Progress through five tiers, from the Hi-Lo foundations to realistic distractions.
Recognize +1, 0 and −1, then keep the count through a multi-deck shoe.
Choose Tutorial, Easy or Standard and work at your own pace.
No real-money play, bets or payouts. Practice observation and arithmetic.
Add +1 for every 2 through 6, −1 for every 10 through Ace, and 0 for 7s, 8s, and 9s. The running total — your running count — tracks how rich the remaining shoe is in high cards. A high count is your edge.
