How to play

Seven prompts a day, the same for everyone. Any valid answer counts — the fewer people think of it, the more it’s worth.

1

Answer in the fog

A prompt surfaces through the fog. Type any valid answer — if it doesn’t count, we tell you why and you can try again.

2

Launch it

Your answer becomes a ball of light and is slung into the sea. The fewer people think of it, the further it flies.

See who thought alike

Find out how many people said the same, then explore everyone else’s answers — each one has a fact card.

The rarer, the deeper

Each prompt is worth 0–100 points: the fewer people who gave your answer, the more it scores — and the deeper it lands. Real numbers from the prompt “Name a fruit”:

The exact formula

points = 100 × ln(100 ÷ share) ÷ ln(2000), capped at 100. An answer fewer than 1 in 2,000 players give scores the full 100; seven prompts make a perfect 700.

Rules

25 seconds each

If time runs out before you give a valid answer, that prompt scores 0.

Must be on the list

Your answer has to fit the prompt. Lists are built from encyclopedias, dictionaries and other references; if an answer doesn’t count we tell you why, and you can try again.

Forgiving spelling

A one-letter typo or two swapped letters are still recognised, and common alternative names and plurals count.

You can appeal

Think we got it wrong? Tap “I think this should count”. We check every appeal by hand and add valid answers to the list.

Streaks and dive buddies

Play each day’s dive on its day to grow your streak; miss a day and it starts again. Streaks of 1, 3, 7, 14 and 30 days each unlock a dive buddy. Archive games don’t count towards your streak, but they are saved to your logbook.

Playing with friends

After all seven, tap “Challenge a friend” on your journey screen and send the link. Your friend plays the same dive and sees both of your answers side by side at the end.

FAQ

Is Oddex free?

Yes. There’s nothing to buy and no account to create — open the page and play.

When does a new puzzle come out?

Every day at 00:00 UTC. Everyone in the world gets the same seven prompts, so you can compare with friends.

Where do the percentages come from?

Each answer starts with an estimate of how many people would think of it, based on how familiar it is. As people play, their real answers are blended in, so the numbers move towards what players actually say.

Why was my answer rejected?

Either it isn’t on that prompt’s answer list, or we couldn’t recognise the spelling. If you’re sure it should count, tap “This should count” under the message and we’ll check it by hand.

Do archive puzzles count towards my streak?

No. Your streak counts the days you played that day’s puzzle. Archive games are still saved to your logbook.

Is my data private?

Your streak and scores are kept in your own browser. We store each answer with a random anonymous ID so we can count how many people gave it — no name, email or account.
