GeoSlice

GeoSlice is a daily geography puzzle about where people live. The map shows a real place, and your task is to cut it into pieces holding equal numbers of people. The puzzle size changes from day to day on purpose: one round may be a close-up of a single country, another a large part of a continent, and the day's rounds always span at least two continents.

There are three ways to cut. Halves gives you one line to drag and rotate until you think each side holds half the population. Thirds puts three spokes around a centre point, and Quarters two lines locked at right angles. When you lock in, the game shows the real split from WorldPop's gridded population estimates and scores the round out of 100. A green dashed line then shows the single adjustment that would have done best.

The daily is free and needs no account. Stats and streaks are kept in your browser. A free account puts you on the leaderboard and earns XP for daily play. A weekly challenge measures something other than people, such as animals, volcanoes or airports. A paid Premium plan adds the archive of past days, unlimited rounds and modes for any country, US states, UK counties, Canadian provinces, Australian and Indian states and world regions.

GeoSlice is made by Tom, known as GeoTom, a one-person maker who also runs the flag game Flagpie. The site now carries two more daily games beside the splitting modes. Inner Circle asks you to draw a loop around a set number of people, and Census drops a shape on the map for you to guess how many people live inside it. Each has five rounds a day.

It rewards a feel for where cities cluster: a line through empty desert barely matters, while a line past a single megacity can swing the whole score.
