Coin Flip / Decision Maker
What is Coin Flip?
Coin Flip is a millennia-old decision-making technique that uses chance to resolve dilemmas or choose between options. Our digital version recreates this experience in a practical and accessible way.
By clicking "Flip", a virtual coin is tossed, ensuring a random and fair outcome. It's a perfect tool for quick decisions or when you're torn between two choices.
How It Works
Standard Mode
The classic mode where the coin can land on "Heads" or "Tails". Ideal for simple decisions.
Advanced Mode
Allows you to customize the flip, choosing the number of coins and the type of result (e.g., two heads for "yes").
History of Coin Flip
The use of coins for decision-making dates back to ancient civilizations. In Ancient Rome, for instance, coin tossing was referred to as "navia aut caput".
Besides being a practical method, it was believed that the outcome of the toss was influenced by divine forces, especially in important decisions.
