The chance of winning the 3 lines reward of Wondrous Tails is ridiculously low
So, as soon as the patch notes, I tried to find out how to calculate the probability of winning this mini game, and this is what I deduced.
By fulfilling weekly objectives, you can gain up to 9 seals which are placed randomly on a 4 x 4 grid, as seen in the patch notes screenshots.
There appear to be this many pattern possible :
16!/[9! * (16 - 9)!] = 11440
I was able to identify 24 winning pattern.

11440 / 24 = 476
So, after going through the hassle of doing those 9 objectives, you have one chance out of 476 to win the best rewards ?
That's a lot of time for such a little chance.
Feel free to correct me if the calculation is wrong but so far, it seems a really disappointing addition.
