this forum. It's possible to restrict it to this topic only, I'm waiting for some feedback about this. It's not a good idea to show it in all forums, it's a fun extra.

There are also automated reset tools for the highscores (hours, days, months) and you can even set a few things yourself in Your Settings such as receiving arcade PM.

There are a lot of other settings and add-ons, so arcade can change.

Have fun.
