No "closed room"

  • Result of the rubber is calculated only by the score of the boards played.
  • Additionally, the boards can be analyzed by the "Dummy Double Solver". (You have to enter all cards for all four hands).

Scoring for the "closed room" is calculated by the app.

  • Score for the "closed room" is the "optimum" bid calculated by the "Double Dummy Solver".
  • All cards for the four hands are required.
  • You are competing with "perfect" players in the "closed room".
