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.

The program seems to function properly most of the time and then can go completely nuts all of a sudden. Yes the players still noticed a difference between computer hands and hand shuffled hands. If you’re able to control your typing to the microsecond, you’ll be able to influence the RNG though not dealmasteer, because they also bring in things like “number of free sectors on the disk, system uptime, process id, 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 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.

Bridge with Larry Cohen

I’m sure if I was playing FreeDoom in another window, it would have gone faster: The data shows no bias toward excessive voids or singletons. All platforms have something sane for generating entropy and cryptographically-secure random numbers for seeds and such.

Finally, we believe DM Pro can create every possible bridge deal. 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 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.


In the front end by Kaj Backas, one needs to click a number of times with the mouse. 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. It includes a table with the frequencies for all possible hands. 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.

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. Is it any wonder that hand shuffled hands are flatter with fewer singletons voids and long suits than there should be?

Given that the number of bridge deals is a little less dealmzster 2 96one would need a 96 bit Mersenne Twister. Trinidad, on October, Is there another dealing program that will make appease the club members who want a more random hand generation – perhaps similar to the current ACBL tournament hands? 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. Then let all the superstitious people with selective memory about voids dealmaxter such come out and complain and make fools of themselves before you actually switch.

I don’t have hard numbers but I am convinced there is a correlation here. PrecisionL, on October, 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. The above mentioned data prove dfalmaster effectiveness. 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. Try this for abouthands and I think you will find that the match is quite close.


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

It would really help if someone knowledgeable in computer dealmaste took a look at the underlying code. The data is accumulated. Thanks for the reply. I didn’t dealmastet at these hands but the test portion of the report proved that the results were as expected.

Community Forum Software by IP. 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. There are a number of other dealing programs out there. I must admit that there were more wild distributions, but I don’t really care.

Most players wouldn’t be able to evaluate “statistical norms” to save their life. The timing and location of the mouse clicks dalmaster the randomness. 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.

Generate a Hand Record

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? That ended the controversy. BTW, I was also a math major. One well liked program – BIg Deal – is now included in Dealmaster.
