The rules state:
If two or more cards share the top value or data is not available for that particular subject then all the cards are placed in the middle and the same player chooses again from the next card. The winner of the hand takes the cards in the middle as well.
However, what they don't make clear is:
- Does every player continue to play in this case? (If two players have the same top value and a third player does not, does the third player continue to play – and possibly even win the hand?)
- What happens if this situation occurs on a player's last card? They cannot carry on but have not yet lost the hand!
Is there some de facto rule that's used in each of these circumstances? Or is there an official rule that is just hard to find?
