About Daily Radar

A small patch of the map each day: name cities to light up the rest in 5 minutes. Each day's patch is somewhere new in the world, the same for everyone, with five minutes on the clock.

A city-naming game played on a map. Every city you name draws a circle, and every big city inside it lights up, so a few well-spread names can cover a whole country. It rewards knowing where cities are, not just what they're called. If you've played HugeQuiz's City Coverage quizzes, it's the same idea, with a daily round as well as the whole world and every continent. (Geographys isn't affiliated with HugeQuiz.)

How it works

1. 1Type any city. A name is credited the instant it's valid.
2. 2Every city you name draws a circle, and every city inside it lights up.
3. 3Big, well-spread cities cover the most ground. Hint rings the biggest city that's still dark, and pressing it again moves on to the next biggest.
4. 4Your score is the share of cities you covered. The daily has a 5-minute clock; the anytime modes don't.

Tips

• Start with cities far apart. Two big cities next to each other waste most of their circles on the same ground.
• Look for the dark patches. Regions you haven't covered usually have a big city or two you've forgotten.
• Name regional centres, not just capitals. They light up the towns around them.
• When you're stuck, use the hint. It rings the biggest city still dark, which is usually the most useful one to name. Don't know it? Press again for the next biggest.

Questions

Where do the populations come from?

National statistics offices and the UN's World Urbanization Prospects. The credits page lists every source.

What's the difference between the daily and the other modes?

The daily has a five-minute clock and the same map for everyone. The anytime modes have no clock, so you can cover a region at your own pace.

Which maps are there?

The world and the US are free. Supporters also get continents and country maps, each with its own daily.
