Chances of wining somthing in crates?

There are no set probabilities. Its a gambling.

dont do it u wont get it

u wont get it dont worry

Like others said, it's all luck, because you don't know what is behind all of those spheres. The spray items and the GP item is the most common, I got 5-6 sprays, 4-5 GP items, a P-90 (7 days), a Dragonov (7 days), and a quick defuse (4 days or something). But never a permanent item. Is it possible that if you buy crates in packs (like 5 for 9k) you get a better chance of winning?

ive spent 200-300 USD on the ak scope crates alone.... still dont have it i guess im proff that its luck

really, i personally know that i probably wont get zp crate items just because im negative.
But, the Gp you get out of them, and the other weapons; the seven day variations are a blast to use.
