Fair Coin Probability
Each flip has exactly 50% chance for heads or tails. Over many flips, the results should approach 50/50 distribution.
Flipping a coin is the fastest way to settle a 50/50 decision, but a physical coin is not always within reach, and typing "random number 1 or 2" into a search bar feels like a cop-out. This coin flipper solves that by simulating a real coin toss right in the browser, complete with a spinning animation that mimics the arc and tumble of an actual coin before it settles on heads or tails. It works for anything a real coin would: picking who goes first in a game, breaking a tie between two restaurant choices, running a quick classroom demo of probability, or just deciding whether to take the stairs or the elevator.
Using it is as simple as tapping the coin — the animation plays out, the coin lands, and the result (heads or tails) is shown immediately, so there's no ambiguity about the outcome the way a coin rolling under the couch can cause. Every flip is logged to a running history, so you can scroll back and see the exact sequence of results from the current session, which is handy if you're settling a best-of-five with a friend or just curious whether you're on a heads streak. Alongside the history, the tool keeps live stats — tallying how many times heads and tails have come up and what percentage each represents — so you can see at a glance how close the results are tracking to a true 50/50 split.
Because every flip is generated and rendered entirely on your device, there's nothing to upload and nothing to sign up for — you can flip as many times as you want without the tool sending anything to a server. That also makes it a fun, low-stakes way to illustrate the law of large numbers: flip a handful of times and the ratio might look skewed, but keep going and watch the heads/tails percentages in the stats panel drift back toward even.
