Seriously, I read where we can have a group of 3 tiles of the same number - do they have to be from the same group? (I would call it a suit.)

How in the world do we use dragons? There are only 3, but that doesn't work for a meld either.

Can we get some discussion of what tiles go with what?

The valid melds are as follows:

1) Three identical tiles (such as three #7 circle tiles)
2) Four identical tiles (such as four north winds)
3) Three numbered tiles, same suit, in sequence (such as 5-6-7 of bamboo)
4) Two identical tiles (such as two green dragons -- this meld can only be used as the final meld of a round)

I have proposed a Mahjong variant, called Grandma Jong, that includes more melds.

No mention of that in the rules. I've wasted a month on a game waiting for a final tile for a chow I now can't use

In the western standard rules, you gain an extra tile for a Kong, giving you 15 tiles, but maintaining the <set><set><set><set><pair> requirement for a Mahjong.

I would class this as a)House Rules (probably because it was easier to code) or b) a bug.

The easiest way to deal with it is to take option a) and update the doco. This can also be used to document the absence of the various unusual format special hands, like Unique Wonder, All Pairs, or Knitting.

on a player's turn they have the OPTION of playing ONE or more tiles! How do I have the option of ONLY placing ONE tile? The game (I had four 5 tiles left) I melded a valid set. but my last two tiles were not identical and I had to discard one! Now the board/tiles resetted, The starting pts is 15 which I had on my last meld.
So 1) to win the game, do ALL the NEW tiles in hand have to be played? 2) If so, WHAT TYPE of set should be try to hold in hand when I'm down to six tiles?

In Dragon's Nugget he states a KONG is 4433 (Does this mean TWO IDENTICAL tiles can be placed on SAME LINE with a different TWO IDENTICAL tiles? ALSO, do 4443 = THREE IDENTICAL tiles + ONE tile of SAME SUIT but a LOWER NUMBER tile????

4-4-3-3 = 2 sets of 4 tiles + 2 sets of 3 tiles which add up to using 14 tiles!!! BUT it seems I must try to get a KONG meld since 3-3-3-3-2 also add up to 14 tiles, but can't end the game. WHY!!! And when the board RESETs over, the same sequence set (ex. 4-4-3-3) must be done!! WOW!!
Is this correct?

I had all four wind tiles (north, east, south, west) and could not post them as three tiles or four? how do you use the wind tiles?
