It's random, much like in a casino or in the lottery. While opening more increases the chance you will get the prize, it is not guaranteed.

I am at nearly 2000 boxes opened and never had a single drop. Guildmate opened three, I repeat THREE, and got tobirama.

Yes, I understand the concept of rng, but you gotta admit, feels a wee bit like being shafted.

A friend of mine, pure f2p got tendo inside the boxes. He was lvl 77 or 79 at the time.Personally i have never gotten any ninja and now of only one other player who ever fot a ninja (sasori 100) in our server since it was opened. Then again, one server is not a sample that reflects anything statistics wise.

I really believe its rng. The chance of getting a Ninja though is probably around 0.1% so you would need around 3000 opened boxes to have *most certain probability of getting a ninja.

On an off note, tobirama is probably the weakest of the premium ninja available so i would recommend to avoid spending for him and save your ingots/coupons for tsunade, hashirama or DB hidan.

It's true that this game relies on RNG, but imo there should be some kind of system like seal scrolls, where after a certain number of boxes you get something good.

About this conspiracy, I think I somewhat confirm that I noticed lower level players getting good drops while us getting nothing.

My 2nd character always has better luck, and a friend that joined us only much later in our server has won Tendo twice in Lucky Stars. So ye....there might be something like that coded inside the game to attract lower levels to spend, and also motive the rest of us to spend as well.

I heard lower level players have better luck because oasis wants them to continue playing by giving them false hope.

I personally dont believe this but just saying
