How to play

The board holds a hundred people, drawn as dots. Each round shows a rule at the top, like tap everyone with clean water, or tap everyone who can read. The people who fit are marked by colour. Tap all of them before the timer empties. Every correct tap scores. A wrong tap costs you time. Clear the round and the rule flips, the timer shrinks, and the colours reshuffle. Miss the timer and the round is over. It is a fast sorting game built on the same idea as the book: big numbers get easier to feel when you shrink the world to a hundred.

This is a single-player game built with vanilla JavaScript and an HTML canvas. It runs entirely in your browser, works offline once loaded, and saves your best score locally. Part of Hibranwar Arcade.
