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.

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. I suggest that anyone wishing to implement computer generated hands at their club start with a one month control period – where you actually shuffling everything by hand yourself, but tell them they were computer dealmasfer.

Dealmaster Pro for Bridge Players

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’m sure if I was playing FreeDoom in another window, it would have gone faster: BTW, I was also a math major.

I don’t know how Big deal is deakmaster in Deal Master Pro, edalmaster it wouldn’t make much sense to implement it without using the method Big deal uses to generate the random numbers.

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. Yes the players still noticed a difference between computer dealmatser and hand shuffled hands. The timing and location of the mouse clicks provide the randomness.


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 would really help if someone knowledgeable in computer science took a look at the underlying code.

Most shuffle only twice.

Remember – most peoples hand shuffling does not give random results. Have you ever watched your opponents shuffle in team games? PrecisionL, on October, No one has proven it cannot. The above mentioned data prove its effectiveness. And then the complaints about the number of voids, singletons and 8-card suits started.

Skin and Language Language: I don’t have hard numbers but I am convinced there is a correlation here. 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.

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.

Given that the number of bridge deals is a little less than 2 96one would need a 96 bit Mersenne Twister. Delete From Topic The post will be removed from this topic completely. 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. In that sample, DM Pro deals were slightly more accurate than BigDeal, but the difference is not significant.


While most of the hands are random, I’ve also noticed the relatively frequent occurance of dealmasster hands, or rather, series of non-random hands. Finally, we believe DM Pro can create every possible bridge deal. One well liked program – BIg Deal – is now included dealmsster Dealmaster.

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

A document describing the process is available by emailing dealmaster at dealmaster. Every time DM Pro deals are generated for club play, the user is invited to print a statistical summary. In Big deal, the random generation is performed by involving input from the user.

I didn’t look at these hands but the test portion of the report proved that the results were as expected. All platforms have something sane for generating entropy and cryptographically-secure random numbers for seeds and such. Hanoi5, on October, The data is accumulated. I must admit that there were more wild distributions, but I don’t really care. You can do the same. It includes a table with the frequencies for all possible hands.
