    THE FIELD GUIDE

    Two variables. One magic number.

    You and Byte begin at zero with A and B. Reach exactly 42 on either variable to win immediately. Going over is allowed; subtract your way back.

    One turn = draw two, play two.

    Cards are drawn automatically. Choose a card, then click a variable to play it. Values and loops can go on either board. Attacks target Byte; defenses usually target you. You may discard instead. After two instructions, choose End turn. Byte then plays.

    Read the code

    When the deck runs out, the player who drew its last cards finishes that turn. Whoever has a variable closest to 42 wins; equal distances draw.

    This core-duel edition

    A local two-player adaptation with a computer rival. It retains 93 cards from the upstream CSV and omits the seven bonus types. The player-count loop is ×2. For clear digital rules: Firewall is a proactive one-use shield; Refactoring removes both restrictions; Rollback restores the preceding board state. The computer sees only its own hand. Undo and a guided combo are optional practice aids. This is not the complete printable multiplayer game.

    Keyboard: 1–8 selects a card; Q/W target your A/B; O/P target Byte’s A/B; D discards; U undoes; Enter ends a completed turn. You can also Tab through every control. Progress and duels stay on your device.
