Poker hand rankings define the universal hierarchy of 5-card hands in poker standards, ranging from Royal Flush (1 in 649,740) down to High Card. Flushes beat Straights, Full Houses beat Flushes, and Four of a Kind beats Full Houses. Ties are broken by the highest ranked cards within the combination, followed by kickers.

Uno is a 108-card shedding game governed by official Mattel standards. Official rules strictly prohibit stacking draw cards (+2 on +2 or +4 on +4); affected players must draw and forfeit their turn. Players may legally finish on action cards, and a Wild Draw 4 may only be played when holding no cards of the active color.
