A wheel is the best possible low hand in many lowball or split-pot games: A‑2‑3‑4‑5.
Explanation. Often called steel wheel, wheel is the lowest five-card combination in lowball formats. The term comes from literal wheel pattern of these ranks. Holding the wheel gives nut-low in Hi‑Lo or winning hand in Ace-to-Five lowball. Recognizing wheel combos is key to mixed-game strategy.
