Coin Flip

Yes. Each flip is determined by Math.random(), giving heads and tails an equal 50% probability.

Yes — just click Flip Coin again. Your last 10 flips are shown in the history below the coin.

The probability of getting heads 10 times in a row is (0.5)^10 = 1/1024, or about 0.1%. Each flip is independent — past results don't affect future flips.

Yes. Once the page is loaded, the coin flip works 100% offline.

Yes. The result is determined by JavaScript's Math.random() function before the animation plays, giving heads and tails an exactly equal 50% probability on every flip.

The standard coin flip tool flips one coin at a time. If you need multiple independent results simultaneously, flip several times in sequence — each result is independent of the last.

A physical coin can be slightly biased by weight distribution, tossing technique, or surface texture. A digital coin flip uses a mathematically uniform random function, making it as fair as any tool can be. It is also always available, even when you don't have a coin handy.

Yes. Both outcomes have exactly 50% probability on every flip, making it a perfectly fair way to resolve a two-option decision. It is widely used for settling disputes, choosing who goes first in a game, or making quick binary choices.

Yes — many sports use a coin toss to decide starting positions, first serve, or field side. A digital coin flip is just as valid as a physical one for informal matches and practice games.

The flip uses JavaScript's built-in Math.random() function, which generates a pseudo-random floating-point number between 0 and 1. If the result is below 0.5 it is heads; 0.5 or above is tails. This gives both outcomes an equal 50% chance.
