The Hi-Lo count
Hi-Lo is a simple counting system. Every card seen changes a running count: +1 for 2 to 6, 0 for 7 to 9, and −1 for tens and aces. A positive count means the remaining cards are richer in tens and aces. To compare shoes of different sizes, counters divide the running count by the decks left to get a true count.
How the exercise works
- Choose a speed and a number of cards, then press Start.
- Keep the count in your head. When the cards finish, type your count and press Check my count.
- After checking, review the card list: each card shows the value it added.
- Switch to True count or change the speed to see how the task changes.
What it shows about counting
Keeping the count is only one part of what real counting would involve. Counting does not guarantee any advantage and gives no assurance of profit, and it does not apply to games that reshuffle every hand. For the full picture, see card counting for beginners.
This page is a mental exercise with simulated cards only. It is not preparation for real-money play and makes no promise of any result.
