Card counting is mental arithmetic: add or subtract a value for every card you see. Start at zero.
Example: 3 → K → 7 → 5 means +1 −1 +0 +1 = +1. Keep that total in your head as more cards appear. It does not reset between questions; it resets only when a new deck starts.
Multiple decks: A shoe is several shuffled decks together. The Hi-Lo card values stay exactly the same. Keep one running total across the entire shoe — don't reset after each question.
To estimate decks remaining, watch how many cards have been dealt. One deck is 52 cards. In a six-deck shoe, after 104 cards, approximately 4 decks remain. Real players usually estimate to the nearest half-deck.
True count = running count ÷ decks remaining. This adjusts the count for how concentrated the remaining high and low cards are.
Expert mode asks for the true count rounded to one decimal place. This game uses the estimated remaining decks to the nearest half deck (minimum 0.5 deck).
Scoring: In Normal and Hard, choose positive or negative for 1 point, or type the exact count for 5. If the count is zero, type 0. In Expert, divide the running count by the estimated decks remaining and round to one decimal place (the true count).
