Coin Flip / Coin Flipper
Flip a virtual coin online - Heads or Tails decision maker with flip history and statistics
[ Coin Flip - Quick Summary ]
What: Virtual coin flipper that generates random heads or tails results using cryptographically secure randomization.
When to use: Quick binary decisions, determining first player in games, settling debates, teaching probability, or any 50/50 choice scenario.
Example: Flip coin → HEADS (or flip 5 coins → [H, T, H, H, T] → 3 heads, 2 tails)
Important: Each flip has exactly 50% probability for heads and 50% for tails. Supports multiple simultaneous flips (1-100) and Best of N options. Uses CSPRNG for true randomness.

Technical Details: How We Generate Coin Flips
Our coin flipper uses cryptographically secure random number generation (CSPRNG) to simulate a fair coin toss. Each flip generates a random integer in the range [0, 1] where 0 represents HEADS and 1 represents TAILS. This ensures exactly 50% probability for each outcome, matching the behavior of a physical coin.
// Coin flip algorithm Algorithm: Cryptographically Secure Random Binary Choice For each flip: 1. Generate random integer in range [0, 1] 2. Map result: 0 = HEADS, 1 = TAILS 3. Return outcome Probability: P(HEADS) = 0.5 (50%) P(TAILS) = 0.5 (50%) For "Best of N" flips: 1. Perform N individual flips 2. Count occurrences of each outcome 3. Winner = outcome with majority count
