Poker Variants Guide: Texas Hold'em, Omaha, Stud, and Beyond

Poker is not one game — it's a family of games that share a betting structure and hand rankings but diverge dramatically in how cards are dealt, how much information is public, and what strategic muscles a player actually needs. This page maps the major variants: Texas Hold'em, Omaha, Seven-Card Stud, Razz, and a handful of others worth knowing. Understanding the differences matters whether someone is sitting down at a casino table for the first time or trying to figure out why a Hold'em specialist keeps getting humbled in an Omaha game.

Definition and Scope

All poker variants operate on the same foundational currency: five-card hand rankings, from high card through royal flush, evaluated against one or more opponents. What differs is the mechanism — how those five cards get assembled, and what role community cards, hole cards, or draw mechanics play in the process.

The World Series of Poker, which has run annually since 1970, offers more than 90 bracelet events across different formats, which gives a reasonable census of how many distinct variants are actively played at a competitive level. The most prominent fall into three structural families:

• Community card games — players share face-up board cards (Texas Hold'em, Omaha)
• Stud games — players hold a mix of face-up and face-down individual cards (Seven-Card Stud, Razz)
• Draw games — players receive a private hand and may replace cards (Five-Card Draw, Badugi)

For a grounding in poker's foundational rules and hand rankings, that's a useful starting point before navigating variants.

How It Works

Texas Hold'em deals each player 2 private hole cards. Five community cards are then revealed in three stages — the flop (3 cards), the turn (1 card), and the river (1 card) — with a betting round after each. Players construct the best 5-card hand using any combination of their 2 hole cards and the 5 board cards. The catch: a player can use 0, 1, or both hole cards, which occasionally produces the slightly awkward situation where the best hand is simply the one sitting on the board.

Omaha looks nearly identical to Hold'em on the surface — 4 hole cards, 5 community cards — but carries a structural rule that completely changes the game: players must use exactly 2 hole cards and exactly 3 community cards. No exceptions. This forces stronger hands at showdown (flushes and full houses appear far more frequently) and makes Omaha a game of nuts-chasing rather than one-pair decisions. Omaha Hi-Lo adds a second pot split for the lowest qualifying hand (five unpaired cards ranked 8 or below).

Seven-Card Stud eliminates community cards entirely. Each player receives 7 individual cards — 3 down, 4 up — and must build the best 5-card hand from those 7. Because exposed cards are visible to the table, memory becomes a core card counting and tracking skill. Razz uses the same deal structure but reverses the objective: the lowest hand wins, with aces counted low and straights/flushes ignored.

Five-Card Draw is the variant most people picture from old Western films. Each player receives 5 private cards, bets once, may discard and redraw up to 5 cards, then bets again. Its simplicity makes it a common entry point in learning card games as a beginner, though its strategic ceiling is lower than community-card formats.

Common Scenarios

Three situations illustrate how variant choice changes everything:

1. The flush problem in Omaha. A player holding A♠ 2♠ 9♥ K♦ sees a board of 5♠ 8♠ J♠ Q♣ 2♦. In Hold'em, that ace-high flush would be the nuts. In Omaha, the player must use exactly 2 hole cards — the A♠ and one other — plus 3 board cards, including 2 of the 3 spades on board. The flush is real, but only because the math works out. A player who forgets the "exactly 2" rule here is not playing Omaha; they're playing an imaginary game.

2. Dead card tracking in Stud. In a full 8-player Seven-Card Stud game, by fifth street, 40 cards have been dealt (5 per player). Of those, roughly 24 are face-up and visible. A player drawing to a flush needs to account for how many of their suit have already been folded — a discipline with no equivalent in community card games, where board cards are the only shared information.

3. The kicker collapse in Hold'em. Two players both hold an ace. The board reads A-K-7-3-2. The winner is decided entirely by the second hole card — the kicker. This scenario, common enough to have its own poker terminology, highlights how Hold'em rewards hand-reading over hand-making.

Decision Boundaries

Choosing which variant to play — or to study — comes down to three variables:

1. Information density. Hold'em gives 2 private cards in a world of shared public cards. Stud gives mixed public/private with no sharing. Draw gives maximum privacy. More public information generally means more bluffing and deception opportunities; less public information rewards memory and card-tracking.

2. Hand strength calibration. Omaha's "exactly 2 hole cards" rule inflates average winning hand strength. A two-pair hand that wins a Hold'em pot regularly gets crushed in Omaha. Players migrating between formats need to recalibrate expectations — a process that typically takes 20 to 30 hours of deliberate play to internalize.

3. Table availability. In most US cardrooms, Texas Hold'em accounts for the majority of cash game seats. Omaha Hi-Lo and Seven-Card Stud appear in regular rotations at larger venues. Razz and draw games are primarily found in mixed-game formats like H.O.R.S.E., which cycles through 5 variants in fixed rotation. The card game odds and probability change so substantially between formats that treating them as the same game is the most reliable path to an empty stack.
