Coin Flip

Yes. The flip uses Math.random() which is based on a pseudo-random number generator (PRNG) seeded by the browser. It is random enough for all practical everyday decisions — the probability of heads vs tails is 50/50 for each independent flip.

No. Each coin flip is completely independent. Getting 10 heads in a row does not make tails more likely on the next flip. This is called the Gambler’s Fallacy — a coin has no memory.

The probability is (0.5)^10 = 1 in 1,024 (about 0.098%). It is unlikely but not impossible. With enough flips, any streak will eventually occur.

Absolutely. Virtual coin flips are used for sports starting decisions, game tie-breaking, choosing between two equally appealing options, settling friendly debates, and any situation requiring a fair random choice between two outcomes.

Interestingly, research by Stanford professor Persi Diaconis found that real coins land on the same side they started from about 51% of the time due to physics (a slight wobble during the flip). Virtual coin flips are perfectly 50/50.
