Do Online casinos change the odds

[osule]

I started playing blackjack with 100 dollars using the following betting strategy:
$1 bet, repeat if won
If loss, $1 bet again
If loss, $3 bet
If loss, $6 bet
If loss, $12 bet....and so on and so forth
As you can see, I'd have to lose 7 hands in a row to actually lose any money, otherwise, I would have gained $1. It works and my bank grows to about $250 after a couple hundred rounds. I kept a record of wins, losses, and pushes which were pretty what you'd expect.... win some lose some.
Suddenly, there were barely any wins and mostly 7, 8, 9 loss streaks. ( I put in an extra $100 and kept betting only $1). Mind you, I used the same blackjack chart (that tells you when to hit stand, split, etc.) the entire time.
Do you guys think they changed the odds, considering that if people used this, they could keep winning more? Especially, if you had more capital. For example, you'd have to lose 10 times in a row if you started with $800
I played on Parx.

Nope. Martingale, which you’re essentially playing, will give you numerous small wins building your bank as you’ve described. However, a simple statistical fact is that losing steaks as you’ve described are also statistically common and will wipe out your bank - which destroys your martingale approach. Further, think of the 7th or 8th double (whatever it is) bet wagered to recover your initial $1 bet + frighten8ng

Extremely unlikely that the casino changed anything.
What you're doing is called a Martingale progression. You can't use it or any other betting system to beat a game where you don't have an edge.

you're playing a losing strategy and getting the expected results.

As a general rule online casinos do not cheat players through the gambling games they offer. Either they just let the house edge do its work, or in the fairly rare cases of outright fraudulent operations they just never pay you if they win.
There have been proven exceptions to that rule but your likelihood of encountering rigged software is very low.

Just today had a couple of terrible losing streaks on DraftKings football blackjack. First streak was 14 losing hands in a row, and just a couple of minutes later a 13 hand losing streak. Damn, those free Super Bowl bets are going to cost me an arm and a leg. However, the promotion is positive expected value. Already I'm thru tier 4 and if one makes it to tier 10 you get $50,000 in free sports bets. Ah, the catch is you have to bet $2,000,000 on the football blackjack games to get the top tier.

Here is the proof. When you win it says win. There are 3 more losses on the next page which I didn't post.

I have completed thru Tier 6 in the Super Bowl free bets promotion. I now have 10 free bets totaling a $1,000, and I'm going to bet them all on the Super Bowl. However, I don't have to use them on the Super Bowl. I may go for one more tier. I need $150,000 more in blackjack play to complete Tier 7 and then I will have $4,000 in free bets. I won't go any higher than Tier 7.

Online casinos generally operate using random number generators (RNG) to ensure fairness. While losing streaks can happen, it's unlikely that casinos would change the odds specifically based on individual players or strategies. Variance is a natural part of gambling, and it's important to remember that no strategy guarantees consistent wins. That's why I'm more into betting online on the bet365 platform. That way, I should just be sure about my favorite team.

Random number generators are not meant to guarantee fairness. If an online casino wants to cheat, it can easily do so in a way that is imperceptible to statistical analysis.
A simple example could be the removal of some high cards like aces and tens. In an 8-deck shoe, this would be practically undetectable.
Of course, this is not a topic to discuss publicly.

Why would the reduced frequency of tens and aces be statistically undetectable?

Not that I'm suspicious. My online play has been quite successful.

This is true. It would be very easy for a casino to cheat if it wanted to.

However most of us who hustled bonuses observed little to no serious or even minor cheating over decades of play. So for whatever reason most online casinos do not this to the vast majority of players (There is a possibility they might cheat high-rollers as it is difficult to get data on this). The one time I can remember this happening very obviously was with casino888 who would nakedly cheat bonus hustlers after a cashout. But that was once in 15 years. There were other joints which were rumoured to do this which I didn't play at-but you could avoid them fairly easily with due dilligence.

I suspect there is little point to casino cheating. The games are already rigged in their favour. If you cheat a player more than that they may not come back and lose again, and the casino will make less money.

Any online casino that suspects a player CC can hold all winnings, "subject to cheating." Land casino vs Online casino are so vast in difference. A number of online casinos are domain funded in India. That's all I needed to know...

I hesitated to write about this topic because I knew it would generate some kind of debate. I want to clarify something just in case: I didn't say that online casinos are cheating, regardless of whether it benefits them or not. I said that they could cheat and that it would be difficult to detect. It's true that the games are already designed in their favor, but... let's suppose that the initial house edge with 8 decks is 43.25%. If they simply remove one ace from each shoe, the advantage could increase to 50.39% without making any rule changes. By removing just one ten, the advantage would increase to 49.25%. A basic strategy player could go in confidently thinking that their disadvantage is 43.25% when it's actually higher. But this is just an example. Detecting the exact average of tens or aces when only one is missing would be difficult, although not impossible.
