Heads or tails in one tap — with a running tally, streaks, best-of matches and 100-flip stats
No flips yet — tap the coin
The face is decided the instant you flip. The animation only plays it back.

Which side is heads: real coins disagree about this, so this page settles it — the face struck with H is heads, the other one is tails. The coin art is an invented design and does not copy any real currency. Renaming the sides only changes the words on screen; the physical face stays the same.
When the result is decided: the face is produced in your own browser the instant you flip, and it is written to your local record before the animation even starts. Refreshing the page, backgrounding the tab or turning the animation off cannot change a flip that already happened — you cannot reload your way to a nicer answer. Every flip is 50/50, nothing is sent to a server, and there is no probability slider anywhere on the page.
Three modes: Flip is the default, one throw at a time, and can be switched to 10 or 100 flips at once to see the split and the longest run in that batch. Best of gives you 3, 5 or 7 rounds and stops the moment one side reaches (N+1)/2 wins — 2-0 in a best of three ends it there. Call it is a fixed ten calls where you predict before every throw and get your score, your longest run of correct calls and the real odds at the end. Every flip from every mode feeds the same running tally.
Tally and streaks: the stat line always shows Heads X : Tails Y and the total. A streak counter is added only once the same side has landed at least twice in a row. Streaks carry across modes, across refreshes and across days — only Clear my data in Settings resets them. Longest streak ever, total flips and best call score are the only three things this game asks you to beat.
How common a streak really is: starting from any flip, three of the same side in a row happens 1 time in 4, four in a row 1 in 8, five 1 in 16, six 1 in 32 and eight 1 in 128. Over 100 flips a run of five or six is close to routine, and it says nothing about the coin. Past results never move the next one — it is still 50/50.
House rules and variants: say out loud what each side means before you flip, not after. For a two-person call, one phone held up is enough — there is no hidden information, so nothing needs passing around. The old rule of flipping all three rounds and taking whichever side shows up twice gives exactly the same winner as stopping at 2-0, which is why this page saves you the flip. If someone wants a rematch, agree on the number of rounds first, or you will keep flipping until one of you is happy. In a classroom, run three batches of 100 and let people watch the split walk back toward 50%.
There is no technique: 50/50 cannot be trained, so any trick that claims to raise your hit rate is the gambler's fallacy, and this page will never tell you that your intuition beat some invented percentage of players. Three things do help: define the sides before you flip, agree the match length before you start, and pay attention to your own first reaction when it lands — that usually carries more information than the coin.
