DRAG the SCREEN to rotate the globe HOVER over a City to see its Name ARROW KEYS or SCROLL WHEEL or ZOOM SLIDER to Zoom In and Zoom Out This project includes 374 locations! Each day, one city will be secretly chosen at random and you must find it! PRESS a city to color it and see its distance to the secret city [ Note as of 3/18/2026: Scratch Cloud Variables do not save between sessions, breaking the leaderboard. If you would like your score to save between sessions, use Turbowarp: https://turbowarp.org/1284999546 ] If you find today's city fast enough, you may set the cloud record! Make sure cloud variables are working: https://scratch.mit.edu/projects/1233851863/ If cloud vairables are down on Scratch, try Turbowarp: https://turbowarp.org/1284999546 An Arrow pointing to the secret city appears after 30 Seconds to help! If you would like to add your own cities, you can remix the project and add more blocks under the "Init Cities List" custom block in the format "Name", latitude, longitude If you like this project, consider ❤️⭐ Feedback is appreciated! #puzzle #daily #mobile #pen #geography #search #earth #3D NOTES & CREDITS: . All sound from Pixabay . This project uses absolutely no costumes except the thumbnail . Cloud variables and daily city are updated automatically using the "days since 2000" block . Uses Equirectangular Projection To Map Sphere . Uses C = sqrt(A^2 + B^2) for sphere scanline rendering, which appears to be faster than Bresenham's algorithm on Scratch . Uses a 2-angle gimbal lock chained rotation engine, which I believe is faster than alternatives [not tested], because it uses 8 multiplications per vector while quaternions use 32 and matrices use 9 .
