Self-Pick vs. Called Mahjong Explained
A self-pick occurs when a player draws the tile that completes mahjong from the wall. A called mahjong occurs when a player claims another player's discard as the final winning tile. Both can produce a valid hand, but the source of the last tile can affect scoring, payment conventions, and how players reconstruct the finish.
Two ways to receive the winning tile
Self-pick
The player draws from the wall, recognizes the complete hand, and declares mahjong before discarding.
Called mahjong
The player claims the current discard because it completes the entire valid hand, including a final single or pair when allowed for winning.
Concealed hands may still call the winning discard
A concealed hand cannot make ordinary exposures during play, but it may generally claim the final discard that completes mahjong. The hand remains concealed for card purposes because the call occurs only at completion rather than creating an intermediate exposure.
The table should still verify the exact line, natural-tile positions, and joker restrictions before scoring the hand.
Record the finish accurately
- Identify whether the tile came from the wall or discard area.
- Keep the winning tile visually distinguishable until verification is complete.
- State the exact card line and value.
- Confirm whether the hand was concealed, exposed, or jokerless.
- Apply only the scoring or payment convention agreed upon before play.
- Do not move other discards or exposures until any question is resolved.
Scoring conventions vary by table
Many groups treat self-pick differently from a win on a discard, but the exact payment method may vary. Agree on the scoring system before the first hand and use the current official guidance or event rules when playing in an organized setting.
Winning-source questions
Can a self-picked joker complete mahjong?
Yes, if it fills an eligible matching group of three or more.
Can a called tile complete a pair?
Yes, when it completes the entire valid mahjong. It could not have been called earlier merely to expose the pair.
Does calling the final tile expose a concealed hand?
No intermediate exposure is created; the complete hand is revealed for verification after the winning call.
