The Play65™ random dice generator

How can I be sure the dice throws at Play65™ are 100% random?

We use the random number generator described here or in more detail here. You are also welcome to click here for an article about backgammon.

This random number generator was developed in Keio University, Yokohama, Japan. Please note that it is also utilized by IBM. We tested our system by running millions of rounds and examining the results. We also periodically test the system to ensure its integrity. This generator has a very high quality random-number output.

Note that all the game history is saved on your hard drive which includes the dice rolls - we welcome players to analyze these rolls and check their integrity.

Also, please consider the following:

1/6

1/36

1/216

1/1296

…

1/279,936

Since there are millions of dice rolls a day, this will happen from time to time.

Each game has about 30-40 throws in average, your opponent should have about four doubles - probably, two of them consecutive. Having your opponent throw three straight doubles should also occur once every six games or so.

In addition: the chance of having a 6-6 is 1/36 and the chance of having two 6-6’s in a row is 1/1296. This means it could also happen once every 40 games.

These types of throws seem odd but they are statistically expected. Seeing these things proves the dice generator is working properly.

In conclusion, we earn only from the commissions reduced from the winning prizes. Therefore, we really do not mind which player wins, and we never discriminate, nor do we favor any player, group or nationality by dice or any other feature.
