A strategy for tracking the ratio of high to low cards remaining in the deck to gain an edge.
Card counting is an advantage play technique in blackjack where you track whether the remaining deck is rich in high cards (10s, face cards, Aces) or low cards. When the remaining deck has proportionally more high cards, the player has an edge.
The most common system is Hi-Lo: cards 2-6 are +1, cards 7-9 are 0, and cards 10-A are -1. You keep a running count, convert to true count (dividing by decks remaining), and increase your bets when the count is positive.
Card counting is legal but casinos can ban you for it. It's not easy — it requires intense concentration, discipline to avoid detection, and enough bankroll to weather significant variance. The edge from counting is typically 0.5-1.5%.
Using the Hi-Lo system, a counter at a 6-deck Caesars Palace table adds +1 for every 2-6 dealt and -1 for every 10-Ace. With 4 decks left and a running count of +8, the true count is +2, signaling a deck rich in tens and aces.
The player then raises their bet from a $25 baseline to $150 (a 1-6 spread), capturing roughly a 1% edge when the count is positive. At 80 hands per hour, a counter with a $10,000 bankroll expects to earn $15-25 per hour on average — real money, but dwarfed by the variance. Casinos backoff suspected counters by shuffling early, flat-betting them, or barring play, so disguise and bankroll discipline matter as much as the math.
