What is the Gambler’s Fallacy in coin flips?

The Gambler’s Fallacy is the mistaken belief that past flips influence future flips. Even if you flip Heads 10 times in a row, the 11th flip still has an exact 50% chance of being Heads and 50% chance of Tails.

Can I play Best of 3 (Bo3) or Best of 5 (Bo5)?

Yes! Use the built-in Best-of-3 and Best-of-5 tournament modes. The tool automatically tracks rounds, displays the score, and crowns the ultimate champion with celebratory confetti.

What is the probability of flipping 10 Heads in a row?

The mathematical probability of flipping 10 consecutive Heads is (1/2)^10, which equals 1 in 1,024 (or approximately 0.0977%). You can test this using our instant 100-flip simulation mode!

Can I customize the coin faces for personal decisions?

Yes! You can switch from Heads/Tails to Yes/No, or type custom labels like "Pizza vs Burger", "Option A vs Option B", or team names for sports matches.

Can I flip multiple coins at once?

Yes, you can toss 1, 2, 3, or 4 coins simultaneously to quickly settle multi-person decisions or calculate joint binomial probability.
