Here are but a few examples of the many Dealmaster screens and printouts . why the Dealmaster Pro bridge simulator program is ideal for Bridge Players. Dealmaster Pro is so extensive in its capabilities that no serious bridge partnership should be without it and it is a must for teachers. You can restrict the dealing.

Is there another dealing program that will appease the club members who want a more less random hand generation – perhaps similar to the current ACBL tournament hands? If the code, for example, uses the standard C library random number generator, these complaints are likely valid–it is a very poor random number generator intended for quick “randomish” values for testing–no one should use it for serious simulations such as bridge dealing where a good approach to randomness is desirable.

I don’t know how this things work but I remember someone made a deal generator in our federation in the 90’s and the seconds needle from the clock would start the randomness.

One well liked program – BIg Deal – is now included in Dealmaster. DM Pro uses a unique deal generation process.

I realize that physical security is even now more of a danger than cryptanalysis, but we should be able to see the “set bits” and the BigBook “page” for every hand generated, on the hand records.

Looking at some of the next hands where north did not hold the club 5, I’ve also noticed a very high percentage of hands where north holds an approximate club 5, for example the club 3, 4 or 6. A document describing the process is available by emailing dealmaster at dealmaster. True, but my partner is a math major and I am a statistics minor and both of us are suspicious of the non-randomness of the hands so far.

For example, noticing that north has held the club 5 for 4 or more hands in a row, I’ve started to expect north to hold the club 5 again on the next hand. You can do the same.


Time to get over it If someone feels a specific program is being less than random, dealmatser must be ways of checking for flaws and fixing them if found. After 90 days and 60 deals and hands, most players are not ddealmaster that this program approaches statistical norms.

It did about 22 before it blocked not enough entropyand after that it took about 10, 15 seconds of playing around to get another set. It includes a table with the frequencies for all possible hands. That ended the controversy. When four or five thousand deals have been created, there is significant data for an informed judgment re accuracy of the shapes compared to standard expected.

And then the complaints about the number of voids, singletons and 8-card suits started. Delete From Topic The post will be removed from this topic completely. In Big deal, the random generation is performed by involving input from the user. I don’t have hard numbers but I am convinced there is dealmasger correlation here.

In that sample, DM Pro deals were slightly more accurate than BigDeal, but the difference is not significant. Every time DM Pro deals are generated for club play, the user is invited to print a statistical summary. All platforms have something sane for generating entropy and cryptographically-secure random numbers for seeds and such. Then let all the superstitious people with selective memory about voids and such come out and complain and make fools of themselves before you actually switch.

No one has proven it cannot. Is it any wonder that hand shuffled hands are flatter with fewer singletons voids and long suits than there should be?

The timing and location of the mouse clicks provide the randomness. Thanks for the reply. Oh, and the entropy-generators do handle “suspiciously repetitive same key typing” – i. I don’t know how Big deal is implemented in Deal Master Pro, but it wouldn’t sealmaster much sense to implement it without using the method Big deal uses to dealmasfer the random numbers.


Most players wouldn’t be able to evaluate “statistical norms” to save their life.

If you’re able to control your typing to the microsecond, you’ll be able to influence the RNG though not much, because they also bring in things like “number of free sectors on the disk, pgo uptime, process id, It would really help if someone knowledgeable in computer science took a dealmastrr at the underlying code. After a while people accepted the fact that they were now playing ‘really’ random deals yeah yeah, it’s not truely random, I knowwhile they weren’t in the past.

Trinidad, on October, Yes the players still noticed a difference between computer hands and hand shuffled hands. Have you ever watched your opponents shuffle in team games?

Finally, we believe DM Pro can create every possible bridge deal. Hanoi5, on October, To give just one example, I’ve noticed that there appear quite a lot of series of 5 or 6 hands in which one player picks up the same spot-card. I haven’t been able to obtain an advantage from this yet, but I should be able to in the future. The data shows no bias toward excessive voids or singletons.

If the code, on the other hand, uses a good random number generator such as the Mersenne Twister, I suspect we are seeing artifact of selective memories. In the front end by Kaj Backas, one needs to click a number of times with the mouse. Skin and Language Language: PrecisionL, on October, Most shuffle only twice.

Remember – most peoples hand shuffling does not give random results. I’m sure if I was playing FreeDoom in another window, it would have gone faster:
