I bought 280+ grey keys an I still need the last number :/ I've been at the last number since 130s... It's so frustrating and I'm out of gp for it... Accepting grey keys all day will pay back after I sell back the last few guns I get
haha i got lucky, yesterday i won alot of gp from a hazard, and then bought like 30 keys, and got one of the last 2 numbers i needed. and there were still 5 left that i got, and i didnt get any from those. But later that day i happened to get a 5 shot case from the roulette wheel, and it contained the last number i needed .
So i used about 160 5 shot cases for it
