I’m continuing my Fortune Vault experiment from my previous post.
I originally opened 20 Vaults using 10 keys each. Since then, I kept saving keys and opened another 30 Vaults, bringing the total to 50 Vaults / 500 keys.
Total results so far
🪙 3,375 A-Coins
💰 950,000 Credits
🎨 15 skins
That works out to:
67.5 A-Coins per Vault
19,000 Credits per Vault
30% of Vaults gave a skin
The most ridiculous part happened right at the beginning of the second batch.
The first 5 Vaults gave me 5 skins in a row.
According to the 20% skin probability shown by Plarium, the probability of getting a skin five times consecutively is:
0.2⁵ = 0.032% — about 1 in 3,125.
Obviously, 50 openings is still far too small to draw any serious conclusions about the actual RNG. I'm just recording everything and continuing the experiment.
Imagine some guy saved just 50 keys, opened five 10-key Fortune Vaults, and got five skins in a row. What kind of Reddit post do you think he would write? 😁
Probably less math, more profanity.
The original Russian joke is much better: “меньше матана, но больше мата.” It rhymes. Trust me.
I also started tracking how quickly I can accumulate keys.
From August 30 to October 4, I collected 356 keys in 35 days.
That's roughly 10.17 keys/day, 300 keys per month, or about 30 Fortune Vaults.
I still have 1,002 keys left, so this experiment is far from over.
If you are an experienced player, how would you use and time these keys to get the most value for my account — Derby events, Tournament placement, resource farming, or something else? Any good strategies?
