Sortem

Sortem is a daily sorting game in the trivia family. Each challenge has a topic tag, a short instruction and a unit. On October 18, 2026 the topic was Temperatures: boiling water, the human body, liquid nitrogen, a lightning bolt, a wood-fired pizza oven, flowing lava and the Sun's surface, to sort by temperature in degrees Celsius, hottest first. The days before asked for boxing weight classes by upper weight limit and human bones by length, and other days use moons, countries, cities, foods and more.

You drag the rows into the order you believe and press Check Order. Each item then shows whether it is in the correct spot, which locks it in place, close to the right spot, or far off. A row of coloured dots under the board records each guess. Solving in one, two or three tries earns three, two or one stars.

A countdown shows when the next challenge arrives at your local midnight, the statistics screen tracks your daily streak, and an archive lets you play past days without affecting the streak. Results can be shared directly to social sites. It plays free in the browser with no account, and its consent notice says it uses no third parties and no ads.
