This game uses the Human Development Index country table on Wikipedia, based on 2023 data published in 2025.

• Higher scores mean a place ranks better on the HDI composite.
• The index combines life expectancy, schooling, and income into one value between 0 and 1.
• Pick the place with the higher HDI score, or SAME when the listed values match.

HDI is one composite number, so it can clarify broad patterns while still flattening inequality, ecology, and internal regional gaps.
