How to play

• Guess the hidden year. The first clue is a hard one, and is accurate only to the correct year.
• After a miss, the next clue is a time range that includes the hidden year. Guess inside a narrower range and you skip straight to it.
• When the ranges run out, each clue is accurate only to the hidden year.
• Each guess is underlined: yellow if the guessed year is within the next time range, grey if it's not, green if it's the hidden year.
• You get six guesses.

FAQ

When does a new departure arrive?

At midnight in your own time zone. Everyone gets the same year on the same date.

How is the score worked out?

It's out of 1,000. Boarding on guess one is worth 1,000, then 800, 650, 500, 350 and 200. Each miss adds up to 25 for how close it was, so a near miss on a day you don't board still scores.

What do the underlines on my guesses mean?

Yellow means the guess landed inside the next time range. Grey means it didn't. Green is the hidden year.

Why was my guess refused?

Guesses outside the years shown at the top are refused and don't cost a turn, because the clues have already ruled them out.

Who am I ranked against?

Everyone who has finished today's departure so far. Only your first finish each day counts.
