Maybe it's silly, but can someone explain the site to me for a bit 'cause...

Honestly it's not too clear to me O.O

It advertises that you can study while "playing games and earning experience points" but i haven't found the "game" part yet. Sure, you can earn points by doing quizzes but there's no way to do the actual learning and memorizing through games. And there's no Help section or tour of the options so... Can someone clearify?

'cause if i still have to just cram the kanji etc. the old way ( which is fine on it's own) i could better go back to My japanese coach for the games part~
