Trying to rely on genies to win diamonds is not the best decision; you can easily get RNG-screwed. You're better off farming level 1 spire on your other cities each week and level 2 if possible. I've only gotten 5 diamond collections (4 50s and 1 100) in my last 200 collections. P(X<=5) with a sample size of 200 at 8% success is 0.1% or 1 in 1000. Then again, I've never really trusted Inno's odds that much lol
Let's see, I have 5 Genies in one city and with 23 days left I have collected 3,300 diamonds so far not great but HEY that is 3,300 more than I had before in my other city
(and another account) I have 8 Genies and have collected 3,800 diamonds and have 45 days left.
Is that good or bad, more diamonds for no additional money, seems reasonable to me, or am I wrong? Oh and I top the spire most every week.
