Just got one from my 10k scratchcard achievement, and the Subeta Wiki says " There is also a Golden Glory Scratchcard that gets an automatic Jackpot win, but this kind of card only comes from the Achievement, a random event, or from other users who got it that same way." But...

Is the wiki just wrong, or is this a glitch? All my previous ones have been jackpots so it's seemed right so far. Not a huge deal, at the end of the day it's 1.2mil and it's whatever, but definitely felt anticlimactic.

unfortunately the subeta wiki can’t be 100% trusted with the info it gives - lots of time the information found there is anecdotal at best and is added by contributors who may not be 100% correct since it’s a resource that anybody can edit. ;-; the golden glory scratchcard only gives an INCREASED opportunity of a jackpot, not guaranteed. i’ve lost on many myself. i’m so sorry friend ♥️ wishing you better luck on any future scratchcards you might do!
ah that makes sense, I wasn't sure how affiliated/real it is as a site (edit: I got a forum point making this post so the RNG is back on my side apparently lol)

It looks like you already got your answer - the Golden Glory Scratchcard gives you an increased chance at a jackpot, and it is not automatic. The Subeta Wiki is a fansite, and may not have 100% accurate information.
I'm going to close this since there's no bug or glitch here!
