best crypto casino if you want to check game fairness with actual math

so, i get why everyone hypes provably fair stuff, especially with crypto. you want to see the numbers, verify seeds, trust your own math instead of just taking the site's word. makes sense, at least on the surface. but then i start thinking how much can you actually verify beyond basic hashes and blockchains? even roulette, my go-to, there's always some black box you just have to trust at the end. anyone actually done the deep dive or are we all just pretending the math is enough? where do you draw the line for “fair”?
