The Best Settings for Your First 1 in 8 Billion Run

The default combination is the right one for most first runs. Here is why, and when to change it.

26 October 2026 5 min read Editorial team Settings · First life

The first screen of 1 in 8 Billion has four settings and no explanation of which combination is a good first run. The short answer is the default: Today, Babies born now, About 1 hour, and the optional birthplace field left alone.

This note explains why that combination works, and when you should change it.

Setting Choose Why
World Today Current statistics, the baseline the game is designed around
Draw Babies born now The default birth weights; India is about one in six
Pace About 1 hour Enough time to read decisions without a marathon
Actual birthplace Blank A comparison, not an input; add it only if you want the mirror

This is not the only way to play. It is the least confusing way to learn the game.

Why Today first

The world setting changes the statistics the life runs on. Today uses current data and holds it for the whole life. The past uses a historical year and runs through what followed. The future starts now and runs into projections.

For a first run, Today gives you a stable baseline. The country table numbers, the birth card and the life record all refer to the same world. A past life adds a second variable before you have learned the first one.

The past is worth trying later. It is a different game: higher child mortality, shorter schooling, lower income, and real historical events. The developer’s own copy warns that a past world can include wars and mass killings. Save it for a run where you want that weight.

Why Babies born now first

The draw setting is the one players misunderstand most often. Babies born now weights each country by its annual births. The 8 billion alive now weights by population.

The birth mode is the default, and it is the mode the phrase “one in eight billion” most naturally suggests: a new person arriving now. India is 17.60% of the table, about one in six. China is 6.75%, Nigeria 5.69%.

Population mode is not wrong; it is a different question. China is much larger by population. Nigeria is much larger by births. Try it as a second run if you want to see the other shape.

Do not read the first draw as a verdict

A first run in a country you did not expect is not a bad setting. It is the draw doing its job. The guide’s birth odds page explains why the table is top-heavy.

Why one hour first

The pace options are About 30 minutes, About 1 hour (the default) and About 1.5 hours. They are the time to reach the country’s life expectancy, not the age at death.

One hour is the middle for a reason:

  • At one hour, a game year is about 40–60 seconds at 1×. That is enough time to read a decision without the life running away.
  • At 30 minutes, a year is roughly 20–30 seconds. Good for a demo or a classroom, but easy to miss details.
  • At 1.5 hours, a year is roughly 60–90 seconds. Good for a slow, immersive run, but long for a first session.

At 16× speed, one hour becomes about 3.75 minutes to life expectancy. The speed control is separate from the pace; you can keep the one-hour pace and fast-forward the quiet years.

The optional birthplace field

The Where you were actually born field is a comparison. If you set it, the birth card shows the simulated child next to a child born in the same second in your country. It compares life expectancy, under-5 mortality, expected years of schooling and GDP per person.

It does not change the draw, the family, the country or the ending. It is saved on your device only. The game has no account, so it does not follow you to another browser unless you move your lives.

For a first run, leave it blank. Add it later if you want the mirror.

When to change the setup

You want a short demo

Use About 30 minutes and 8× or 16×. A life that reaches life expectancy takes about 30 minutes at 1×, or under two minutes at 16×, before pauses.

You want a historical life

Use The past, choose a year, and keep the birth draw. Expect heavier material and a different statistical world. Read the settings guide before you start.

You want the population shape

Use The 8 billion alive now. China becomes much more likely; Nigeria becomes less likely. The rest of the mechanics are the same.

You are teaching a class

Use the game’s classroom mode, not the normal screen. It has a separate entry, a teacher lab, a class code and a lesson guide. The classroom guide covers the setup.

What not to change on the first run

  • Do not choose a past world just for novelty. It changes too many variables at once.
  • Do not use Auto mode for a run you care about. It is a viewing mode.
  • Do not set the pace to 30 minutes and then complain the life was shallow. The pace is a choice; the depth is a consequence.
  • Do not expect the birthplace field to change the draw. It is a mirror.

A first-run plan

  1. Leave the settings on Today, Babies born now, About 1 hour.
  2. Press Be born and read the birth card.
  3. Press Begin this life.
  4. At school age, alternate study with friends, exercise and hobby.
  5. Open Spend & invest once a decade.
  6. Read the death record before starting again.

That is the whole setup. The rest is the life.

Questions about this note

What is the best first-run setup in 1 in 8 Billion?

Today, Babies born now, and About 1 hour. It uses current statistics, the default birth weights and a pace that gives enough time to read decisions without turning the first run into a marathon.

Should I pick 30 minutes or 1.5 hours for my first life?

One hour is the middle for a reason. Thirty minutes is good for a demo or a classroom; 1.5 hours is good for a slower, more immersive run. The pace does not change the age at death.

Should I enter my real birthplace?

Only if you want the comparison. The field shows the simulated life next to a child born in the same second in the country you entered. It is saved on your device and does not change the draw or the outcome.
