Three Card Poker is one of the simplest table games to learn but one of the easiest to misplay, because the correct strategy isn’t intuitive from the cards alone. There’s exactly one mathematically optimal rule for the Ante/Play decision, and getting it wrong costs real money over a session.
Loading calculator...
This calculator covers both halves of the game. The Ante/Play side tells you whether your hand meets the standard “Q-6-4 rule” for playing versus folding, and shows the built-in house edge you’re facing when you follow that rule correctly. The Pair Plus side is a completely separate side bet with its own paytable and its own house edge, calculated independently.
Because Pair Plus paytables vary between casinos, the calculator lets you select the specific version you’re facing so the house edge figure actually matches the table you’re sitting at, rather than a generic average.
📊 How to Use the Three Card Poker Calculator
Switch to Ante / Play mode first. Select whether your three-card hand meets or falls below the Q-6-4 threshold (any pair, or a Queen-high hand with a 6 or better and a 4 or better as the second and third cards). Enter your Ante wager to see the house edge and expected loss for that round.
The Q-6-4 rule is the single correct strategy for the standard game — there is no situation where deviating from it improves your expected return, regardless of what the dealer’s hand might contain, since you can’t see it.
Switch to Pair Plus mode to analyze the independent side bet. Select the paytable version posted at your table (check the felt — casinos post the exact payouts), enter your stake, and the calculator shows the house edge and per-hand payout probabilities for that specific paytable.
🔢 Calculator Fields Explained
Hand Category – Whether your three-card hand meets the Q-6-4 threshold or falls below it, which determines the correct Ante/Play decision.
Ante Wager – Your initial bet, placed before seeing your cards, which must be matched with an equal Play wager if you choose to continue.
Paytable Version – Which Pair Plus payout schedule applies at your specific table; casinos use several different versions with meaningfully different house edges.
Pair Plus Wager – The optional side bet, resolved purely on your own three-card hand regardless of the dealer’s hand or your Ante/Play decision.
Currency – The symbol used to display wager and expected-value figures. Cosmetic only.
💰 Understanding the Results
| Result Field | What It Means |
|---|---|
| Optimal Decision | Whether the Q-6-4 rule says to Play or Fold your specific hand category |
| House Edge (Ante wagered) | The standard game’s built-in edge when the Q-6-4 rule is followed correctly on every hand |
| Ante Bonus Expected Return | The average payout from the separate Ante Bonus, which pays on a straight or better independent of your Play decision |
| House Edge (Pair Plus) | The edge specific to your selected Pair Plus paytable — this changes materially between paytable versions |
The Ante Bonus is easy to overlook because it doesn’t depend on whether you win or lose the hand overall — it pays purely based on your own three cards forming a straight, three of a kind, or straight flush.
Folding a hand that still qualifies for the Ante Bonus doesn’t cost you that bonus payout — the bonus pays regardless of your Play/Fold decision, which is a detail many players don’t realize.
Deviating from the Q-6-4 rule in either direction — folding a qualifying hand or playing a non-qualifying one — always increases the house edge you face, with no exceptions.
📐 Calculation Formulas
| Component | Basis |
|---|---|
| Hand probabilities | Combinatorics over all C(52,3) = 22,100 possible 3-card hands |
| Ante/Play house edge | Derived from the full game tree of Q-6-4-strategy outcomes against all possible dealer hands |
| Ante Bonus expected return | Sum of (hand probability × bonus payout) across straight flush, three of a kind, and straight |
| Pair Plus house edge | Sum of (hand probability × payout) across all paying categories, minus probability of a non-paying hand |
The straight-flush and flush hand counts in three-card poker are notably different from five-card poker rankings — a flush is actually rarer than a straight in the three-card game, which is why the standard hand ranking order differs from Texas Hold’em.
All of these probabilities are exact combinatorial results, not estimates or simulations — three-card poker has few enough possible hands that the full distribution can be calculated precisely.
📝 Practical Examples
Example 1 – Clear play. You hold Q-8-4. This meets the Q-6-4 threshold (Queen high, with a second card of 8 which beats the required 6, and a third card of 4 which meets the minimum). Correct decision: Play.
Example 2 – Clear fold. You hold J-10-9. Despite being three consecutive high cards, this doesn’t meet the Q-6-4 rule since the top card is a Jack, not a Queen or higher. Correct decision: Fold, even though the hand “feels” strong.
This is the single most common strategy error in the game — players intuitively want to play a strong-looking hand like J-10-9, but the math says fold, because the rule is based on the Queen threshold, not general hand strength.
Example 3 – Ante Bonus independent of Play. You hold a straight, 9-8-7 unsuited, and correctly fold since it’s below Q-6-4 if unpaired… but a straight always qualifies to Play regardless (any pair or better always plays). Note: any straight or trips hand always exceeds Q-6-4 automatically, so this scenario only applies to a non-straight sub-Q-6-4 hand receiving no bonus.
Example 4 – Pair Plus paytable comparison. The same $10 Pair Plus wager carries a noticeably different house edge under the Standard 6-Way paytable versus the Alternate paytable, even though both look similar at a glance. Always check the exact posted paytable before assuming two Pair Plus bets are equivalent — a few percentage points of house edge difference is common between versions.
💡 Tips & Best Practices
Memorize the Q-6-4 rule exactly as stated — Queen high, with a second card of 6 or higher and a third card of 4 or higher, or any pair or better. There is no partial-credit version of this rule that improves on it.
Check the felt for the exact Pair Plus paytable before wagering on that side bet — casinos are required to post it, and the difference between paytable versions can shift the house edge by more than a percentage point.
Remember that folding forfeits your Ante wager entirely, so the Q-6-4 rule already accounts for that tradeoff — it’s not a “safer” choice to fold borderline hands more often than the rule suggests.
Treat Pair Plus and Ante/Play as two completely separate decisions with two separate house edges — your Pair Plus wager size shouldn’t be influenced by what you decide on the Ante/Play side, and vice versa.
If a casino offers a 6-Card Bonus or Prime side bet alongside Three Card Poker, evaluate those separately too — they carry their own distinct house edges unrelated to Pair Plus.
- Never deviate from Q-6-4 based on “feel” — the rule is already mathematically optimal for the information available to you
- Compare Pair Plus paytables between casinos if you have a choice of where to play the side bet
Keep in mind the Ante Bonus is a bonus specifically for straight-or-better hands on the Ante bet — it’s a different mechanism from the Pair Plus side bet, even though both reward similar hand types.
⚠️ Common Mistakes to Avoid
Playing a strong-looking hand that fails the Q-6-4 rule
Hands like J-10-9 or K-2-2’s near-misses can feel strong intuitively while still falling below the mathematically correct playing threshold.
Trusting instinct over the Q-6-4 rule on borderline hands is the most common and costliest strategy error in Three Card Poker, since it directly increases the house edge on every misplayed hand.
Always check the exact rule (Queen-6-4 or better) rather than judging a hand by how strong it “looks.”
Confusing Pair Plus house edge with Ante/Play house edge
These are two entirely separate bets with different mechanics and different house edges — treating them as one combined bet leads to a distorted sense of overall game risk.
Assuming the Ante/Play house edge automatically applies to a Pair Plus wager (or vice versa) is a common misunderstanding — each side bet has to be evaluated on its own specific paytable and probabilities.
Always calculate and reference each bet type’s house edge separately, especially when comparing tables with different Pair Plus paytables.
Assuming all casinos use the same Pair Plus paytable
Pair Plus paytables vary meaningfully between properties, and a table with a worse paytable can carry a noticeably higher house edge for what looks like the same bet.
Always check the posted paytable at the specific table before wagering, rather than assuming a “standard” payout applies everywhere.
🎯 When to Use This Calculator
Use this before sitting down at a Three Card Poker table to confirm you know the Q-6-4 rule cold, and to check the specific Pair Plus paytable’s house edge against the version you’ll actually be playing.
Three Card Poker rewards knowing one simple rule precisely rather than developing complex strategy — this calculator exists to make sure that one rule, and the Pair Plus math around it, is fully clear before you play.

❓ Frequently Asked Questions
Is the Q-6-4 rule really the single best strategy, or can it be improved on?
The Q-6-4 rule is the mathematically proven optimal strategy for the standard game — no adjustment to it improves expected return, since the player has no additional information (like the dealer’s cards) that could justify deviating.
This is different from games like blackjack, where basic strategy varies by dealer up-card — in Three Card Poker, the correct decision depends only on your own three cards.
Why is a flush ranked higher than a straight in three-card poker?
Because a flush is statistically rarer than a straight in the three-card game — the reverse of five-card poker rankings, where straights are rarer than flushes.
This reversal trips up players coming from Texas Hold’em or other five-card games, since the ranking intuition they’ve built up doesn’t transfer directly to three-card hands.
Does the dealer qualifying or not affect my Pair Plus payout?
No — Pair Plus is resolved entirely on your own three-card hand and is completely unaffected by whether the dealer qualifies with Queen-high or better, or by your own Ante/Play decision.
This is what makes Pair Plus a genuinely independent bet rather than a bonus layered onto the base game.
Why do Pair Plus paytables differ between casinos?
Casinos adjust individual payout multiples (particularly on straights and flushes) to tune the house edge to their preferred level — a small change in the straight or flush payout can shift the overall house edge meaningfully given how relatively common those hands are.
Always confirm the exact posted paytable rather than assuming a “standard” version applies — the difference between common paytables can be more than one full percentage point of house edge.
Should I always make the Pair Plus side bet?
That depends entirely on the specific paytable’s house edge and your own risk preference — Pair Plus generally carries a higher house edge than optimal Ante/Play strategy, so it’s a higher-variance, lower-expected-value addition to your session.
Use the calculator’s house-edge output for your specific table’s paytable to make an informed comparison against the base game’s edge before deciding.

Quick question – is the Three Card Poker calculator available for players in Canada? I’m in Ontario and trying to figure out if I can use this tool at OLG-licensed casinos. Also wondering if there are geolocation restrictions or if I’d need a VPN to access the full Gambling Databases platform. Do you guys accept Canadian players on the research side?
Good question. The calculator itself is available to all users globally – it’s a pure math tool with no gambling transactions attached, so there are no licensing blocks on the calculator or research platform. You can use it freely in Ontario. That said, the calculator is designed to work with any Three Card Poker table you encounter, whether at OLG venues or anywhere else, so the strategy remains the same regardless of jurisdiction. The Q-6-4 rule doesn’t change based on geography. If you’re playing at a specific OLG property, just confirm the Pair Plus paytable on the felt before you sit down, since that’s the variable that changes between casinos and affects the side bet’s house edge. No VPN needed for any of our research tools.
