Count Dojo is the first app that actually teaches card counting — from complete beginner to casino-ready advantage player — through a structured, gamified curriculum. Every other card counting app assumes you already know what to practice. Count Dojo assumes you know nothing and guides you step by step, the way Duolingo does for languages. For players who already know the game, the calculators, casino database, and results tracker are built for real sessions. WHAT YOU'LL LEARN - Complete basic strategy — hard totals, soft totals, pairs, surrender - The Hi-Lo system used by professional advantage players - Running count, true count conversion, mental math - Bet sizing and bankroll management (Kelly Criterion) - The Illustrious 18 deviations and Fab 4 surrenders - Cover play and heat management - Game selection — finding beatable tables - Advanced topics: hole carding, side bets, team play HOW IT WORKS A Duolingo-style skill tree with 6 units and 100+ bite-sized lessons. Clear explanations, real math, and quiz questions. Side branches cover history, theory, and advanced concepts. PRACTICE DRILLS - Flashcard — cement basic strategy reflexes - Running count — slow, medium, and fast speeds - Deck countdown timer — hit pro speed (under 30s) - True count conversion - Bet sizing with realistic chips - Deviations — easy, medium, and hard difficulty - Integrated Simulator — all skills at once, graded - Personalized review — drills your weak spots automatically FULL CASINO SIMULATOR A realistic blackjack session with AI players, pit-boss conversations, heat events, insurance, distractions, and A+ grading across basic strategy, counting, bet sizing, and deviations. Every hand logged for post-session analysis. PRO TOOLS - Edge Calculator — house edge, sensitivity curves, penetration analysis - Bankroll Planner — solve for required bankroll or risk of ruin, custom bet ramps, 2-hand support, wonging, variance projection - Casino Database — 842+ real venues with rules, house edge, penetration, AP flags, and community intel - Results Tracker — log real sessions, track multiple bankrolls, watch expected vs actual on a cumulative chart BUILT FOR REAL PLAYERS Created by an experienced advantage player. Every chart, EV calculation, and deviation index is verified against Wizard of Odds, Stanford Wong, and Don Schlesinger. Includes 48 basic strategy charts covering every common rule variation. GAMIFICATION XP across 20 belt levels, 72 achievements, daily streaks with optional practice reminders, medals per drill (bronze / silver / gold / legend), cloud sync, and light/dark themes.
