Casino Poker Games: The Main Variants Compared

Online casino poker covers a range of distinct games, each with its own structure, strategy, and house edge. Unlike poker rooms where you play against other players, casino poker pits you against the dealer using fixed paytables and defined rules. The house edge ranges from under 0.5% for video poker played with optimal strategy to over 5% for Caribbean Stud - knowing the difference matters if you care about how far your bankroll goes.

The games available here include Video Poker, Oasis Poker Pro Series, TXS Hold'em Pro Series, Casino Hold'em, Double Bonus Poker, and Caribbean Stud Professional. This guide covers how each works, what the house edge is, and which suits different playing styles.

House Edge Comparison by Variant

This table ranks the main casino poker formats from lowest to highest house edge. The figures assume optimal strategy where applicable.

Game	House Edge	Strategy Required
Video Poker - Jacks or Better (9/6 full-pay)	0.46%	Yes - hold decisions matter significantly
Double Bonus Poker (full-pay)	0.17%	Yes - more complex than Jacks or Better
Oasis Poker	1.04%	Yes - exchange and raise/fold decisions
Casino Hold'em	2.36%	Yes - call or fold after community cards
TXS Hold'em	2.19%	Yes - raise preflop, flop, or fold
Caribbean Stud	5.22%	Yes - raise only on AK or better

Side bets (the progressive jackpot in Caribbean Stud, bonus bets in Casino Hold'em) carry much higher edges - typically 20-26% - and are not part of the base game strategy. Avoid them unless the jackpot has grown large enough to change the mathematics, which is rare and documented on dedicated strategy sites.

Video Poker

Video poker is the lowest house-edge format available in a casino. Jacks or Better on a 9/6 full-pay table returns 99.54% with optimal strategy - the 9 and 6 refer to the full house and flush payouts per coin wagered. A short-pay 8/5 table cuts this to 97.3%, so always check the paytable before playing.

The mechanics are straightforward: you are dealt five cards, choose which to hold, and the discards are replaced from the same 52-card deck. Your final hand is paid according to the paytable. There are no community cards and no other players. The decisions are yours entirely - and because the optimal strategy is published and learnable, the house edge figure is achievable in practice, not just theoretical.

Key strategy rules for Jacks or Better: always play five coins (the Royal Flush pays a boosted 4,000 coins at max bet, accounting for a meaningful share of the RTP); break a low pair only if you have four to a Royal Flush; never break a made flush or straight except for four to a Royal Flush. The full strategy table fits on a single reference card and takes an hour to learn.

Double Bonus Poker

Double Bonus Poker is a Jacks or Better variant that boosts the four-of-a-kind payouts in exchange for reducing the two-pair payout from 2:1 to 1:1. Four aces pays 160 coins per coin wagered (versus 25 in standard Jacks or Better); four 2s, 3s, or 4s pays 80 coins; four 5s through Kings pays 50 coins.

The full-pay Double Bonus table returns 100.17% with optimal strategy - technically a positive-expectation game. In practice, achieving this requires memorising a more complex hold strategy than Jacks or Better, because the dramatically different four-of-a-kind payouts change how you value partial hands. The two-pair payout cut also increases variance significantly. This is a game for players who have already mastered Jacks or Better strategy and want to step up the complexity.

Oasis Poker Pro Series

Oasis Poker is a five-card stud poker variant where you play against the dealer one-on-one. You and the dealer each receive five cards; one of the dealer's cards is face-up. You then choose to raise (2x your ante) or fold. The dealer qualifies on A-K or higher - if the dealer does not qualify, the ante pays 1:1 and the raise is returned.

The defining feature of Oasis Poker compared to Caribbean Stud is the exchange option: before deciding to raise or fold, you can swap one or more cards for a fee (typically 1x the ante per card). This adds a layer of decision-making that reduces the house edge relative to Caribbean Stud if used correctly. The basic raise/fold strategy: always raise on a pair or better; raise on A-K-Q or A-K-J when the dealer's face-up card is lower than your fourth-highest card; otherwise fold A-K hands depending on card matches with the dealer's visible card.

TXS Hold'em Pro Series

TXS Hold'em (Texas Hold'em Bonus Poker) adapts the Texas Hold'em format for casino play. You and the dealer each receive two hole cards, then five community cards are dealt in the standard flop-turn-river sequence. You can raise (2x ante) preflop, raise (1x ante) on the flop, or check through to the river. The best five-card hand wins against the dealer.

The house edge of 2.19% assumes optimal strategy, which is complex because the decision tree includes all preflop hand combinations. Simplified rule: raise 2x with any pair, any two cards ten or higher, any ace, and most suited connectors above 5-6. The game also includes a bonus bet that pays for strong hole card combinations (pairs, suited cards, connected cards) regardless of the final outcome - this side bet carries an edge of around 8% and should be avoided.

Casino Hold'em

Casino Hold'em is a simpler Hold'em variant than TXS Hold'em. You are dealt two hole cards and three community cards (the flop) simultaneously. You then choose to call (1x ante) or fold. The turn and river are dealt, and the best five-card hand using hole cards and community cards wins against the dealer.

The dealer qualifies on a pair of fours or better. If the dealer does not qualify, the ante pays 1:1 and the call is a push. The house edge is 2.36% with optimal play. The call/fold decision is simpler than TXS Hold'em: fold only on the weakest hands where you have neither a pair nor a reasonable draw given the three community cards on the flop. Most hands warrant a call.

Caribbean Stud Professional

Caribbean Stud has the highest house edge in this group at 5.22%, but it is one of the most straightforward to play. You receive five cards; the dealer shows one face-up card. You either raise (2x ante) or fold. The dealer qualifies on A-K or better - if the dealer does not qualify, the ante pays 1:1 and the raise is returned.

Basic strategy: always raise with a pair or better; always raise with A-K-Q or A-K-J regardless of the dealer's card; for A-K hands below A-K-J, raise if your fourth-highest card matches the dealer's face-up card, or if the dealer shows a 2-Q and you hold that rank. Fold all hands weaker than A-K. Following this reduces the house edge from its worst case - complete guessing - but 5.22% remains substantially higher than the other variants on this page.

Caribbean Stud typically includes an optional progressive jackpot side bet paying for royal flushes and other premium hands across all active tables. The edge on this bet is around 26% at standard jackpot sizes. It becomes marginally favourable only when the jackpot reaches very high levels, which is rarely publicly advertised or verifiable in real time.

Which Casino Poker Game Should You Play?

If minimising house edge is the priority: Double Bonus Poker at 0.17% is the best available, though it demands more strategy knowledge. Jacks or Better video poker at 0.46% is more learnable and still returns far more than any table variant.

If you prefer the social feel of community cards and dealer interaction: TXS Hold'em and Casino Hold'em sit in the 2-2.5% range, which is acceptable. Oasis Poker at 1.04% offers a middle ground between video poker simplicity and table poker structure.

Caribbean Stud is the most widely recognised casino poker name but carries the worst odds of the group. The name recognition is historical rather than strategic.

What is the lowest house edge casino poker game?

Double Bonus Poker on a full-pay table has a house edge of 0.17% with optimal strategy, making it the best-returning casino poker format available. Jacks or Better video poker on a 9/6 full-pay table returns 99.54%, with a house edge of 0.46%. Both require learning the correct hold strategy to achieve these figures.

What is the difference between video poker and table poker?

Video poker is a single-player machine game where you draw five cards, choose which to hold, and are paid according to a fixed paytable. Table poker variants like Caribbean Stud, Oasis Poker, and Casino Holdem put you head-to-head against the dealer with a structured raise-or-fold decision after seeing some of the dealer cards. Video poker generally offers a lower house edge than table poker variants.

What is the basic strategy for Caribbean Stud Poker?

Always raise with a pair or better. With A-K, always raise if you hold A-K-Q or A-K-J. For other A-K hands, raise if your fourth-highest card matches the dealer face-up card, or if you hold the same rank as the dealer card and your hand includes a card ranked 2 through Queen. Fold all hands weaker than A-K. Following this reduces the 5.22% house edge to its minimum.

Why does the Royal Flush payout matter so much in video poker?

At maximum five-coin bet on Jacks or Better, the Royal Flush pays 4,000 coins rather than the standard per-coin rate. This bonus payout is a significant contributor to the 99.54% RTP. Playing fewer than five coins removes this bonus, reducing your effective return. Recommended approach: play maximum coins and adjust the coin denomination to suit your session budget rather than reducing coin count.

What is the difference between Oasis Poker and Caribbean Stud?

Both are five-card stud variants played against the dealer with one dealer card face-up. Oasis Poker adds a card exchange option before the raise-or-fold decision: you can swap one or more cards by paying a fee of 1x the ante per card. Used correctly, this exchange option reduces the house edge from Caribbean Stud's 5.22% to around 1.04% for Oasis Poker.

Do side bets in casino poker games offer good value?

No. Side bets in casino poker - the progressive jackpot in Caribbean Stud, bonus bets in Casino Holdem and TXS Holdem - typically carry house edges of 20% or higher at standard jackpot sizes. The main game is always the better value proposition. The progressive jackpot in Caribbean Stud can occasionally become mathematically favourable at very high jackpot levels, but this is rare and difficult to verify in real time.
