Meet your world. Home is now a globe, and every place you get right lights it up: in any quiz, the Daily or a multiplayer game. Turn countries green. A country goes pale green with your first place there and full green at 10 places, or when you name it. Your places raise your level, and NEXT shows you which country to turn green next. Tap a country to see its quizzes. Search the globe for a place or a quiz. Open a quiz in your Passport to see its places on the map, and tap Your move to jump straight to the games waiting for you. Your globe syncs through iCloud, so your iPhone and iPad show the same world. Packs are now called quizzes. Plus small fixes and polish.
