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.

Finally, we believe DM Pro can create every possible bridge deal. 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. I’m sure if I was playing FreeDoom in another window, it would have gone faster: The data is accumulated. 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, system uptime, process id, Oh, and the entropy-generators do handle “suspiciously repetitive same key typing” – i.

It includes a table with the frequencies for all possible hands.

Sample Dealmaster Screens and Printouts

In Big deal, the random generation is performed by involving input from the user. That requires a not so standard PC. Thanks for the reply. To give just one example, I’ve noticed dealmastrr there appear quite a lot of series of 5 or 6 hands in which one player picks up the same spot-card. I realize that physical security is even now more of a danger than dealmxster, but we should be able to see the “set bits” and the BigBook “page” for every hand generated, on the hand records.


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

I must admit that there were more wild distributions, but I don’t really care.

Dealmster that the number of bridge deals is a dealmasteg less than 2 96one would need a 96 bit Mersenne Twister. 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.

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. Hanoi5, on October, BTW, I was also a math major. That ended the controversy. Is it any wonder that hand shuffled hands are flatter with fewer singletons voids and long suits than there should be? Every time DM Pro deals are generated for club play, the user is invited to print a statistical summary.

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.

I didn’t look at these hands but the test portion of the report proved that the results were as expected. 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?


Dealmsster data shows no bias toward excessive voids or singletons. Then let all the superstitious people with selective memory about dralmaster and such come out and complain and make fools of themselves before you actually switch.

After a while people accepted the fact that they were now playing ‘really’ random deals yeah yeah, it’s not truely random, I ;rowhile they weren’t in the past. PrecisionL, on October, 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.

proo Most shuffle only twice. The timing and location of the mouse clicks provide the randomness. DM Pro uses a unique deal generation process. After 90 days and 60 deals and hands, most players are not convinced that this program approaches statistical norms.

A document describing the process is available by emailing dealmaster at dealmaster.

In the front end by Kaj Backas, one needs to click a number of times with the mouse. I don’t have hard numbers but I am convinced there is a correlation here.

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.
