Shuffling
The shuffling algorithm used to ensure a truly random deck is very important. We use a sort shuffle using a random number generator that generates 2^32 different values pulled from a 4096 bit entropy pool. This is different than the Knuth shuffle used by some other systems, and it has some advantages.
Here is an example of how the shuffling algorithm works.
We assign a random value to each card, as follows:

Ace clubs = 289384521
2 clubs = 1543421228
3 clubs = 410684245
...
Jack spades = 306557875
Queen spades = 1382797013
King spades = 1886740576

Then we sort the cards by their unique index value. This results in an ordering like this:

Ace clubs = 289384521
Jack spades = 306557875
3 clubs = 410684245
Queen spades = 1382797013
2 clubs = 1543421228
King spades = 1886740576

Our method of shuffling eliminates the problem that a single pass Knuth shuffle has involving the modulo bias. It's possible to mitigate the effects of this by using a multi-pass Knuth shuffle, but there's no reason to do that when you can use a superior algorithm.
Some interesting numbers:

A deck of cards can have 52!(Roughly 8x10^67)permutations. This number can be determined simply fairly easily. The first card dealt can be any one of 52 cards. The second card can be one of any of the remaining 51 cards. At this point there are 51x52 different permutations. The third card can be any of the remaining 50, so to find the number of possible shuffled decks you calculate 52x51x50x49 .. 3x2x1 which results in approximately 8x10^67 different combinations.

Given a true random data source, the initial permutation available using our shuffle method is (2^32)^52. This is roughly 8x10^500. Since we use a 4096 bit entropy pool, this means we are pulling our numbers from any one 2^4096 different possibilities which is significantly larger than the possible number of combinations we use. This means that there are 10^433 different ways that we can generate data to get any given random deck. For comparison, it is 10^382 times as likely that one could randomly choose the same molecule of water from the ocean twice in a row than it is that we would ever generate the same set of values to create a shuffled deck from.

Collusion
Collusion is strictly prohibited. Contrary to common believe, collusion is easier to detect online using tools developed to review play history and suspicious activities over time. All reports of Collusion are investigated fully by management with suspicious players being observed closely and shut down immediately with proof of wrongdoing. Should you suspect players acting together during play, forward the game information to: playersupport@gamecitiescenter.com

Site Security
While connected to the MultiPlayerPoker.net server, privacy of all information exchanged is protected using SSLv3 over TLSv1. This security system uses encrypted algorithms to ensure that your personal information remains private. Along with your name, address, credit card numbers and password, game play information also passes through this encryption to ensure complete privacy of your person and your cards. Our systems are third party certified secure by a Thawte SuperCert. In the past, all browsers exported from the USA could only offer 40 bit ('weak') encryption. The 'Thawte SuperCert allows Non-US browsers to bump up to 128 bit strong encryption when accessing our site. In order to make use of this encryption, you must use Internet Explorer 5.01, Netscape Communicator 4.7 or later browsers.
