F7 — BlackJack Card Rules

The rules written properly. The charts laid out clearly. Drill them until they are automatic.

F7 - BlackJack Card Rules is a reference and practice companion for the classic twenty-one card game — the rules written properly, the decision charts laid out clearly, and a set of card tools to drill them until they are automatic. This is an educational reference and a memory drill: nothing is for sale, there is nothing to purchase and nothing to win. It is for people who want to understand why the chart says what it says.

What you get

Inside the app

  • Lesson library

    Short, structured lessons that take you from card values to hard and soft hands, pairs, splitting and doubling — one idea at a time.

  • Rules reference

    The full rule set in plain English, including dealer rules, hand resolution and the common table variations.

  • Card values

    A clean table showing how every card counts, including the flexible ace.

  • Decision chart

    The complete hit, stand, split and double chart — colour-coded and readable on a phone screen instead of a smudged printout.

  • Dealer bust reference

    How often a dealer busts from each upcard, so the chart stops feeling arbitrary.

  • Quiz mode

    Random hands dealt at you, the correct decision revealed with the reasoning, and a running score so you can see where your gaps are.

  • Card toolbox

    Shuffle a deck, cut it, draw single cards and run a red-or-black exercise, all with realistic playing-card graphics.

  • Notebook

    Write down the rules you keep forgetting and the patterns you spot.
