About this tool
Each flip is an independent, uniformly random 50/50 draw via Math.random() — previous flips have no influence on the next one, even after a long streak of the same result (the "gambler's fallacy" is exactly the mistaken belief that they would). The tally and recent-flips list persist as you keep flipping, so you can watch the heads/tails ratio settle closer to 50/50 the more flips you make.
