The Red 7 Card Counting System

The Red 7 System is a powerful system for counting cards in blackjack and is considered to be the most effective method for the level of simplicity it offers. It is an unbalanced, level-1 system that is often compared to the classic Hi-Lo count but it is even easier to implement without mistakes even for beginners.

The Red Seven or Red 7 method was devised by one of the most famous card counters in history, Arnold Snyder who described it in his 1983 book Blackbelt in Blackjack. Snyder, who also invented the Zen Count, created the Red 7 to eliminate the need to convert the running count into a true count. As a result, this method is clean, simple, and easy to use, while at the same time, it is profitable when applied perfectly and in combination with basic strategy, proper bankroll, and a relatively aggressive betting spread.

Blackjack players who decide to use this system to count cards will have only a couple of things to remember before testing their counting skills in real casinos.

Advantages and Disadvantages of the Red 7 System


The main advantage of using the Red 7 System is that it can be learned within a few hours and applied successfully in real-money games even by beginner-level counters. It is a level-1 system where players only add or subtract 1 from the running count. The method does not require a side count for Aces, 10s or any other card to be kept, although the color of the 7s should be taken into account.

Although the system is quite simple, compared to other professional methods for counting cards in blackjack, it features a few details that could confuse and intimidate beginner-level counters. The first thing is that they need to focus on the color of the 7s, which may sound easy but in a noisy, crowded casino and a table where the cards are dealt really quickly, this could be a daunting task.

At the same time, the Red 7 count is very efficient in signaling the player when to raise his bets. This system allows players to make changes to the basic strategy when the odds are in their favor. In addition, it is suitable for both amateurs and blackjack pros, as well as for shoe and pitch games.

The need to always know the initial running count of the game could also be frustrating for less experienced players. Besides, some people simply do not feel comfortable dealing with negative numbers. But with this system, the count will remain negative for most of the time. Some players would also probably question whether deviating from the basic strategy is a good idea. In certain cases, it is, and with only a few changes to it, players can increase their advantage even more.

Just like all card counting systems, the Red 7 System has its strengths and weaknesses that should be considered before using it in a real, live blackjack game. This is a wonderful method that even recreational players can try, although to be effective, it should be used with no mistakes and after practicing it for some time. Overall, Snyder’s Red 7 card counting system is relatively easy, safe in real-money games, and profitable with a large bankroll and medium betting spread (1-10 or 1-15).
