The Basic Rules and the Payoff Scheme section of the official Zung Jung rules, in addition to the patterns themselves, mold the game into what it is. Without these rules, the game wouldn’t differ much from other variants. Most are easy to follow and obvious in their impact, but a few are worth commenting on in greater detail. In this article, we’ll take a look at the rules which most shape the game.

Basic Rule 4 – The Additive Rule

In brief, the Additive Rule states that if your hand qualifies for multiple patterns, you can count all the patterns when determining your hand’s overall score. As long as the patterns don’t share the same series (the second number in their designation), you can count them. Though still limited to 320 points (known as the Compound Limit Rule – see Basic Rule 6), combining all eligible patterns is a must.

As you work to create a winning hand, keep in mind other patterns which your hand may qualify for. It’s this rule which can turn the 5- and 10-point patterns into a respectable winning hand. Two Identical sequences at 10 points may not sound like much. However, do it concealed and without using terminals or honor tiles, now you have a decent 20-point hand. (Two Identical Sequences 10 points, Concealed Hand 5 points, All Simples 5 points).

Basic Rule 5 – The Minimum Requirement

Basic Rule 5 simply stated is “you can go out on any hand that’s 4 sets and 1 pair (i.e. a Regular Hand).” Yes, even if it has no patterns, you can still go out. This differs from many other mahjong variants, in which you must have at least one pattern of a certain difficulty level to go out. In Zung Jung, this makes it much easier to fold your hand – going out with a low-scoring hand before your opponent can finish their high-scoring hand.

A patternless hand (colloquially known as a chicken hand) scores a token 1 point, so you won’t be winning any matches just going for a quick win every hand. Nevertheless, this is something to always keep in your back pocket. If you think your opponent is about to finish a monster hand, avoid discarding into them and bail.

Note: Some people and some tournaments (including the World Series of Mahjong) use an official variant where you cannot go out on a chicken hand. Keep in mind when sitting down to play whether that rule is in effect. In order to fold, you would need a 5-point pattern at a minimum to go out.

Payoff Scheme Item 4 – Discarder Pays for Big Hands

Zung Jung has a Standard Score, more commonly known as the Par Score, of 25 points. This means any hand 25 points or less, everyone pays out the winner equally. However, for hands worth more than 25 points, if you discarded the tile the winner used to finish their hand, then you pay the lion’s share of the points to the winner. This is commonly known as dealing in or discarding in to your opponent. As we recall, the winner gets 3 times his hand value paid out to them in points. If you dealt in to someone’s Pure One Suit worth 80 points, your opponents only pay out 25 points each. On the other hand, you suffer unequally as you must pay out 190 points (240-50), the remainder. In Zung Jung, you truly pay for your mistakes.

Articles could be written about how this impacts the game at length (I’ll probably end up writing a few myself). No longer is the game only focusing on what you are making. You also have to keep an eye on what your opponents are working toward, and what you discard. Otherwise, you will bear the brunt of the shame and punishment of letting an opponent win.

Payoff Scheme Item 5 – The Rule of Same-Round Immunity

While Item 4 revealed the danger of discards, Item 5 provides a small way to keep yourself safe. In short, this item states that if you discard the same tile that someone else just discarded, and the winning player claims the tile off of you and not the first guy, you don’t get punished. Instead, the person who first discarded the winning tile is considered the discarder and they are the one who pays up as per Item 4.

What this means is discarding a tile identical to one just discarded is considered a safe move. Now this only lasts one cycle, one go-around the table from the winning player’s last discard. This doesn’t apply to discards made 10 turns ago. It even applies to the winner. The ploy of the winner discarding a tile they could have won with in hopes that one of the other players would discard the same tile (and thus hit them with the discarder payout penalty) doesn’t work. In that case, the hand is scored as though the winner self-drew the tile. This reinforces the idea that discarding a tile identical to one just discarded is a safe move.

Understanding how the rules impact playing the game is crucial to improvement. Hopefully this quick discussion gives you some food for thought about your own game.

Tell me your thoughts and experiences down below!

  1. Hi, I just found your website!

    It totally rocks!! It’s hard for me to be objective about it, because I’ve been an ardent ZJ fan since me and my relatives learned mahjong for about 4 years ago. I think it was my mathematical side of me that just clicked when I understood that ZJ’s simple addition method was an application of “orthogonality” of hand characteristics.

    I live in Gothenburg, Sweden, and people in the mahjong community here have sometimes heard about ZJ and maybe have even tried it once or twice, but often people haven’t even heard about it.

    My hobby is inventing new mahjong hands and new inventive mahjong mechanics, though I haven’t published anything yet. (I did put forward some ideas around the chicken hand, in a frantic article “Free the Chicken,” but it was pretty much immature rambling!)

    But about the “chicken hand”/regular hand/patternless hand: I recently read Alan Kwan, in a webpage he wrote a long time ago(?), suggesting to adapt 5 points for just the act of going mahjong in a family setting. (I think I have the link somewhere). When you think about it, it makes good sense, and I don’t think it dilutes the other points, not even the low 5 and 10 points. I can understand why it got dropped in advanced play, but for casual players I’ve experienced a certain anti-climax if nothing happens when someone goes mahjong with a pointless hand: it feels kinda …pointless.

    I began putting together a mahjong site, but got bogged down by the fact that I’m unemployed and am searching for a job right now. Regardless, I’ve developed a prototype for a fu mini-point point system that accompanies the zung jung point system. It’s because my relatives loves getting points for _everything_, even when not getting mahjong, so I’ve tried to broaden the point system in that direction, I’m hoping to soon share it with the world of family playing mahjong folks! And who knows, it might boost the zung jung tribe!!

    Best regards & keep it up! I’ll be visiting from time to time, and will try to find opportunity to share this site!

    • Hi Thomas,

      Glad you found us and are enjoying the site so much! I definitely love the elegance of the scoring system – it’s one of the biggest things that drew me to Zung Jung. It’s simple, it’s easy to understand, and it’s easy to teach. I always found Riichi’s fu/minipoints to be a big chore and a big barrier to entry for new people, among other things that Riichi has. I enjoy how ZJ’s focus is on the skill-based acquisition of points, rather than the luck-based and happenstance-based way that happens often in Riichi.

      The chicken hand always has been a big point of contention in the Mahjong community at large. I, myself, tend to be okay with it most days. I think it’s inclusion lends something to the game, both in teaching and in the gameplay itself. There is a big bait-and-switch, I think, when you teach people your job is to make four sets and a pair and then you have to say “well, it needs to be four sets and a pair *and* it needs to be something else.” At least the chicken hand allows you to go out and learn on our own that earning 3 points a hand is not likely to win you many full games. It also plays a role in folding that I think is adds more to the game than it detracts.

      I do know a good number of people and organizations, including during the World Series of Mahjong a number of times, establish the rule of a 5-point minimum to go out. I think that is a fine rule choice – it is almost as easy to fold with a 5-point hand as it is a chicken hand, but it does allow usually for a little more time to build the larger patterns, which is a good deal of fun. I personally don’t get bent out of shape if people have strong opinions one way or another. I go with the flow, because I’d rather just play Zung Jung either way than argue about chicken hands!

      Sorry to hear about your mahjong site not getting off the ground, but if you have any interesting things you’d like to share or topics for me to chime in on, feel free to let me know! zungjungmahjongdotcom@gmail.com is my email address for site business.
