The short answer: the goal is a complete hand of 14 tiles made of four sets plus a pair. A set is three tiles in sequence (chow), three of a kind (pung), or four of a kind (kong). You win by drawing the final tile yourself or taking a discard.
Mahjong looks like a wall of confusing tiles the first time you sit down. Underneath, it is one race: everyone builds the same shape and the first one to finish wins. Get the target shape in your head and the whole game clicks.
What counts as a complete hand?
You are building four sets plus one pair. That adds up to 14 tiles:
- Chow: three tiles in sequence in one suit, like 3-4-5 bamboo.
- Pung: three identical tiles, like three red dragons.
- Kong: four identical tiles. It counts as one set and you draw a replacement tile.
- Pair: two identical tiles, the only part that is not a set.
How do you actually win?
- Hold 13 tiles and draw a 14th from the wall.
- If it completes four sets plus a pair, call out and win on the spot.
- Otherwise discard one tile and keep 13.
- You can also win on another player’s discard if it finishes your hand.
Most variants add a minimum-point requirement on top. The target shape itself never changes.
Does the objective change in other versions?
Only in American mahjong. Instead of any four sets and a pair, you build hands listed on the National Mah Jongg League’s yearly card, with jokers that act as wild tiles. If you are learning in North America, read our American mahjong guide before your first game.

Related Questions
Can you win with fewer than 14 tiles?
No. Between turns you hold 13 tiles, and the winning tile is the 14th. A kong lets you draw a replacement, but it still counts as one set.
What if you have seven pairs instead?
Seven pairs is a special winning hand in most versions. You skip the four-sets-plus-pair shape and win with seven matching pairs, usually for more points.
What happens if nobody wins?
When the wall runs out, the hand ends in a draw. Nobody scores, the tiles are reshuffled, and the next dealer starts. Draws are more common than beginners expect.
