The Uston SS is a complex, multi-level system for counting cards designed for professional gamblers who already have a deep understanding of card counting. Created by some of the most famous blackjack players in history, the Uston SS Count is a powerful method for eliminating the small house edge in this game and giving players enough of an advantage to generate solid profits over time.

It bears the name of its creator, the legendary player and masterful card counter Ken Uston, who was one of the first people to successfully exploit the concept of team card counting. Uston, who had made millions of dollars from his blackjack skills, was banned from casinos around the world, but this did not stop him from developing and perfecting various strategies for card counting. After introducing the Uston Advanced Plus-Minus and the Uston Advanced Point Count in his book Million Dollar Blackjack, he sought to devise a new system that would be just as strong but without such a high level of complexity.

Eventually, Uston joined forces with other successful blackjack players, Arnold Snyder and Sam Case, and the Uston SS Count was born. It was first published in 1986, and although SS stands for Strongest and Simplest, the system can hardly be described as simple. Many blackjack players, especially those who have only tried basic counts such as the Hi-Lo or the Ace/5 Count, struggle even to understand it. This system was clearly developed with experienced blackjack pros in mind.

Basics of the Uston SS System

At its core, the Uston SS works like any card counting method – it assigns numerical values to each card so that, by keeping a running count, the player can track high versus low cards in the deck. However, this is one of the few level-3 systems, and players should understand that mastering its structure and values will likely take more than a few days. These are the numerical values used in the Uston SS:

  • 2, 3, 4, 6 – +2
  • 5 – +3
  • 7 – +1
  • 8 – 0
  • 9 – -1
  • 10, J, Q, K, A – -2

The imbalance is easy to spot – no card is assigned a -3 to offset the +3 value of the 5s in the deck. In addition, there are four cards worth +2 and five cards worth -2. As a result, the system is unbalanced. You can test this easily – when you count down a single deck, you end up with a final count of +4 rather than 0. Because of this, the starting count is not 0, and this lack of balance actually simplifies the system, as you will see shortly.

As with all unbalanced systems, you do not start counting at 0. In the Uston SS, the initial running count (IRC) depends on the number of decks used in the game; for a single-deck variation the IRC is -4. It reaches -32 for a blackjack game that uses 8 standard decks of cards.

Number of Decks IRC
1 -4
2 -8
4 -16
6 -24
8 -32

This may sound intimidating to those encountering an unbalanced method for the first time, but it actually makes the system more convenient in real-life play. There is no need to convert the running count to a true count – a requirement for balanced systems. The Uston SS remains accurate when you use the IRC values listed above.


How to Use the Uston SS Count?

Despite its name, this is not the easiest card counting method for blackjack. The hardest part is to memorize the numerical values of all cards in the deck and quickly perform mental calculations. The system starts with a freshly shuffled shoe, and players initially place 1-unit or minimum bets ($1, $5, $25, etc.). Let’s take a 6-deck game as an example – the count begins at -24, and as cards are dealt, their respective values are added to the count.

If the following cards appear – 7, Ace, 3, 3, 10, 5, 2, Jack, and 6 – the -24 IRC rises to -18. Because this is still a negative count, players should keep betting the minimum. Once the running count moves above 0, it is time to increase the stakes. The pivot point is +1, which signals that the shoe is rich in high cards (A, 10) and that the odds favor the player. Bets should be raised as the running count climbs (+1, +2, +3, etc.). When the count slips back into negative territory, players should scale down to the minimum wager.

The exact betting spread depends on the player’s experience and bankroll. Naturally, large spreads – such as suddenly betting 32 times the original stake – are obvious tells of card counting. Therefore, counters who prefer aggressive spreads should learn how to disguise their style of play and appear to be recreational blackjack players.

Here is an example of a more conservative 1-5 betting spread, where the maximum wager is 5 times the original bet, or 5 units. In this case, the player would start increasing the bet size at a running count of +2 and try to maintain a safer betting pattern to camouflage their true intentions.

Running Count Betting Units In $
+1 or below 1 $15
+2, +3 2 $30
+4, +5, 3 $45
+6, +7 4 $60
+8 or higher 5 $75

Ken Uston’s Strongest and Simplest system is the easiest, yet an advanced method for counting cards. Although it is a level-3 system, is takes the Aces into account so players are not required to track them separately. More importantly, the Uston SS Count is an unbalanced system and there is no need to estimate the so-called true count. Overall, this is a professional and straightforward system for experienced counters and it works best with basic strategy and a good betting spread.

Obviously, the Uston SS was not intended for beginners. In fact, many blackjack pros would probably find it too complex for actual application in real-life games. Theoretically, the system is easy to understand but keeping a negative count with five different numerical values (+/-1, +/-2, and +3) is quite the challenge. This is why players need a lot of practice before they decide to actually use this method to gain an edge when playing blackjack.

When used correctly, this method not only eliminates the house edge but it also promises a player’s advantage of nearly 2%. The variance with the Uston SS is lower than on a simpler system but players who are confident in their counting skills can improve their odds even more by tracking the Aces. Keeping a side count, whether it is for Aces or for any other type of card, is quite difficult but it is possible.

Moreover, players should know that most of the time, the running count will be negative. So, they will be betting the minimum for a long time. If the count rises from -2 to +3, however, and they place a bet that is several times the amount wagered so far, the casino staff will get suspicious. To avoid that, good counters also apply camouflage betting – something Ken Uston himself was a true master of.

In addition, this method could be applied to various pitch and shoe games. To maximize their profits, players should look for blackjack variations with more favorable rules – 3:2 payout for player blackjack rather than 6:5, dealer stands on all 17s, Surrender allowed, etc.

The Uston SS is an incredibly powerful and accurate system for counting cards in blackjack. However, it is not for those who are just taking their first steps into the world of card counting. This method requires a lot of practice, dedication, and a strong understanding of basic strategy as well as the main principles of card counting.
