Crash is a Hash Chain. Round 1 would be the end of the hash chain. Any funny business and it breaks the chain.
The hash you see is the Seed for that round. When you take next round's seed/hash and Sha256 it, you get the round before its Hash/Seed.
So again "There's 0 Machine learning in a Provably Fair System.You should research what Provably Fair is. and learn how it works, You would most likely Benefit from the Knowledge. "
So they have provided everything that is needed to know/check that Crash isnt cheating. As far as predicting the outcome goes, Its rather impossible to know/find/crack what was Sha256 to make this:

Even if you did somehow magically figure out '4067c28bd2e7d67999295fbb70212abd0bcfe987a56117325f3662c00229ea2c' was hashed to create it, you would still need to figure out what was hashed to create that. Keep in mind you would have to do this in the instant between rounds.
