Flip once for a quick decision, or up to 100 times in a row to see the distribution (and remember: a 70/30 split across 10 flips is completely normal — coins don't owe you balance). Pick the 'Yes/No' or 'True/False' variants for a clearer answer when you can't remember which side meant what. Runs entirely in your browser.","category":"calc","categoryName":"Calculators","keywords":["flip a coin","coin flip","heads or tails","coin flipper online","random coin flip","virtual coin","online coin toss","coin toss","yes or no flip","true or false flip","fair coin","decision maker","random decision","coin flip generator"],"badge":"Random","url":"https://toptool.io/coin-flip","inputs":[{"type":"number","key":"count","label":"Number of flips","defaultValue":1,"min":1,"max":100,"step":1},{"type":"select","key":"coin","label":"Coin type","defaultValue":"standard","choices":[{"value":"standard","label":"Standard (heads/tails)"},{"value":"yesno","label":"Yes/no"},{"value":"truefalse","label":"True/false"}]}],"outputs":[{"key":"result","label":"Result"},{"key":"results","label":"All flips","multiline":true},{"key":"headsCount","label":"Heads / Yes / True"},{"key":"tailsCount","label":"Tails / No / False"},{"key":"headsPercent","label":"Heads / Yes / True %"}],"invocation":{"webUi":"https://toptool.io/coin-flip","api":null,"notes":"Currently invoked via the web UI at `webUi`.
