I want to know from the people that got epic vault keys, how many times did you log in/close the game app in the course of this vault event?
Not a jab at playing too much, since I’m probably in the top 5% of play time this weekend, but I have my own theories about Gems of War that I want to get more correlation data for.
I have to log out and in anyway to invoke the Ads (Android), and I sometimes get the explore screen-locked bug, so I regularly restart. I got my EVK on my 3rd session (about 1hr each).
I didn’t track number of fights because it’s too depressing
140 gnomes
10 keys
0 epic
This is the last time i waste countless hours searching for the impossible, previous vault weekend i did the same with 2 extra keys. Something needs to be done because this is beyond a joke, stop ignoring everyone and admit you lied about the 10%.
I play about 6 sessions per day of varying lengths throughout the Vault event.
Scratch that, I’m an idiot, didn’t comprehend that the question was for those that got a EVK. ;o(
how long would you say it took you to find the epic vault key after opening the game app?
Session 3:
eee(T)eee(T)eeeeeeeeeeeeeeeeeeeeeee(T)[C]eeeee(T)eeeeeeeeee(T)
ee(T)eeeeeeeeeeeeeeeeeeee(T)eee(G)eeeeeeee(D)ee(T)eeeee
e.g. (e)xplore, (T)reasure gnome found, [K]ey/epi[C] found, etc.
Not sure how long the game has been open… lots of pets, tributes all day long
Interim results - I have split out pre-committed and ad-hoc reports as per suggestion by @covertmuffin123
That number in scientific-format (bottom left red font) is the binomial probability of receiving 4 epic vault keys out of 234, should the individual probability of each key being epic be 10%. There is a 4 parts per 10-million chance of such an outcome, or 1 in 2.74 million. Still a higher chance for RNG to cause this than willing the lottery. 
For those curious:
Google Docs formula =BINOMDIST(4,234,0.1,false)
Excel formula =BINOM.DIST(4,234,0.1,FALSE)
6761/7435 battles per epic key. I knew it was close to .01% 1/10,000. The % per key seemed higher than last time.
I didn’t get an epic key, but I had to restart the game a couple dozen times due to the explore lock up bug. Unless that bug only occurs when using a controller, I’d imagine most people probably restated frequently.
I’ve never put much stock in claims of RNG streakiness, but I guess it’s possible that the random seeding is wonky.
I encountered 51 gnomes, earning 3 vault keys and 0 epic vault keys. (I did get Mist of Scales to 19 stars, though, so that’s something.)
Final stats for the weekend:
2167 battles, 227 Gnomes, 19 Vault keys, 0 Epic Vault keys.
I’m so disappointed in myself for wasting many hours again this weekend after the fiasco of the last one. Fool me once and all that. Never again.
Here’s how the addition of Epic Vault Keys being announced went down:
Employee 1: “I’m writing about the drop rate of the new Epic Vault keys, do you know what the programmers set it to?”
Employee 2: “Yeah, it’s way less than Vault keys.”
Employee 1: “But specifically, you got a number I can put down?”
Employee 2: “What’s the chance for a normal Vault key?”
Employee 1: “No idea… but I just need the chance for an Epic Vault Key, not a regular Vault Key”
Employee 2: “Just uh, say 10%.”
Employee 1: “10% of what?”
Employee 2: “10% of whatever a normal Vault key is. That’ll give players hope.”
Employee 1: “Is 10% accurate though?”
Employee 2: “Could be, we’ll find out after enough players send us data!”
Reported my results last time, so was a foregone conclusion I’d do this time except I didn’t post I would 
5,250 trophies on explore. 50 on casual pvp. Does not include world event or pets that I took on and daily delves, although only did 1, just started most of them etc.
60% explore 12, 35% explore 5. 5% explore 3, 6, 7, 8 or 9.
233 gnomes
9 Pity Keys
20 Vault Keys
1 Epic Vault Key (obtained at 180 gnomes)
Misc
5.4 million gold
310k souls
2 Nysha tokens (
)
20 Anu
119 Cedric Tokens (
) edit 149
1066 gross gems (-50 on Sunday diamonds)
Only 3 pets none mythic out of hourly pets.
No vault keys used.
I’m not bothered about vault keys, just go in on explore the one time each vault weekend.
Never again. 
You can include my 8/1 in pre-committed as I did that in another thread.
Thanks, updated. I thought I saw that somewhere. 
FYI You win the 
award as the only person with >10% epic key rate. 
60 Vault Keys – you’re not including the ones you got mailed to you from gnome tracker, right? Cuz I don’t think those can be epic… not sure though.
Based on the screenshot, the guy has killed 783 gnomes. 60 is really not some kind of outlier in VK drops. That 0 EVK could/should be though.
Excel (Open Office, actually) shows 8 VK from Treasure Gnomes and 18 VK (17 ordinary + 1 Epic) from other gnomes giving a total of 26 VK.
Day 3 (much less as all hope has deserted me) 400 trophies, 206 battles, 32 gnomes, 4 vault keys. 0 epic keys.
3-day total: 5400 trophies, 1635 battles, 158 gnomes, 14 vault keys, 0 epic keys.
And if you want a gnome counter that includes from last event, 236 gnomes, 19 vault keys, 0 epic keys.
I did not track battles in the last event, so if you only want this event numbers, that’s fine.
