Strategy tips

  • Read all four rows: AND-family gates are easiest to separate at 11, while OR-family gates differ clearly at 00.
  • XOR outputs 1 for different inputs; XNOR outputs 1 for matching inputs.
  • Use H or Explain output rule for the exact Boolean rule; arrows move between choices, Space or Enter selects, and keys 1–4 answer directly.
