Just got destroyed by 'provably fair' games - are they actually rigged?

[ZestyNoodle]

Lost 0.3 BTC in a single night playing Limbo and Crash at a random casino. Their games are supposedly "provably fair" but my experience was anything but. Lost 18 crash games in a row, all crashing below 1.5x when I was only going for 2x. What are the odds?? Has anyone actually verified these games? Starting to think the whole "provably fair" thing is just a marketing gimmick.

The math is actually legit - you can verify the fairness by checking the server seed against your client seed. But that doesn't mean the odds aren't heavily in the house's favor. These games are designed to make you lose over time.

18 losses in a row at 50% odds is like 1 in 262,144... but with a house edge it's not exactly 50/50. Still pretty unlikely though.

I actually analyzed this. The probability of losing 18 crash bets in a row with a 2x target is approximately 1 in 41,000. Extremely unlikely but not impossible. But here's the thing - thousands of people play these games every day, so eventually someone (in this case you) experiences this terrible luck. It's called survivorship bias.

I get the math, but it still feels off. Anyone else had similar experiences? Is there a way to actually audit these games beyond just taking their word for it?

I've been gambling with crypto since 2016 and here's what I've learned: stick to casinos with real game providers like Evolution, Pragmatic, etc. The in-house "provably fair" games at some places have been caught with modified odds before. For what it's worth, I've had better experiences at TG Casino - their games seem actually fair based on long-term play

Dev here who's worked on blockchain gambling. The provably fair algorithm is legitimate when implemented correctly. The issue is there's nothing stopping a dishonest casino from using different code for "big" players or during certain time periods. Your losing streak is statistically possible, but I'd be wary of casinos that only run their own proprietary games.
