How to Estimate Years and Dates in Plain Game

Most Plain Game questions reward a good sense of scale. Calendar-year questions work differently. When the target is a year, your points depend on how many years away you are, and the ratio rule from other rounds does not apply. Understanding this changes how you should guess.

How year questions are scored

For a year question the base score is round(100 × exp(−years_off / 16)). Only the exact year earns the 25-point Bullseye bonus. These base points show how quickly a miss costs you:

The fall-off is gentle compared with ratio rounds. Being ten years off still returns more than half the points, so a decade-level guess is worth making even when you have no idea of the exact year. The full rules, including the label for answers more than 60 years away, are on the scoring page.

Why you should never skip a year question

Because a guess in the right decade scores around 50 to 90 points, a rough answer almost always beats leaving the round to time out. A timed-out round earns nothing and still lets your plane drift down. Even if the subject is unfamiliar, work out a plausible window and pick the middle.

Build a short list of anchor events

Years are easiest to place relative to events you already know. A small timeline in your head, about a dozen anchors, is enough:

• The first mass-market home computers in the late 1970s and early 1980s
• The World Wide Web becoming public in the early 1990s
• The turn of the millennium in 2000
• The smartphone era taking off around 2007 to 2010
• The pandemic years beginning in 2020

When a question names an object or a person, ask which anchor it sits before or after. If an invention needs electricity, it is after the late 1800s. If it needs a satellite, it is after the late 1950s. If it relies on a touchscreen phone, it is after the late 2000s. Each constraint removes decades.

Use lifetimes and generations as rulers

Lifespans give you a second tool. If someone was famous as an adult at the time of a known event, subtract thirty to sixty years to bracket their birth. If a building or a bridge is said to be centuries old, the style and materials can help split medieval from early modern. You are not trying to recall the exact year; you are trying to cut the window from two centuries to two decades.

Pick the middle of the window

Once you have a window such as 1920 to 1960, answer with the middle, 1940. Under this scoring the expected loss grows smoothly with distance, so the centre of your belief is a sound choice. Only shift away from the middle when you have a specific clue that favours one side.

Years versus ratios in the same flight

A flight mixes both kinds of question, so check the unit before you answer. If the prompt asks for a calendar year, answer with a four-digit year, not a count of years ago. If it asks for a quantity, apply the scale-first approach from why twice as big and half as small score the same. The FAQ explains what the game accepts as an answer.

A two-minute practice drill

1. Open a practice flight, not the daily one, so there is no pressure on your streak.
2. On each year question, write down your window and your answer before checking the reveal.
3. After the reveal, record the gap in years and which anchor you used.
4. After five flights, look for a pattern in your own gaps, such as always guessing too recent or too early.

Keeping those notes turns a few minutes of play into measurable progress. When you are ready, start a free flight on Plain Game and see how close you can get.
