Each flip calls JavaScript's Math.random() to generate a number between 0 and 1. Values below 0.5 are heads, the rest are tails — giving each side an equal 50% probability. The tool tracks cumulative totals and computes running percentages by dividing each outcome's count by the total number of flips.
Yes. It uses the browser's built-in pseudorandom number generator (Math.random), which produces a uniform distribution. Each flip has an independent 50/50 chance regardless of previous results.
Small deviations are normal and expected with any random process. The law of large numbers says the ratio converges toward 50% as flips increase, but it doesn't guarantee exact equality at any finite point.
It's fine for casual tie-breaking. For decisions with significant consequences, consider weighing pros and cons rather than relying on randomness.
No. The result is determined instantly by the random number generator. The 0.6-second spin animation is purely visual — the outcome is decided before the animation completes.
Estimate only. Results reflect your inputs and standard formulas. Double-check important decisions independently.
