I have the rank (313) and i didnt get the achievement Sensei, what's wrong?

Wait 24 hours or so.

As you can see, i waited 24hours and still dont have the achievement.

achievement works with old rank system. It's not about your ratio ingame rank.

Then what kind of rank?

rank which you can see in your achievemnt card


:o/

every belt has own ranking. when you are close to next belt (for example 1950 qi) dont reach it and stop playing. Your rank will go up ;p

thanks
