There's two variants to chinese poker, it's pretty simple to get.
I play like normal poker rules
Suits from lowest to highest in chinese way: diamonds, clubs, hearts, spades
Cards from Lowest to highest. 3-4-5-6-7-8-9-10-J-Q-K-A-2
5 card hands from lowest to highest:straights, flushes, fullhouse, four-of-a-kind+anotherCard, straight-flush
The lowest card in the game is 3d (3 of diamonds). highest card is 2s (2 of spades).
You can play single cards, doubles, triples and 5 card hands, there is no four card hand.
You deal 13 cards to each player, preferably to have 4 players, and deal the deck, 13 each. The person with the 3d starts the game, he can play this card as a single, double, triple, or 5 card hand, it doesn't matter, it's just that this person starts off the game.
e.g. a fullhouse. 3d, 3c, 3s, 5d, 5h
If you are playing single card hands, you must play singles until everyone has passed, and the last person to put a card down has control, then this person can play any amount of card down, be it double triple or 5 card hand.
If you can't put anything higher than the last card you pass, this can also be strategy, passing and letting other people play their higher cards first.
The idea of the game is to have no cards left.
================================================== ==
Although, there is another variation of this game (generally called chinese poker) where you have your 13 cards and you need to make your 3 best hands this way
Where the _ means 1 card.
_ _ _ = lowest hand / left over cards.
_ _ _ _ _ = Second highest/biggest hand
_ _ _ _ _ = Your highest/biggest hand.
5 card hands are always bigger than any other hand. Also the difference between this game is that now the 2 is the lowest card and the ace is highest.
but say you had a pair in the second highest hand, but a triple for the 3 card lowest hand, this is not possible because it can beat your higher hand.
The highest possible hand your cards can make weather it's only a pair of 6s, it needs to be in the highest hand and then you sort out your left over cards for the other two hands.
Hope that can clear up some things, which variation did you want to learn?
