Coin Flip — Flip a Coin Online

This coin flipper settles decisions the honest way: every toss is drawn from the browser's cryptographic random number generator (crypto.getRandomValues), giving a genuine 50/50 chance that cannot drift or be predicted. The coin spins in a 3D animation and lands on heads or tails right in front of you.

Set the number of coins from 1 to 10 and flip them all with one click — each coin gets its own independent random result. Session counters below the board track heads, tails, the total number of flips, and your current streak, so you can see at a glance how a long run of tosses is going.

Everything happens locally in your browser: no server calls, no accounts, and nothing is stored or tracked. The page keeps working even offline once loaded, which also makes it a handy classroom tool for probability experiments.

Use it to settle who goes first in a game, break a tie, make a quick yes/no decision, or demonstrate that even a fair coin produces surprisingly long streaks over enough flips.
