3) How to know you are Mahjong
01
1) Build wall and deal
- Shuffle all 136 tiles face down and build 4 walls, each 17 tiles long and 2 tiles high.
- Push walls into a square and keep the right side of each wall section open.
- Determine East, then use dice to choose where the wall opens.
- Set dead wall (14 tiles, including the 2 loose replacement tiles).
- Deal 13 tiles to each player, East takes a 14th and starts by discarding.
02
2) Turn cycle and discards
- Core loop: draw one tile, discard one tile.
- Play order is counterclockwise: East -> South -> West -> North.
- Chow can only be called by the next player in turn.
- Pung and kong can be called by any player; they have priority over chow.
- If a call is made, turn order jumps accordingly (players in between can be skipped).
- If no one calls, next player draws from live wall and continues.

3) How to know you are Mahjong
- Standard hand shape: 4 sets + 1 pair (14 tiles total).
- A set is either a chow (sequence), pung (3 equal), or kong (4 equal, declared).
- A waiting hand means you are one tile away from Mahjong.
- Winning tile may come from your own draw or another player's last discard.
- In NTS, a valid Mahjong normally needs enough value (minimum doubling requirement), except irregular limit hands.

How to calculate points (NTS)
In Dutch tournament Mahjong, first count base points, then apply doubles. Limit hands have fixed values. In this app you enter final winner points per hand; settlement is then calculated automatically.
Counting order
- Count base points for pungs, kongs, pair and mahjong bonuses.
- Add all base points together.
- Apply winner doubles and doubles for all players.
- For limit hands, use fixed value instead of normal detail scoring.
- Cap hand value at the configured points limit (default 2000).
Formula
final points = base points * 2^(winner doubles + shared doubles)
NTS scoring is additive first, multiplicative second. A hand can only be declared Mahjong with enough value under table rules.
Cap note: by default the app uses 2000 as maximum winner points per hand.
Core base points reference
| Combination type | Open pung | Closed pung | Open kong | Closed kong |
|---|---|---|---|---|
| Simple tiles (2-8) | 2 | 4 | 8 | 16 |
| Honors/terminals (1, 9, winds, dragons) | 4 | 8 | 16 | 32 |
- Pair of dragons, own wind or prevailing wind: +2 points.
- Mahjong bonus: +20 points.
- Self-draw Mahjong: +2 points.
- Special win-tile bonuses can add extra points before doubling.
Winner doubles (examples)
- Four chows or four pungs in a winning hand.
- Small four winds / small three dragons patterns.
- Winning on last tile, kong-rob or kong replacement tile patterns.
- Hidden treasure style win (all self-drawn).
Doubles for all players (examples)
- Pung/kong of dragons, own wind or prevailing wind.
- Three or four closed pungs / multiple kongs.
- Clean/very clean/pure suit structures.
- Some category doubles do not stack with each other in NTS tables.
Settlement example with East double
Example hand: winner has 40 final points and current East seat is involved.
- If winner is East: each opponent pays double (3 x 80). Winner +240 total.
- If winner is not East: East pays double (80), other two pay normal (40 + 40).
- Each loser gets the opposite negative delta.
- Total deltas of one hand always sum to zero.
Limit hands
NTS defines regular and irregular limit hands (for example Nine Gates, Thirteen Orphans, Four Winds, Three Dragons).
- A limit hand uses fixed points (often 1000 or 2000) instead of detailed meld scoring.
- Irregular waiting limit hands can score half value when another player wins.
- In this app, mark limit hand and enter final winner points directly.
