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.

Hanoi5, on October, Oh, dealmadter the entropy-generators do handle “suspiciously repetitive same key typing” – i. Skin and Language Language: Time to get over it If someone feels a specific program is being less than random, there must be ways of checking for flaws and fixing them if found.

No one has proven it cannot. Trinidad, on October, BTW, I was also a math major. Thanks for the reply.

One well liked program – BIg Deal – is now included in Dealmaster. Is there another dealing program that will appease the dealmasher members who want a more less random hand generation – perhaps similar to the current ACBL tournament hands? I realize that physical security is even now more of a danger than cryptanalysis, but we should be able to see dealmasteg “set bits” and the BigBook “page” for every hand generated, on the hand records.

A document describing the process is available by emailing dealmaster at dealmaster. I didn’t look at these hands but the test portion of the report proved that the results were as expected. I don’t know how Big deal is implemented in Deal Master Pro, but it wouldn’t make much sense to implement it without using the method Big deal uses to generate the random numbers.

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.


PrecisionL, on October, It includes a table with the frequencies for all possible hands. That requires a not so standard PC. And then the complaints about the number of voids, singletons and 8-card suits started.

I haven’t been able to obtain an advantage from this yet, but I should be able to in the future.

You can do the same. If the code, for example, uses the standard C library random number generator, daelmaster complaints are likely valid–it is a very poor random number generator intended for quick pto values for testing–no one should use it for serious simulations such as bridge dealing where a good approach to randomness is desirable.

There are a number of other dealing programs out there. The above mentioned data prove its effectiveness.

It would really help if someone knowledgeable in computer science took a look at the underlying code. The data is accumulated.

DM Pro uses a unique deal generation process. Now, any bridge hand generator that doesn’t do the BigBook method of generating hands now is being lazy and by lazy, I mean not reprogramming it.

Dealmasteer the players still noticed a difference between computer hands and hand shuffled hands. All platforms have something sane for generating entropy and cryptographically-secure random numbers for seeds and such. I don’t have hard numbers but I am convinced there is a correlation here. To give just one example, I’ve noticed that there appear deslmaster a lot of series of 5 or 6 hands in which one player picks up the same spot-card.


Most shuffle dealmsster twice. The timing and location of the mouse clicks provide the randomness. 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 delamaster. After 90 days and 60 deals and hands, most players are not convinced that this program approaches statistical norms. It’s random number generator is mathematically more robust than the base one in Dealmaster, but no in a way that anyone would notice even if they played every day.

Generate a Hand Record

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. Remember – most peoples hand shuffling does not give random results.

It did about 22 before it blocked not peo entropyand after that it took about 10, 15 seconds of playing around to get another set. That ended the controversy. Given that the number of bridge deals is a little less than 2 96one would need a 96 bit Mersenne Twister. 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.
