Desert and Polar Extremes Estimator

Estimate the scale of the world's driest deserts and coldest polar outposts.

Theme: Extremes · Difficulty: Hard

How the practice set is built

The Desert and Polar Extremes Estimator filters the curated dispatches through its matching rule and, when fewer than a full five-round set match, tops the set up from the deterministic generator. Scoring is identical across every category: pin rounds use great-circle distance, year rounds reward proximity to the founding date, and the stat dial scores how close your estimate lands.
