*Perfect Blackjack Chart
*Blackjack Strategy Chart
As an approximation each point increase in the True Count shifts the House Edge 0.5% towards the player. I stress that this is not a precise figure and as the player who plays perfect Basic Strategy is generally starting with a disadvantage of around 0.5% or a little more, but this is just an approximation and vary with many different factors. If you want to lower that edge, then your best bet are the different blackjack charts found below. The house edge in Blackjack is 8%. If you’re an active player that number will add up over time. The best (and only correct) mathematical strategy for achieving optimal play is to use a blackjack chart.
Perfect Pairs blackjack plays almost exactly like a regulargame of 21. The big difference is the “perfect pairs” side bet,which offers the opportunity to win a large jackpot. As withmost side bets with large payouts, the house edge is higher thanyou’re probably prepared for.
The purpose of this page is to explain how to play PerfectPairs blackjack, what the house edge is for both the main gameand for the optional side bet, and the correct basic strategy tofollow while playing.How to Play
The rules for playing Perfect Pairs are the same as astandard game. You get two cards. The dealer gets two cards. Youget to hit, stand, double down, etc. You bust if you go over 21,and the dealer does too.
The only difference is the side bet. This bet is won or lostseparately from your main bet.
You win the main bet by either getting closer to 21 than thedealer or still being in the hand when the dealer busts.
You win the perfect pairs bet by getting a pair. That soundseasy enough, but the payout is based on how good your pair is.
Here’s a typical payout table:
*Different colors and different suits: 5 to 1
*Same color but different suits: 10 to 1
*Same color and same suit (the eponymous perfect pair):30 to 1
Of course, different casinos will have different payouts. Youmight only see 25 to 1 in some casinos for a perfect pair, butanother, more generous property might offer a 35 to 1 payout.The amounts can vary for the other combinations, too. You mightsee 6 to 1 or 12 to 1 payouts instead of 5 to 1 and 10 to 1.
Casinos are experts at manipulating the payouts for somehands in order to adjust the house edge accordingly. They’llcompare how many people play at one set of payouts with how muchthey’re projected to earn, and they optimize accordingly. Theywant the most action with the highest edge. Adjusting thepayouts for the side bets is one way they can accomplish this.The House Edge
The house edge for the perfect pairs side bet hovers between2% or and 11%.
You’ll only see a perfect pair come up once in about every 60hands on average. Depending on what kind of luck you’re having,you might see it come up a little more often or a lot lessoften, but the frequency should hover right around thosenumbers.
The house edge for blackjack is hard to calculate, as it’sbased on a large number of situations.
But calculating the house edge for this individual side betisn’t hard at all.
You start by calculating the odds of getting each hand andcomparing that with the payout for each hand.
We’ll assume that you’re playing in a game with 8 decks forpurposes of this example.
For the top payout of 30 to 1, you have to calculate the oddsof being dealt a 2nd card that’s the same rank and suit as yourfirst card. With 8 decks in play, you have 416 cards total, butone of those has already been dealt. That leaves 415 cards, butonly 7 of them will make your hand. So the probability ofgetting a “perfect pair” is 7/415, or about 1 in 59.
*That’s a 1.69% chance of winning 30 units.
For same color but different suits, we use a similarcalculation. You have 415 cards, and 8 cards which will makeyour hand. The probability of making this hand is 8/415, orabout 1 in 51.
*That’s a 1.93% chance of winning 10 units.
For the lowest paying hand, which is a pair of differentcolors and different suits, we use another similar calculation.You still have 415 cards, but you still only have 16 cards whichwill make your hand. (Some of these cards will make a higherpaying hand, so they don’t factor into the calculation.) Theprobability of making this hand is the same as before, 16/415,or about 1 in 26.
*That’s a 3.86% chance of winning 5 units.
The expected value of each of those payouts can be calculatedby multiplying the percentage chance of hitting the hand by thepayout, as follows:
*1.69% X 30 = 0.507
*1.93% X 10 = 0.193
*3.86% X 5 = 0.193
When you add those 3 possibilities together, you get thepayback percentage for the bet.
*0.507 + 0.193 + 0.193 = 89.3%.
*Subtract that from 100%, and your house edge is 10.7%.
A casino which offers a higher payout on these hands wouldoffer a lower house edge. And changing the number of decks wouldalso affect the payout percentage, for obvious reasons.
Here’s an example of how changing the payout on a hand wouldchange the house edge:
Suppose you got 35 to 1 instead of 30 to 1. That would changethe expected value on that payout from 0.507 to 0.5915. That’s ahuge difference of about 9%, which would decrease the house edgeto 1.7%, making this a much more reasonable bet.
Here’s an example of how changing the number of decks in playwould change the house edge:
Suppose you have 6 decks in play instead of 8. Instead of a7/415 chance of hitting your hand, you now have a 5/306 chanceof hitting your hand. That’s a 1.63% chance of hitting the toppaying hand, instead of 1.69%. So the house edge on this sidebet would actually go up with fewer decks in play.A Simple Strategy for the Perfect Pairs Bet
Be advised that this strategy does nothing to eliminate orreduce the house edge. It’s just a fun way to take advantage ofthe perfect pairs side bet without losing too much money andstill having a chance to hit one of those big payouts.
The idea is to set aside a separate bankroll of betting unitsequal to the payout for a perfect pair.Example
If you’re playing in a casino that offers a 25 to 1 payoutfor a perfect pair, and you’re playing for $5 per hand, setaside $125 for the perfect pair bet. (That’s $5 times 25.)Perfect Blackjack Chart
Use that $125 to bet $5 each hand on the perfect pair sidebet until you run out of bankroll or until you hit a perfectpair and get your 25 to 1 payout.
There’s a reasonable chance you’ll hit a perfect pair at somepoint between 1 and 60 hands. If you hit it during the first 25hands, you’ll have generated a profit, possibly a large one. Ifyou don’t hit a perfect pair, you’ve only lost $125.
Play your regular blackjack hand as normal, as if you didn’thave any money put on the perfect pair bet. You’ll usestandard basic strategy to play your normal blackjack hand.Depending on the other rules variations, you’ll be facing ahouse edge of around 1%, maybe less.Summary
Perfect Pairs Blackjack is a fun little variant with aninteresting side bet with a relatively high house edge. But thehouse edge on this bet isn’t much higher than the house edge ongames with comparable high payout bets like roulette—in fact, insome cases you might even be able to face a slightly lower houseedge than in roulette. It all depends on how much the payoutsare for the various hands.
A simple money management technique that enables you take ashot at this big payout without risking a huge amount of moneyinvolves setting aside a separate bankroll specifically for thatside bet. By making that amount the equivalent of the payout forthe perfect pairs bet, you give yourself a reasonable chance athitting this min-jackpot before you run out of money. The sooneryou get lucky, the more you’ll profit.Blackjack Strategy Chart
But as with any negative expectation bet, you’re going to seemore losses than wins in the long run. Money managementtechniques can’t chance the odds of a game, and Perfect Pairsblackjack is no exception to this rule of thumb.
