How it works
One screen, four decisions, zero setup.
Coin Flip Online is deliberately small. There is no account to create and no configuration to get wrong — but there is more control here than a plain Heads-or-Tails button gives you.
Try it nowThe process
From zero to a decision in four steps.
01
Choose how many tosses decide it
Single flip is the classic call — one toss and you are done. If the stakes are slightly higher, switch to Best of 3 or Best of 5 and the tool keeps score for the whole contest until one side reaches the winning total.
02
Optionally rename the two sides
Open “Customize the two sides” and type whatever makes sense for your decision. Yes and No, Home and Away, Team A and Team B, Pasta or Salad. The coin faces, the scoreboard and the history badges all pick up your wording immediately.
03
Press Flip — or just hit Space
The coin launches with a real 3D arc, spins through several rotations and settles into its landing. If your system is set to reduce motion, the spin collapses to an instant result instead.
04
Read the verdict and the proof
The winning side appears in the result line, along with the raw entropy value that produced it. Your flip count, Heads/Tails split, current streak and the last fourteen tosses are updated underneath.
