Red Seven Count

Red Seven is a method of Blackjack card counting that many players use to gain a strategic advantage in blackjack games held in real world casinos. Its creation is attributed to a player called Arnold Snyder, who details both the method and its implementation in a book called Black Belt in Blackjack.

Players should know the big difference between a card counting system and a betting system such as Martingale, as it is often confused.

You need to adjust your expectation of how card counting systems work – if you deploy the Red Seven technique, it’s not a guarantee that you’ll instantly win buckets of money. What it does do, however, is give you a strong indicator of when it might be a good time to make a bet.

The Underlying Principles of the Red Seven Count

As a Blackjack fan, you know that the game judges cards based on their face value. But there are only 52 cards in a deck. If your brain is sufficiently trained, you can memorise the cards you’ve already seen dealt, which allows you to logically deduce what cards remain in the deck. This is the essential concept upon which all card counting strategies are built. They differ only in their methodology.

You see, the ability to literally memorise what cards you’ve seen is a rare skill, and requires an eidetic memory, something very few people have – usually only extremely gifted people or savants have this ability. Card counting systems like Red Seven Count compensate for this by providing an easier way to reach the same statistical conclusions without having to literally specify the remaining cards. Using Red Seven, you may not know which exact cards are still to come, but you can have a good idea of whether they’re high or low.

What the Count Means

You use this data to inform your betting choices. If your card count is telling you that there are a large number of high value cards (10s, Jacks, Queens, Kings and Aces) still to be dealt from the current deck, then you can start to make bigger bets, knowing that it’s likely you’ll either hit Blackjack soon, or at the least hit a hand worth 20, which is difficult for the dealer to beat.

Conversely, if your count is telling you that nearly all of the high value is gone from the deck, you should start to drop your betting down to minimum values. Interestingly, this also becomes a period when it is less risky to hit, since you’re unlikely to draw a card that will bust you.

Specific Implementation

As with other counting systems, the aim is to maintain a running total in your head, which begins at zero. As cards are revealed to you (through dealing), you modify this running total with the following numbers.

For cards valued at 2-6, add 1 to your total. For the 10, the royals and the Ace, subtract one. For all other cards, do nothing, except if you see a Red Seven, in which case, add 1.

The higher your count becomes, the more likely it is that a high value card is imminent. Likewise, the lower it drops, the more likely it is that all high value cards have already been dealt.
