Frequently Asked Questions
How does the online coin flip work?+
Our coin flip uses a cryptographically random number generator — Math.random() — which produces a fair, unbiased result every time. It is statistically equivalent to flipping a real physical coin, with exactly a 50% chance of heads (Sun) and 50% chance of tails (Moon).
Is the coin flip truly random?+
Yes. Each flip is completely independent. No matter how many times you flip, the probability resets to exactly 50/50 each time — this is known as being "memoryless." Prior outcomes never influence the next result.
What does Heads vs Tails mean in the Cosmic Coin Flip?+
We map Heads to the Sun ☀️ (a "Yes" answer) and Tails to the Moon 🌙 (a "No" answer), drawing from ancient solar and lunar symbolism used in astrology and divination. The Sun represents action, clarity, and affirmation. The Moon represents reflection, pause, and reconsideration.
When should I use a coin flip to make a decision?+
A coin flip is ideal for simple binary decisions where both outcomes are acceptable — choosing between two restaurants, settling a friendly dispute, deciding who goes first in a game, or breaking a deadlock in group decisions. For major life decisions, consider pairing it with our Yes/No Tarot for deeper insight.
Can I use this for board games or tabletop games?+
Absolutely. Our virtual coin flip is perfect as a game randomizer when you don't have a physical coin handy. Use it for games like Monopoly, war, poker, or any game requiring a fair coin toss.
