How to play The daily expedition

01

Open today’s expedition

The UTC date selects a reproducible set and order for this game version. Everyone using the same version and date receives the same questions.

02

Change your thinking

Each round states its own rules before you commit. You will move from geographic deduction to wildlife knowledge and historical reasoning.

03

Share the discovery

Finish five rounds, copy a spoiler-free result and challenge link, or revisit low-scoring rounds as separate review practice.

THE RULES, UP FRONT

How scoring works

Five rounds, up to 5,000 points. Each round uses its own published game rule: outline attempts, species clue penalties, habitat accuracy, year proximity or event chronology. The daily seed changes at 00:00 UTC.

MORE THAN A SCORE

What you’ll discover

Practice several connected skills rather than only recalling place names. Answer explanations link geography, animal adaptations and precisely documented moments in natural history.

A few clues for your first game

  • Read the rule when the round type changes; not every game uses distance scoring.
  • Finish at your own pace: there is no shared countdown.
  • Use mistakes practice after the result to turn an uncertain answer into a lasting connection.
BEFORE YOUR FIRST DISCOVERY

Questions about this game

Do the questions change every day?

The UTC date changes the deterministic selection and order. Each subject follows a rotating deck: 30 countries, 23 animal mysteries, 19 habitats and ten dated events. Adjacent days have different targets in these four subjects; the finite bank eventually repeats. Chronology rounds avoid reusing that day’s year-answer event when possible.

Does a challenge link let friends play together live?

No. It reproduces the same questions and order for independent play on a compatible version. There is no live matchmaking or shared leaderboard. Shared links open this game on DodoHistory.

Will review practice change my daily score?

No. Review is separate practice for rounds below 800 points. It does not overwrite the original personal record or masquerade as a shortened version of the original shared challenge.

PLAY WITH CURIOSITY

The evidence behind the fun.

Eight game mechanics plus a daily remix. Every answer has an explanation and source. The 82 question records and country targets rotate and eventually repeat; they are source-checked on October 31, 2026, not independently expert reviewed.

Country shapes are generalized modern Natural Earth boundaries (public domain). Distances and directions in Shape of the world are to representative country coordinates, not border distances. Hot & cold Earth uses nearest accepted land boundaries with a 40 km tolerance. It is a geographic puzzle, not an animal range map.

Scoring: up to 1,000 per round. Shape and hot/cold: 1,000 on attempt one, then minus 150 per extra attempt, up to six guesses. Species: minus 200 per extra clue; a wrong committed answer gets zero. Year: 1,000 × exp(−absolute year error / 30), rounded. Habitat and chronology: 1,000 correct, zero otherwise. Memory: 5,000 minus 150 per move beyond five, floored at zero. All rules appear before committing.

Use touch, mouse or keyboard. Globe movement is optional; a 2D map, place selector and coordinate form are available. Reduced motion disables reveal movement. Sound is off; there are no autoplay effects or speed bonuses.

Challenge links reproduce the same question set and order on compatible game versions. They are local, unranked and not tamper-proof. Share the link to invite someone to play the same set on DodoHistory.
