Am I playing this game correctly...
The active player has 2 opportunities to cross off numbers; she can choose the white dice (open to all) AND she can choose the colored dice pairing?
OR, she can only choose either the white or the colored pairing...not both?
IF she chooses neither pairing a penality is is marked.
I have been playing that the active player can choose both pairing to cross off numbers if she decides to do so.
You played it correctly. If the active player uses both pairings, it is important that he has to make the cross for the white dice before he makes one for the white/colored pair.
