Build a real edge at the blackjack table. Five counting systems, drills that match casino pace, and a counter-friendliness rating for every major US casino.
Deck Counter is a serious card counting trainer for blackjack. No gimmicks, no casino games — just the tools you need to build a real edge at the table.
TRAIN YOUR COUNT
Deal through a full shoe and track the running count. Teaching mode shows the count value of every card as it's dealt. Once you have the basics, switch to Blind mode to test yourself: count silently for a set number of cards, then enter your running count to see how close you are. Speed mode auto-advances cards at adjustable intervals to simulate real casino pace.
FIVE COUNTING SYSTEMS
Deck Counter supports the five most widely used counting strategies:
• Hi-Lo — the standard beginner system (free)
• KO (Knock-Out) — unbalanced, no true count required (Pro)
• Hi-Opt I — intermediate balanced system (Pro)
• Hi-Opt II — advanced, higher accuracy (Pro)
• Zen Count — intermediate balanced with extra precision (Pro)
DRILL MODES
Three targeted drills to sharpen specific skills:
• True Count Drill — enter the true count from a given running count and deck depth
• Speed Drill — auto-advance cards to build count speed under pressure
• Running Count Quiz — deal a batch of cards, then recall the count from memory
STRATEGY CHARTS
Full basic strategy reference charts for both H17 and S17 rule sets. Color-coded by action: Stand, Hit, Double, Split, Surrender. Scroll both axes to see every hand combination.
CASINO FINDER
A curated directory of ~30 major US casinos rated on counter-friendliness (1–10). Scored on deck count, payout (3:2 vs 6:5), dealer rules, surrender availability, and penetration depth. Sort by distance from your current location, by score, or alphabetically. Each casino shows the best available game and full rule breakdown.
SESSION HISTORY
Every session is recorded. Your home screen tracks lifetime accuracy, total cards dealt, and your current accuracy streak (consecutive sessions at 80%+). Recent sessions display in a table with strategy, rule set, and result.
FULLY OFFLINE
Deck Counter works without an internet connection. Your training data, settings, and history stay on your device. No account required, no tracking, no ads.
