Siamese Mah Jongg

• Scores accumulate on each player's total — not zero-sum like a 4-player settle-up.
• Self-picks are NOT doubled in Siamese (unlike standard NMJL home games).
• 1st Mah Jongg: card value from the card; jokerless doubles — but not on Singles & Pairs hands (leave jokerless off for those).
• 2nd Mah Jongg: double the card value; jokerless doubles again on that hand (same Singles & Pairs exception).
• Both mahjs at once: double the combined score for both hands.
• Discard claimed for opponent's 2nd mahj: the thrower takes a penalty (default −25).
• Wall game with no mahj exposed: everyone gains wall points (default +10).
• At session end, the lower score pays the winner the difference.

• Each mahjong as it happens — 1st, 2nd, or both at once
• Hand value from the 2026 NMJL card (or Siamese card if you use one)
• Jokerless only when the hand uses the jokerless bonus — never for Singles & Pairs
• 2nd-MJ discard penalties when someone feeds the winning tile
• Wall games when no mahj was exposed

• 1st Mah Jongg

  Their first exposed winning hand this round.

  Winner banks the card value (×2 if jokerless — not on Singles & Pairs).

• 2nd Mah Jongg

  They completed both racks — the second hand pays double.

  Winner banks double the card value (×2 again if jokerless — not on Singles & Pairs).

• Both at once

  Both hands declared and won on the same turn — scores doubled again.

  Winner banks twice the sum of a 1st and 2nd mahj score for that hand value.

• 2nd MJ discard penalty

  A discard was claimed for the opponent's second mahj — the thrower loses points.

  Subtract penalty points from the discarder only — no change for the winner's running total from this row alone.

• Wall game

  No mahj was exposed before the wall ran out — everyone gains wall points.

  Add wall points to every player at the table.

A 25-point 1st mahj (not jokerless) → +25. Later a jokerless 2nd mahj at 30 → +120 (30×2×2). A wall game → +10 each.
