What is a coin flip simulator?
A coin flip simulator is an online tool that randomly returns heads or tails, then summarizes results across one or many flips.
Is an online coin flip random?
This simulator uses the browser's random number generator to choose heads for values below 0.5 and tails for values at or above 0.5.
Can I flip a coin more than once?
Yes. You can simulate any count from 1 to 1,000 flips and review heads, tails, percentages, streaks, and the latest sequence.
What are heads and tails odds?
For a fair coin, heads and tails each have a 50% chance on every individual flip.
Why do repeated flips sometimes look uneven?
Short runs can favor one side by chance. As flip counts increase, the heads and tails percentages usually move closer to 50%.
