American mahjong tips: the strategy canon by phase of play
The strategy experienced players teach, organized by the moment you’ll need it.
Treat every Charleston pass as a move: never pass a pair, and aim at one section of the card while two or three of its hands are still alive. Hold off calling until you’re about seven tiles toward mahjong, switch hands when your key tiles stop showing, and never switch after exposing. Count the jokers and every visible copy of a tile, and shift from offense to defense as the wall runs down.
This guide covers standard American mahjong. Tile artwork and house rules can vary; use the rules and card agreed on by your table.
The Charleston
Six passes decide most hands before the first draw, so treat every pass as a move.
- Never pass a pair. If you must break one up, split it across two different passes so nobody collects it whole.
- Pass singletons that fit few hands: stray winds, unmatched dragons, lonely numbers far from your sections. Keep tiles that appear in several card sections.
- Continue into the second Charleston only if you still have three or more tiles you’re happy to give. With fewer than that, stop it.
- Track what you pass and what comes back. A neighbor who keeps your bams is building bams; stop feeding them.
- In the courtesy pass, the optional trade with the player opposite, give only what you’re completely done with. Never make one with a player who stopped the Charleston; they just told you they’re close.
- Blind passes, where you send incoming tiles on unseen, belong to the first left and the last right. Use them when your rack has nothing left to give: pass along one to three tiles unseen and keep your good tiles.
Choosing a hand
Beginners lose more hands at this step than at the wall.
- Pick a section, not a hand. By the Charleston’s end you want seven or eight tiles pointing at one family of the card, with two or three lines (individual hands) still alive inside it.
- Follow your tiles. Count suit concentration, existing pairs and jokers before you commit to anything, whatever hand you were hoping for.
- Prefer hands where every group takes jokers. Pairs can’t use them, which is exactly why pair-heavy hands pay more and hurt more.
- New to the card? Live in the year hands, consecutive runs, and winds sections. Quints and singles-and-pairs are for later.
- Sort your rack the same way every time. The card’s shapes start jumping out at you before you consciously look.
When to switch
Knowing when to switch is one of the hardest skills in the game.
- Switch when your key tiles haven’t shown in five to seven draws, when an opponent exposes what you need, or when the third copy of your pair tile hits the discards.
- A simple hand 80 percent done beats a rich hand half done. Sunk cost is the enemy.
- Never switch after exposing, that is, after calling a discard and laying the group face up. Your calls lock you into hands that contain those exposures.
- Don’t switch when you’re one away. Late panic loses more hands than cold waits do.
- Accidental jokers are a reason to look again: two extra jokers can put a bigger line in the same section within reach.
Calling and exposures
Every call buys a tile and sells information.
- Don’t call early. Aim to be about seven tiles toward mahjong before your first exposure; the ideal call is the one that leaves you a tile or two from winning.
- Three exposures narrow you to a couple of lines and the whole table plays around you. Sometimes the quiet path wins.
- A discard plus two jokers is a legal call. No natural tile is required.
- Remember what calling costs concealed hands: everything. A C hand, one marked concealed on the card, may only claim its winning tile.
Jokers
There are eight jokers in the set, and the player who counts them owns the endgame.
- Redeem exposed jokers (swap in the natural tile and take the joker) whenever you legally can, even when you don’t need the joker. Denying the table is worth the tile.
- Save jokers for scarce tiles. If plenty of a tile is still live, wait and draw it instead of spending a joker on the first gap.
- Spread jokers across two exposures rather than stacking one, and expose them late; a joker showing on your rack is a redemption target.
- Count the eight. When most jokers are visible, pivot away from quints and other joker-hungry lines.
- To bait a joker, discard one of a pair you don’t need. If someone claims it into an exposure with a joker, your remaining copy buys that joker back.
- A player who discards a joker is telling you they’re nearly done. Tighten up immediately.
Defense and reading the table
The gap between average and good players is entirely here.
- Count what you can see. Every suit tile, wind and dragon comes four to a set, so if three 6 craks are visible, stop waiting on the fourth.
- Read exposures as sentences: consecutive numbers mean run hands, and the same number across suits means like numbers.
- Early discards show what a player is not collecting. A player who suddenly stops discarding a suit is hoarding it.
- Late in the hand, the safest discards are tiles already thrown that nobody called. A joker is safer still, since a discarded joker can never be claimed.
- Shift with the wall: play mostly offense early, half and half by mid-wall, and pure defense when your hand dies. Feeding a hot hand is the only true sin.
- A player discarding nothing but winds and flowers late is set and dumping safe tiles. Believe them.
The table itself
Speed, money and manners are the parts no rulebook teaches well.
- Decide your discard before your turn; slow play is the one thing every table punishes.
- At quarters tables, the card value is the price, the thrower pays double, a self-pick (drawing your winning tile from the wall) doubles everyone, and jokerless doubles the value (singles and pairs hands, which can never hold a joker, don’t get that double). Nobody pays on a wall game, when the tiles run out with no winner.
- Most tables keep score by games won. The points price the payout; the bragging is in the wins.
- A 20 percent win rate is a good first month. Three of four players lose every hand; play for the reads.
- Name your discards out loud, leave gaps between exposures, and coach newer players with words, never hands.
Common questions
When should I stop the Charleston?
Continue into the second Charleston only if you still have three or more tiles you’re happy to give. With fewer than that, stop it.
When should I switch hands?
When your key tiles haven’t shown in five to seven draws, when an opponent exposes what you need, or when the third copy of your pair tile hits the discards. Never switch after exposing, and don’t switch when you’re one away.
How early should I call a discard?
Aim to be about seven tiles toward mahjong before your first exposure. The ideal call is the one that leaves you a tile or two from winning.
Should I pass a pair in the Charleston?
Try not to pass a pair in the Charleston. A joker cannot stand in for half a pair, and a discard cannot be called for one unless it wins the hand, so pairs are the hardest tiles to rebuild. If you must break one up, split it across two different passes.
What is the safest discard late in a hand?
Late in a hand of American mahjong, the safest discard is a joker, because a discarded joker can never be claimed. After that come tiles already thrown that nobody called. Count the visible copies too: a tile with three copies showing can no longer complete anyone’s pair.
Can I call a discard with two jokers?
Yes. In American mahjong a discard plus two jokers is a legal call for a pung, and no natural tile is needed beyond the discard itself. Jokers can fill any or all of the other spots in a called pung, kong, quint or sextet.
