TerraPoint

TerraPoint is a browser game about knowing where famous places are. Each round names a landmark, with a line of description and the country it sits in, and you find it on a 3D globe built from NASA Blue Marble satellite imagery, with sharper NASA GIBS tiles loading as you zoom in. At the deepest zoom it switches to Esri satellite imagery, close enough to pick out buildings.

A day's game is five rounds. You drag to spin the globe, zoom with the wheel, a pinch, a double tap, the slider or the plus and minus buttons, tap where you think the landmark is and lock in your one guess. The game then shows how far off you were and marks the real spot in green. Scoring follows the great-circle distance. About 50 km or closer earns the full 5,000 points, 500 km about 4,000, and 5,000 km only about 400.

The same five landmarks go to everyone, and a new set starts at midnight Pacific Time. When you finish, your score is posted to the daily leaderboard, where you can add any name you like; there are no accounts. A share card sums up your day, and the game keeps a day streak and your best streak in the browser.

After the daily run you can keep playing practice rounds, drawn from a pool of 500 landmarks that never includes the day's five. There is also a United States themed mode with 94 landmarks covering all 50 states. Only the first daily run counts on the leaderboard.

It suits players who like map games such as pin-the-place quizzes but want named landmarks rather than a street view to work out, and a short daily round that rewards zooming in carefully.
