What is a timeline game?

The core idea

A timeline game gives you an event and asks you to position it in time. You are not asked to retrieve a date from memory; you are asked to reason your way to one. That difference matters, because most people who cannot name the year of the first Moon landing can still reason that it came after the Second World War, after the first satellite, and before the personal computer — and that chain of reasoning lands them within a few years.

The result is a game you can play about subjects you have never studied. A round about a dinosaur, a printing press or a video platform all reduce to the same move: find the era, then narrow down. Scoring by distance rather than by right-or-wrong is what makes that possible, because a thoughtful near miss earns most of the points a perfect answer would.

The main formats

Ordering games give you a handful of events and ask you to sort them, oldest to newest. They are quick to grasp and they test relative sequence, but they never ask you to commit to an actual date — you can win one without knowing whether the set spans a decade or a millennium.

Placement games, the format QuoAnno uses in Endless and Daily, give you a continuous timeline and let you put a marker anywhere on it. This is the most demanding version, because there is no shortlist to work backwards from, and it is the one that most directly builds a sense of scale.

Multiple-position games sit between the two. Four Points shows four unlabelled spots on the timeline and hides every date until you commit, so the choice stays about chronology rather than about eliminating an obviously silly option.

Card games — the tabletop lineage the genre grew out of — have you slot a card into a growing row on the table. They are social and tactile, and their constraint is physical: a table only holds so many cards, so the span stays narrow.

What separates a good one

Honest dates. Plenty of events cannot be pinned to a year, and a game that invents one to keep its scoring tidy is teaching you something false. A good timeline game stores the uncertainty and accepts any answer inside the supported range.

A scale that actually spans. If the earliest event is the Roman Empire, you are playing a game about the last two thousand years. Reaching back past the first humans, past the dinosaurs, to the formation of the planet demands a non-linear canvas — on a linear one, every human event collapses onto a single pixel.

Feedback that teaches. Being told you were wrong is worth little. Being told you were 340 years early, and shown where the event actually sits beside things you already knew, is what moves your next guess.

Graded scoring. If landing one year out scores the same as landing four centuries out, the game has thrown away the information that makes it a timeline game at all.

How QuoAnno plays it

QuoAnno runs on one continuous timeline from the formation of Earth to this morning, with events drawn from natural history, ancient and modern history, science, technology, space, art, film, music, the internet, exploration, archaeology and sport.

Endless has no cap and no daily limit. Four Points is the faster variant. Daily Mix gives everyone the same ten events for the UTC day. Live Party puts a room of people on the same question at once, and Challenge freezes a question order so friends can play it days apart. None of it needs an account — progress lives in your browser.
