A fair flip
Each flip uses your browser's cryptographic random generator, so heads and tails each have exactly a 50% chance and every flip is independent of the last. The counts and the longest streak show how runs of the same side happen naturally.
Flipping 100 coins usually gives somewhere between 40 and 60 heads; exactly 50 happens only about 8% of the time. The Space key flips too, and the animation stays gentle when your device asks for reduced motion.
