Those numbers are suspicious but you're missing the bigger picture. 847 hands is nowhere near enough sample size to call RNG manipulation. You need at least 10K hands minimum before drawing conclusions about dealer patterns.

That said, I've noticed MyStake tends to run hot and cold streaks more than other crypto sites. Their shuffle algorithm might be legit but the variance swings are definitely more pronounced than what I see elsewhere.

Had a similar experience last month but with their European roulette wheel instead of blackjack. Started tracking after hitting a brutal 18-spin losing streak on red/black bets. Over 340 spins, I documented the wheel hitting green (0) at a 4.7% rate instead of the expected 2.7%.

What really caught my attention was the timing - green hits seemed clustered around higher bet amounts. When I was betting 0.001 BTC, green appeared normal. Bump it up to 0.005 BTC and suddenly green shows up every 15-20 spins. Could be coincidence but the pattern was too consistent to ignore.

The provably fair hash checks out every time, so technically everything is legitimate. But there's definitely something in their RNG seed generation that creates these streaky patterns. Whether it's intentional or just how their algorithm handles entropy, I can't say.

Your dealer 20 frequency is definitely elevated but let me break down the math here. Standard blackjack has dealer 20 probability at roughly 23.8% assuming basic strategy play. Your 31.4% rate represents a +7.6% deviation which falls within 2.1 standard deviations for your sample size.

The real red flag is the clustering pattern you mentioned - dealer matching your 19-20 at 38.4% rate. That should be closer to 28-30% in a fair game. I've been tracking similar patterns across multiple crypto sites and found that 7Bit Casino shows the most consistent dealer distributions, usually within 1.5% of expected frequencies.

MyStake's algorithm might be using a different shuffle methodology or their deck penetration could be affecting card distribution. I'd recommend switching tables every 100 hands and comparing results across different stake levels. If the pattern persists regardless of table or bet size, then you've got legitimate grounds for questioning their RNG implementation.

Also worth noting that their Bitcoin deposits and withdrawals are solid - never had issues there. But the table game algorithms definitely run different than what you'd see at traditional online casinos.

This is all way over my head but I'm curious - how do you actually track these patterns? Are you using some kind of software or just keeping notes manually? I've been playing their slots mostly but want to try blackjack and this kind of analysis seems really useful for bankroll management.

847 hands and you're crying about RNG manipulation? Come on. I've hit worse variance streaks at brick-and-mortar casinos in Vegas. Dealer pulling 20s happens - that's why the house edge exists.

You're probably just on tilt and seeing patterns that aren't there. Track another 2000 hands before making accusations about their system being rigged.

Been running similar analysis on crypto blackjack sites since the Leafs started their playoff push last spring. MyStake definitely has some quirks in their dealer patterns but I wouldn't call it rigged - more like their RNG has personality.

What I found interesting is their dealer bust rate sits consistently at 27.8% which is actually slightly player-favorable compared to the theoretical 28.4%. So while they're hitting 20s more often, they're also busting slightly more than expected. The house edge probably balances out over larger samples.

Try switching to their live dealer tables if the RNG bothers you. The human dealers can't manipulate card distribution and the streaming quality is decent for crypto betting.
