8 Suits – eight suited playing cards

8 Suits, as you guessed is a deck of playing cards with an additional 4 suits, the clover, tear, crescent and star for a total of 104 cards plus a number of jokers.

Priced at $12 USD per deck plus $5 per postage ($13 per postage internationally), it is a little steeper than The Fat Pack, at roughly $16 USD including international postage. Unfortunately, I discovered the former after ordering the 8 Suits.

5 Dimension – a 5 suit playing cards

I recently purchased a 5 Dimension (5D) deck of playing cards from Canada for $5 (plus $5 shipping to Australia). Unlike a normal deck, the 5D deck has an extra suit, the star, plus a numeric 1 card (as opposed to an ace), a princess card and jokers, totalling 80 playing cards.

5 Dimension playing cards

The cards are standard bridge size 2.25″ x 3.5″ (the thinner width making it easier to hold more cards), with a card width of 0.3 mm. The card material is of quite good quality, with no ruined corners yet.

So how does an extra suite and more denominations affect the probabilities of standard 5 card poker hands? With reference to Durango Bill’s Poker Probabilities, the probabilities in a 5 suit 13 denomination deck are as follows:

Poker Hand        Number of Combinations     Probability
Royal Flush                         5        .0000006053
Five of a kind                     13        .0000015739
Straight Flush                     45        .0000054480
Four of a kind                  3,900        .0004721614
Flush                           6,385        .0007730129
Full House                     15,600        .0018886455
Straight                       31,200        .0037772909

Total                       8,259,888       1.0000000000

The biggest difference is a Full House is easier to be dealt then a Flush.

Now, how does adding a One and Princess denomination affect the probabilities.

Poker Hand        Number of Combinations     Probability
Royal Flush                         5        .0000002897
Five of a kind                     15        .0000008691
Straight Flush                     55        .0000031867
Four of a kind                  5,250        .0003041822
Flush                          14,955        .0008664849
Full House                     21,000        .0012167290
Straight                       37,440        .0021692540

Total                      17,259,390       1.0000000000

A Full House remains a higher probability, but with a high probability of obtaining a Flush.

Update: October 2009

After over a year of use and into the second deck, I thought I would retract my statement stating ‘The card material is of quite good quality’. These cards damage very easily, the photos speak for themselves.
