A short history of coin flipping
Coin flipping is one of the oldest known decision-making methods. In Ancient Rome the game was called "capita et navia" ("heads and ships") — bronze coins featured an emperor’s head on one side and a ship’s prow on the other. In medieval Europe it was known as "cross and pile". Modern sports adopted it too: since 1892 the coin toss decides which team picks the side of the field in football, cricket and tennis matches. In American football, the coin toss is the ceremonial opening of every game. We’ve brought this centuries-old tradition to your screen.
Frequently asked questions
Is the result really fifty-fifty?
Yes. Each flip is decided by your browser’s cryptographic random number generator; heads and tails are exactly equally likely. Previous flips don’t affect the next.
What do heads and tails represent?
The two sides of the coin: “Heads” is usually the portrait/emblem side and “Tails” the side showing the value. Whichever side comes up is shown in large letters on screen.
How many times can I flip? Is there a counter?
As many times as you like. The counter under the coin shows how many heads and tails came up in this session.
Does it work on mobile?
Yes. It works on phones, tablets and computers; flip the coin with the button or by tapping directly on it.
What do heads and tails represent?
Heads is usually the portrait or emblem side of the coin; tails is the opposite side. In our tool, each side is shown with an equal 50-50 probability, mimicking a real coin toss.
Is the result really fair, exactly 50-50?
Yes. Each flip is decided by your browser’s Web Crypto API cryptographic random number generator. Previous flips do not influence the next; every result is independently 50% heads, 50% tails.
How many times can I flip? Is there a counter?
Unlimited flips. The counter below the coin shows how many heads and tails came up in the current session. The counter is only on your screen — nothing is stored anywhere.
Are the names and data I enter stored?
No. Everything runs only in your browser; the names and lists you enter are never sent to a server, stored or shared with anyone. When you close the page, this data is gone.
Does it take up storage on my device?
No, it takes up no storage at all. Online Kura is not a downloaded app; it runs entirely in your browser and nothing is installed on your phone or computer. If you like, you can add it to your home screen and use it like an app — with none of the storage.
How do I add Online Kura to my phone’s home screen?
iPhone (Safari): open the page, tap the Share icon and choose “Add to Home Screen”. Android (Chrome): open the three-dot menu at the top right and tap “Add to Home screen” (or “Install app”). Then you can open Online Kura like an app with one tap.
