How the score is built

  • Trick values (per trick bid above 6): ♦♣ 20 · ♥♠ 30 · NT 40 first, 30 after.
  • Doubled ×2, redoubled ×4 on bid tricks.
  • Game when bid-trick points reach 100: +300 not vul, +500 vul. Otherwise part-score +50.
  • Small slam +500 / +750 vul. Grand slam +1000 / +1500 vul.
  • Making a doubled contract +50; redoubled +100 (the "insult").
  • Overtricks: undoubled at trick value. Doubled 100 each (200 vul). Redoubled 200 each (400 vul).
  • Undertricks: see the table opposite.

Minimum games: 3NT, 4♥, 4♠, 5♣, 5♦. Doubled, 2♥/2♠ and 2NT reach game (120+); 1NT, 2♣/2♦ and 1♥/1♠ redoubled do too.

Undertrick penalties

Doubled: 100/300/500 then +300 each not vul; 200/500/800 then +300 each vul. Redoubled is twice doubled.

Contracts made exactly

Add an overtrick at the trick value: +20 minors, +30 majors and NT.

Doubled contracts made

Each doubled overtrick adds 100 not vul, 200 vul.
