Five moments from one life, as the game plays them: a final notice at twenty-four, the hospital with her mother, the wedding, a phone that is not answered at night, and a Saturday in the park.

five moments from one life, as the game plays them

What it is

You live a whole life, one choice at a time — from the small things to the ones that decide everything — and nothing is guaranteed.

Every outcome is rolled against the odds a real person would face. Studying harder improves your chances; it does not hand you the job. Skipping the doctor does not kill you, and it does not let you off either. The life you end up with is what those odds did with the choices you made.

Your choices move hazards, never certainties.

How it works

You do not choose where you start

A country, a household, a body. Nobody picks those, so neither do you. The childhood is yours to live from five, or to leave to the years.

The years pass whether you like it or not

Between decisions, time runs. People age, money moves, chances open and close while you are looking elsewhere.

Every outcome has a reason

When something happens, you can ask why — and see the chain of choices and the roll that led there.

One life at a time

You cannot keep a spare. Ending a life is a decision, and the record of it is yours to read afterwards.

Four ways in

Today's Life

The same life as everybody else

One world a day, the same one for every player on earth. A whole life in under twenty decisions and about ten minutes. Tomorrow it is somebody else's.

Simply Broken

Live somebody else's life

Step into a life already in progress, with its people and its unfinished business. What happens next has not been written.

From the novel Simply Broken by Opeyemi Olufunmi Michaels.

Random Life

Take the lottery

Born somewhere, to a family you did not choose. A childhood from five, if you want it, then seventy years of your own decisions, each one leaving its mark.

Match a friend

Same world, different choices

Invite someone into the exact life you were dealt — same start, same luck — and compare what the two of you made of it.

The real odds

Every roll in One Life starts from what really happens to people. These are some of the numbers, explained in plain English, with their sources.

On the phone too

The whole game works on a phone: the same lives, the same odds, the same seventy years. Pick it up on the bus and put it down again.

Start a life on a laptop and carry on from your phone — sign in with your email and it follows you. No password, and one life at a time wherever you are.

One Life on a phone: a Saturday in the park, and three choices beneath it.

Thousands of choices. One life.

Simply Broken

a novel by Opeyemi Olufunmi Michaels

One of the four ways into the game came out of a novel. Simply Broken is the story of Tinu, Tayo, Fola and Lara — four people who love each other, hurt each other, leave, return and forgive, and find that forgiveness does not put everything back the way it was.

But being broken is not the same as being finished.

It is finished and not yet published. The first three chapters are free to read now, and you can hear when the rest of it is out.
