Four of a Kind is a hand with four cards of the same rank.
Explanation. Also known as “quads,” it’s one of the highest-ranking poker hands—e.g., 7‑7‑7 on board with pocket 7 gives quads. The name is literal. This hand beats full houses and is rare, often played for maximum value. Recognizing quads rapidly helps avoid slow-playing mistakes or misreading relative strength.
