well heres the thing, even if you can read japanese , the spinners go so fast its not like you can really do anything about it. just think of it like a slot machine. from what ive gathered youre making a "wish". the first spinner usually has to be red background, the middle spinner is the most important, thats where the songs/characters are, if you get a red/song, then you usually just need to match another red background for the 3rd and you unlock it. basicly its the biggest PITA unlocking system ever, and ive been playing it since it came out and i still dont have everything unlocked, im prolly at like 80%.
ive found the best method is to just hit the red button as fast as u can, i get more results that way then trying to match stuff
