5,10,K · house extension · 6 · Rules
Two decks with jokers: five players get 21 each with 3 public reserve cards; six get 18 each.
5,10,K score 5/10/10. The trick winner captures scoring cards from ALL plays in that trick. Mixed 5,10,K < suited 5,10,K < bombs < rocket; equal rockets do not beat each other. Five-player individual play ends at first out; six-player alternating teams end when an entire team is out. Captured points decide winners, not first out. The five-player reserve is unclaimed. These are explicit house extensions, not a national standard or four-player Hunan rules.
