The Hi-Lo practice lab
See the count change.
Add cards and see how the running count and true count are calculated.
Example starts at a running count of 0.
+2 ÷ 4.0 = +0.50
True count = running count ÷ estimated decks remaining.
Practice cards are not a finite shoe simulation. Decks remaining is your manual estimate. Only the most recent eight cards are displayed; the count includes all added cards.
How the Hi-Lo count works
Assign a value
In Hi-Lo, cards 2–6 count +1, 7–9 count 0, and 10, J, Q, K and A count −1.
Keep a running count
Add each card’s value to a running total as cards are seen. A fresh count starts at 0.
Adjust for decks remaining
Divide the running count by the estimated decks remaining to obtain the true count.
