Daily Ceteris
Rate itOne economics question a day, answered with a country in six guesses.
on ceteris.app

Daily Ceteris is a free browser game from EconCoaching that asks one economics question a day, such as which country is the largest producer of natural rubber. You have six guesses to name the country. In Normal mode each wrong guess shows its distance and direction from the answer; Hard mode leaves out the map hints. The answer comes with a short note on the economics behind it.
About Daily Ceteris
Daily Ceteris is a daily guessing game about economics, made by EconCoaching and its Everything Econ channels. Each puzzle has a number, a date and a difficulty label, and asks a single question whose answer is a country, for example which OECD country has the highest female labour-force participation rate.
You type a country and press Guess, and you have six tries. In Normal mode a wrong guess shows how far it is from the answer, a closeness percentage and an arrow pointing the right way, measured from the centre of each country, with green for hot, orange for warm and red for cold. Hard mode drops these geographic hints, so you have to work it out from the economics alone. The Economics hint button gives up to two clues about the answer's economy.
After the last guess the game reveals the answer with a short explanation, the data source behind it and a link to an article on the topic. You can share your result as coloured squares or as an image, and your stats keep a win rate and a win streak. The question changes at midnight UTC. The questions come from a fixed bank, so a long-time player will meet one again after about four months.
The Games menu on ceteris.app lists more of the same maker's games about countries and economics, each with its own daily puzzle and an endless mode. Daily Ceteris suits players who like Tradle or Worldle and want the reason behind the answer as well as the answer.

Tips
- Distances are measured from the centre of each country, not its capital, so large countries can read farther away than you expect.
- Your first guess can be a central country, so the arrow tells you which part of the world to search.
- Think about who produces or trades the most of the thing named in the question before you guess.
Questions
Is Daily Ceteris free?
Yes. It is free to play in the browser with no login and no ads.
Is the question the same for everyone?
Yes. There is one numbered question a day for every player, and it changes at midnight UTC.
What is the difference between Normal and Hard mode?
Normal mode shows the distance, a closeness percentage and a direction arrow for each wrong guess. Hard mode shows none of these, so you work from the economics.
