This option is especially suited for those who want two programs to play against each other on two computers. You need a special cable for it plus software which no doubt your dealer can supply you. The advantage of Rebel is that, when you let two computers play against each other, Rebel will save all games into the current database including the score. During this autoplaying the score is visible and updated and double games are skipped automatically! Above the move window you will see for instance: 12.0-9.0 10-4-7 (6) meaning: the score is 12-9 for Rebel, 10 games are won, 4 drawn and 7 lost, while 6 double games are skipped.
