A royal flush is 649739 to 1 and a straight flush is 72193 to 1
Aside from the odd cases like at UB, there is no way a site would rig results. The poker site wins the same amount in rake whatever the outcome so their objective is always to get more players plating and lose less. Nothing else will make them more money. Rigging results would destroy their reputation and thus lose players. It is a sure fire way to lose business and make less profit.
That's not to say players are not always looking for an edge and will try sophisticated forms of collusion etc.
The odds of the lesser hand winning, even for something trivial like a gutshot straight draw are as high as 17% over two cards - you're playing a lot more hands online than you would live, these things happen.Although regulated (or I hope it is) I will say this about pkr.com.
1.There appears to be many more times the river or turn will make the lesser hand win.
Again, these things aren't impossible and these are gripes everyone has with the game. Because you're playing a lot more hands you'll see a lot more of this happen. As for the odds of a royal flush, over five cards your odds of seeing one are something like ~1/600,000, or ~1/60,000 for a straight flush (my maths may be off somewhat). However in hold'em, seven cards are dealt. Couple that with the fact you're playing a lot more hands than you would in a live game, and you can add to the 'weird' things.2. I have had 7 str8 flushes and one royal flush and seen several others. They do say you might go all your life without seeing one.
It just seems that the weirdest results come out sometime. The other week there was three of us left. We had AA, KK, QQ and the flop was AKQ. Everybody was allin. The river was another Q. I don;t even want to try and calculate the odds of that happening (I had KK btw and thought I was onto a winner)
Hmmm...bit suspect, just had 44, 22, 44, 33 hole cards in a row, what are the odds of that
If you said specifically " in the next four hands I will be dealt 44 then 22 then 44 then 33 " then it is 2385443281/1. A specific pair is 221/1 so 221^4.
If you said " I will be dealt 4 pairs in the next 4 hands " then it is I think 17^4 = 83521/1.
Truth is you didn't do either of those things, you observed it after it had happened. So it isn't really /1, people like yourself are always looking for 'anomalies' and then report them as if they are something spectacular. Truth is they are nothing more than random chance.
The classic case is being dealt AA twice = 48841/1. Your only ever really looking for this is after you've been dealt aces the first time so it's more like 221/1.
Never thought about it as an after the fact thing, glad you pointed that out as it can't be a xxxxx/1 occurance.
However on the subject of AA, I think I see that pair come up at least 4 out of every 5 games.
