The Mechanics of the Hi-Lo Count
Counters do not memorize every single card played; instead, they assign a simple value to groups of cards.

| Card Value | Hi-Lo Value | Reasoning |
|---|---|---|
| 2, 3, 4, 5, 6 | +1 | Removes bad cards from the remaining deck |
| 7, 8, 9 | 0 (Neutral) | Does not significantly impact player advantage |
