ShuffleMasters

[PokerEveryDay]

For those who know this machine, does it really shuffle the cards randomly? Almost everytime I'm at a table that uses one, it seems the cards are very clumped. I was told it uses a paddle system to shuffle the cards? If so, this could explain it. What do any of you guys know?

Thanks in advance

Nodody knows or has any opinions on this?

the dinky ones you can buy at walmart absolutely suck. But I think you are talking about the ones built into some tables at casinos. They are obviously better. I don't know what kind of entropy they have but at my local casino the dealer usually gives it a few quick shuffles as well after the machine.

Shufflemaster machine is very effective. Steve Wynn invented his own machine at the Mirage but had to pull it because it had a bad algorithm and could be beaten.

Yes, I'm talking about the ones casino's use that are $12K.

If the card distributions 'appear clumped' compared to a hand shuffle, that probably indicates that the Shufflemasters are giving you a MORE random shuffle than hand shuffling, since in general humans underestimate how much 'clumping' there should be in a random shuffle. This first came to prominence in bridge, I think - when mechanical shuffling came in, 'extreme' card distributions became much more common. It took a while for people to realise that this was because the old shuffling scheme wasn't randomising the cards enough, not that the new one was broken.

I just notice patterns all the time when playing with a shufflemaster. For example; 2 10's hit the flop 4 out of 6, a jack hits the flop 8 out of 10, all low cards, all high cards, etc. like that. Rarely do I notice this with a hand shuffle, but it happens. This is simply an observation. If this is actually "random" then I rather it be clumped instead...LOL

Observe 100,000 times and get back to us.

I don't know what the Vegas shufflers actually do, but a high quality card shuffler should be using a true random number generator, and software Knuth shuffle which would make the shuffle uncrackable. Another bit of effort is required to prevent out of band attacks, but the soft aspect of that is uncrackable.

could you explain compared to what "extreme card distribution" got much more common? I somehow don't get your post.
