Decisions, not guarantees
Mahjong strategy tips
Choose a reachable line, protect its natural pairs, and check what remains available before you call. Start with the worked example below, then use the checklist during your next practice hand.

Can this natural pair still be completed?
You hold one 6 Bam. Another player has exposed a natural pung of 6 Bam. There are only four natural copies.
Your rack: 1 copy
Their exposure: 3 copies
Work out what remains
4 total − 1 in your rack − 3 locked in their exposure = 0 available. You cannot finish a natural pair of 6 Bam in this position. A joker cannot rescue that pair. Choose a target that does not need it.
If their group instead contained two natural 6 Bams and a joker, one natural copy could still be elsewhere. That means possible—not guaranteed. A discarded tile cannot be picked up later.
- Name two plausible lines. Check which exact singles and pairs each still needs.
- Count visible natural copies. Include your rack, exposures and discards.
- Separate repairable gaps. Eligible groups can use jokers; singles and pairs cannot.
- Choose the practical target. A higher printed score does not compensate for an impossible required pair.
Pick a line you can already see
Before the first pass, look for a line the rack is already close to, and a second line that shares its tiles. On this card, Even fire (pungs of 2, 4, 6, and 8 in one suit, plus a flower pair) and Garden steps (four consecutive pungs in one suit, plus a flower pair) are readable shapes at 25 points. Blooming trio, the same number across three suits with a dragon and a flower pair, is another.
Quiet path and the other concealed pair hands pay 50, or 40 in the case of Dragon thread, and they give you nothing to call until the end. They are a good second plan when you were dealt pairs. They are a poor first plan when you were dealt jokers and almost no pairs, because a joker cannot sit in a pair. The tile guide is the constraint. The score is the reason the quieter hands are printed higher.
Pass with both lines in mind
Pass tiles that fit neither line. Keep jokers: you are not allowed to pass them anyway, and a joker is often the tile that finishes a pung the deal did not. Flowers are the most flexible family, since any two of them are a pair. If your line wants a flower pair and you hold two, passing one reopens a gap you had already filled. Do it only if another target gives you a better reason.
The first Charleston is also news. What comes back from the right is what that player chose to give away. It is a hint about what they are not collecting. It is not a promise about what they are collecting.
Vote for the second Charleston while the rack is still scattered. Decline when you are already near a line: another three passes can take the tiles you were counting. On the courtesy pass, offer only tiles you are finished with. If you offer three and the player opposite offers one, a single tile moves.
Calling commits you
An exposed pung is useful when it is exactly a group on the line you are playing. It also gives the table information about your possible lines, and it crosses off every concealed hand. Call when the group is real progress. Leave the discard when you are still choosing between two lines that want different tiles.
A call does not draw a replacement. Players coming from Chinese mahjong feel this most with a kong: you expose four, and then you discard, still inside fourteen tiles. The rules spell that out. Expecting an extra draw is how a legal-looking call produces a hand that no longer matches anything.
A natural pung is worth more than it looks when the line can be jokerless. The double takes a 25-point self-pick from 150 to 300. Spending a joker to call a group you could have filled with naturals gives that double away. Spending a joker because the fourth natural is already on the table is a different decision: the line may be dead without it.
Count what is already dead
Four copies is the whole supply of a number, a wind, or a dragon. If three 6 bams are already exposed in someone else’s pung, one 6 bam remains. A pung of 6 bam now needs jokers. If you already hold one 6 bam, that fourth copy is the one you hold: none remains to complete your natural pair. A joker cannot replace it. If all four are visible and you hold none, a line that needs even a pair of them is finished, and so is any minute you spend on it.
Jokers change the arithmetic for groups of three or more, not for pairs. They do not change it for a tile that the line needs as a single. When two lines still fit, prefer the one that survives the tiles you can see.
Take the hand that can win
A 45-point line you are four tiles away from loses to a 25-point line you are one tile away from, once the discards say the suit is gone. A wall game pays zero to everyone. The smaller finished hand is the one that changes the score.
In a practice match the coach can name one suggested move and a short reason, or play a step so you can watch it. Use that while the card is unfamiliar. Then turn it off for a hand and notice which line you would have chosen yourself. There is no timer on either kind of table, so opening the card at full size is part of playing, not a delay.
Common questions
Should I always play the highest line on the card?
No. The highest lines are concealed pair hands, and only some deals are close to them. A 25-point line you can finish outpays a 50-point line that is still missing a pair when the wall ends.
When should I skip the second Charleston?
When your tiles already suggest a line and another round of passing is more likely to break it than to help it. If you are still holding a bit of everything, the extra passes are usually welcome.
Is calling always better than staying concealed?
No. A call commits you to lines that allow exposures, and it shows the table a group. It is the right call when that group is on your line. It is the wrong call when you are still deciding, or when you are playing a concealed hand.
What should I keep in the first pass?
Jokers, a flower pair if your line wants one, and the tiles that fit the line you are actually playing. Pass tiles that fit neither that line nor a nearby backup. You cannot pass jokers even if you want to.
