Frequently asked questions

Truly random?
Uses Math.random() - suitable for casual decisions but not cryptographic use.
Why uneven split?
Small sample sizes produce streaks. Over hundreds of flips percentages converge to 50/50.
History persists?
No. Last 20 flips kept in memory only. Cleared on reload.
Why is there a pause before the result?
The coin animates for about nine tenths of a second and the result is recorded when it lands. The outcome is decided before the animation starts, so the wait does not change it.
What do the statistics cover?
Only the flips still in the history list, which holds the last 20. Percentages therefore move a lot and are not a running total of everything you have flipped.
