Hello!

As far as I remember, the free Jonin Medal or Trial Medal is a one-time reward for reaching a level in the game. On the other hand, the 3 Free Trial Jonin Medals that you are talking about were given randomly to players before and it is not a regular reward but a mistake that happened, I might be wrong about the reason why it was given out since it is a long time ago already but to answer your question, you will never get that free trial medals again. Thank you.

but i got it in my old account. so why not again?

How "Old" Is Your Old Account (Exactly) Though, Fang San..?

Hello!

I believe I already answered that question in my first reply. The Free Jonin Medal Trial can only be obtained one time per account as you reach a certain level. And if you are talking about the 3 Free Jonin Medals that you got before, read my reply above again. Thank you.

i think its the very first account i used. probably 2018-2019

I'm Not Sure But During My Time (Playing This Game) In 2017 To 2018 Was When The Staff Did Decide To Give Every Player That Was Present (At The Time) The "Free Jonin Medals" That You Were Talking About Above (That Is As Such Though) Which Was A Result Of A Glitch Or Bug That Was Present At That Time And Was Offered To Us As "Compensation" For Said Issue (That Is As Such Though)..I Think Some Reports At The Time Stated Otherwise Is The Case Though Like Reaching "Level 52" Then You Could Obtain "VIP Silver Medals" Though, Thebossofpassio San..?
