FAQ

• Is the coin flip truly 50% random?

  Yes. Every toss uses a cryptographically uniform random generator with an exact 50% chance for Heads and 50% for Tails. Each toss is completely independent of past flips.

• Can past flips predict future flips?

  No. Mathematicians call this the Gambler Fallacy. Even if the coin lands on Heads ten times in a row, the probability that the next flip lands on Heads remains exactly 50%.

• How does the global leaderboard determine my rank?

  Your highest streak of correct calls determines your position. The leaderboard matches the real geometric distribution of coin flip probabilities so you can view your rank among thousands of global players.

• What are the odds to reach a streak of 10?

  The odds to score 10 consecutive correct calls are 1 in 1,024, which equals 0.0976%. A streak of 10 places you in the top tenth of one percent of all players.
