Coin Flip

The coin flip is the oldest tie-breaker there is: two outcomes, equal odds, no arguing. This page gives you a virtual coin you can flip anywhere, even when there is no physical coin in your pocket. Tap once, watch the coin spin, and get a clear heads or tails result you can act on immediately.

Each flip is generated by a random number generator that assigns exactly 50% probability to each side. A physical coin can be affected by its weight distribution, the flipping technique, or the surface it lands on. A digital coin has none of those quirks, and it can never roll under the sofa or land on its edge.

Use it whenever a decision has exactly two options and neither one is clearly better. Because the outcome is out of your hands, a coin flip also works as a gut check: if you catch yourself hoping for heads while the coin is still spinning, you already know your answer.
