## 21Counts Description
Learn to count cards like a pro — five minutes at a time.

21 Counts is a Duolingo-style trainer for blackjack card counting. Your guide is Bandit, a friendly raccoon teacher who takes you from the basics of the Hi-Lo system all the way to counting under real casino conditions: busy tables, dealer chatter, mid-shoe shuffles, and pit-boss heat.

WHAT'S INSIDE
• 100 short, focused lessons across five tiers
• Tier 1 — Foundations: map every card to +1, 0, or −1 instantly
• Tier 2 — Running Count: hold the count across a full multi-deck shoe at table speed
• Tier 3 — Basic Strategy: every play decision before the count bends it
• Tier 4 — True Count & Betting: convert RC to TC, bet to the count, deviate on the plays that matter
• Tier 5 — Casino Conditions: distractions, mid-shoe shuffles, pit boss heat, camouflage
• A timed exam between tiers — prove you've got it before the next tier unlocks

THE SHOE
Open-ended practice. Pick Tutorial, Easy, or Standard and count a real shoe at your own pace. Standard runs at table speed with chatter overlays so you can count through the noise — exactly what you'll face at a real table.

WHO IT'S FOR
• Casino visitors who want a real mathematical edge, not just luck
• Strategy and math enthusiasts who love a clean, learnable system
• Anyone curious how the math behind the table actually works
• People who watched 21 and wondered what those kids were really doing

NOT A GAMBLING APP
21 Counts is an education product. There's no real-money play, no bets, no payouts, no in-app casino. Cards in drills are educational visuals; you call a count, not a wager. The skill it teaches is observation and arithmetic — both legal and entirely on the player.

21 COUNTS PRO
Unlock with a 7-day free trial:
• All Tiers 3–5 (Basic Strategy, True Count, Casino Conditions)
• Standard Shoe with full distraction overlays
• Detailed stats and progress history
• All future curriculum (Graduate Tier coming)

Available as Monthly, Yearly (best value), or one-time Lifetime purchase. Cancel anytime from the App Store.
