More rules, more fun
No-trump
When choosing trump, there’s in fact a fifth possibility: no-trump. Choose no-trump if you have many manilles and other high cards. No-trump also means that the points are doubled at the end of the deal.
Blind
If you choose a trump before taking a look at your cards, points are doubled. The dealer gets to lead the first trick then. This means if you choose no-trump without looking, points are quadrupled.
Tapping the table
If the opposing team believes they can beat the chosen trump (get more than 30 points) then they can 'tap' the table to double the points at the end of the deal. If the opposing team 'tapped' the table and the trumping team believes the opposing team will not win the deal, they may 'double tap' the table, automatically quadrupling the points of the deal.
A round without winner
If one round ends in 0 points – both teams count 30 points – the result of the next round must be doubled.
Counting
If there have been any doubles or redoubles (for example when you play no-trump and the opposing team taps the table), these are applied after counting the total of the round.
