    EV per Hour -$51.20
    ⚠️ House edge. Minimum bet or wong out.

    Edge by True Count

    How it works

    • Base edge comes from casino rules (house edge)
    • Each true count point is worth ~0.5% to the player
    • At TC +2, you typically have a positive edge
    • Spread your bets higher when you have the edge
