About this hand
A flush in poker consists of five cards of the same suit, regardless of sequence. Ranking **5th out of 10** in hand strength (where 1 is the strongest), it defeats straights, three of a kind, two pair, one pair, and high card but is outmatched by full houses, four of a kind, straight flushes, and royal flushes. Among the **2,598,960** possible five-card combinations, **5,108** qualify as flushes. This rarity underscores its strategic value, though it remains more common than higher-tier hands. While powerful in multi-way pots, its vulnerability to four stronger hand categories demands careful play.
