The Dragons, Balls, Characters (Cars), Sticks and Winds have 4 similar cards in the deck. The new "Mini Suit," the Dice Cards, numbered 1-6 also has 4 cards each in the deck. There are New "Special" cards added in. There are cards that are used for the American, Vietnamese, Japanese, Malaysian and Singapore versions of playing mahjong. Flower and Joker cards are numbered from 1-4 or 1-8, in case anyone wants to make new rules corresponding to the numbers.
Instead of using regular dice, use the Dice Cards. You can also use the Dice Cards as a 4th suit, especially if more than 4 players want to play.
All the cards are marked at all the 4 corners, so you can fan them out to the left or to the right. The dimensions are 2.25 inches wide x 4.25 inches tall, so it's narrower but longer than a regular card deck.
All optional cards are marked near the edges to help you choose which cards you want to play with, depending on the mahjong rules the players agree on.
Reminder: To shuffle, divide the cards by the number of players, so each player can shuffle a portion. Then each one parts their cards and distributes to the others. Proceed to shuffle again. Do this a few times.
