Omaha
Community-card poker like Hold'em, but with four hole cards instead of two — high hand only, no low split, and exactly two hole cards must be used at showdown.

Rules
Each player is dealt four private hole cards face down. A betting round follows (preflop), using the same blind structure as Hold'em.
Flop, turn, river: three community cards, then one more, then one more, each followed by a betting round — identical structure to Hold'em.
Showdown: each player must use exactly two of their four hole cards (no more, no fewer) combined with exactly three of the five community cards to make their best five-card high hand. Unlike Hold'em, "playing the board" is not possible, since every player must contribute exactly two hole cards. The best high hand wins the entire pot — there is no low split (that's Omaha Hi-Lo, a separate variant).
Strategy notes: Because every player has four hole cards but must use exactly two, hands that look huge at a glance (four cards to a flush, or two pairs) often can't actually be played as intended if the suits or ranks don't combine correctly with the board — this "exactly two" rule is the single biggest adjustment for players coming from Hold'em, and average winning hands in Omaha run considerably stronger than in Hold'em since so many more hole-card combinations are in play across the table.
Common house rules
Confirm high-only before the deal
Because Omaha Hi-Lo is so common, it's worth explicitly stating 'high only, no low split' before dealing plain Omaha at a mixed dealer's-choice table to avoid confusion at showdown.
Pot-limit by tradition
Omaha is very commonly played pot-limit rather than no-limit or fixed-limit, since the stronger average hands mean uncapped no-limit betting can get out of hand quickly — many home games default to pot-limit for this game specifically.
Five-card Omaha variant
Some tables deal five hole cards instead of four (still using exactly two at showdown) for even bigger average hands — this is essentially 'Big O' without the hi-lo split.
