How to Play "Lie Detector" Card Game? (Likely Truth or Dare or Bulls & Cows)

There is no widely known card game called exactly "Lie Detector." You're likely thinking of one of these two games:

1. Truth or Dare (Party Game)

• Players: 2+
• Goal: Fun, embarrassment, getting to know each other.
• Play: Players choose "Truth" (answer a question honestly) or "Dare" (perform a challenge). No cards required, though card decks with prompts exist.

2. Bulls and Cows (a.k.a. "Guess the Number," "Code Breaker," "Mastermind" with numbers)

• Players: 2
• Goal: Deduce a secret 4-digit number (no repeating digits) using logic.
• Play:
  1. One player sets a secret 4-digit code (digits 0-9, no repeats).
  2. Other guesses a 4-digit number.
  3. Setter gives feedback: Bulls = correct digit in correct position; Cows = correct digit in wrong position.
  4. Repeat until code is cracked.

If neither matches, please provide details: Number of players, deck type, goal, rough rules. That will help identify the game!
