TAILS

How It Works

Our coin flipper uses JavaScript's cryptographically secure random number generator to ensure truly random results. Each flip has exactly a 50% chance of landing on heads or tails.

Common Uses

  • Decision Making: Can't decide between two options? Let the coin decide!
  • Games: Start games, determine who goes first, or settle disputes
  • Sports: Coin toss to decide which team kicks off or chooses sides
  • Probability Learning: Demonstrate randomness and probability concepts
  • Fun Challenges: Create coin flip challenges or betting games with friends

Is It Really Random?

Yes! We use crypto.getRandomValues() when available, which is a cryptographically secure random number generator. This ensures that each flip is truly unpredictable and has an equal 50/50 chance of being heads or tails.
