KardShark

KardShark is a fun, cozy way to actually learn how to count cards in blackjack —
not just read about it.

You'll master the Hi-Lo counting system one bite-sized level at a time, and the
speed ramps up as you improve:

• Learn the tags — tap whether each card is +1, 0, or −1
• Keep a running count as cards appear
• Speed drills — cards flash faster and faster; report the final count
• Take the observer's seat — a full hand is dealt and played out; count every card
• Sit down and play — bet to the count, play the hand with perfect basic

strategy, and keep counting to the end

PRACTICE THAT STICKS

• 9 levels with a clear difficulty and speed progression
• Stars, XP, and unlockable levels
• Achievements and a trophy shelf
• A Daily Challenge with streaks — a new five-round gauntlet every day
• Coach mode shows the count tag on each card while you learn, then turn it off
• A built-in cheat sheet: the Hi-Lo tags, the true-count bet ramp, and a full

basic-strategy chart

COZY, POLISHED, OFFLINE

• A warm lo-fi cat-café aesthetic with a reactive dealer cat
• Optional chill background music and sound
• Full keyboard support and a clean, accessible UI
• Works offline — no account, no sign-up, nothing to track

KardShark is for entertainment and education. It teaches a legal advantage-play
