For now, we’re using the hundreds of datasets compiled by @ourworldindata.org

They source data from the World Bank, FAO, UN, WHO, and more, all consistently formatted, which makes it easy for us to connect to their API and use the data with just a few filters.

Once you have played (win or lose), you can share your results with friends or post it on social media.

A personalised chart will show your guess history without revealing the countries, so it won’t give your friends any hints!

You can also check your stats and start building a streak! It might look a little empty for now since we’re only 4 days in, but I’m excited to see how it will grow over the next weeks!

You can log in with Google to ensure your scores are saved and play across multiple devices using the same account

I’ll explain a bit more some of the functionalities and what’s happening behind the scenes here now that the game is live!

If you didn’t play on a previous day, don’t panic! You can access the history to play past games and also see how many tries it took you to succeed on previous days.
