Your progress no longer lives on just one device: open your account and link a second phone or tablet with a short code — everything you've learned, your streaks, your records and your World Tour journey come along and stay in sync from then on.

World Tour is here, and it's the new heart of the app: one journey around the globe, played one stage at a time. Pick a continent on the world map, take on a short round of countries, capitals, landmarks and mountains, and watch the map light up behind you as you travel. Every level is scored on speed and accuracy — a flawless run earns three stars — and the next stop is never more than a few minutes away. Along the way you'll now see photos of the places you're guessing, the colored map has become the default, and the whole app got fresh artwork and a new set of buttons. iPad finally gets a proper layout in every orientation, too. Have a good trip!

Two new games land in this update. In Match Point, you tap every country on the map that matches the clue — wrong taps cost a life, so look before you leap. In The Link, it's the other way around: a handful of countries lights up and you figure out what they have in common. Your daily streak also got a proper home: a badge on the Home screen shows at a glance whether you've played today, a shield covers one missed day, and there are milestones to collect along the way, little celebrations included. To top it off, the whole app got fresh new artwork. Have fun!

Say hello to Border Hop, a brand-new way to play: start in one country and travel the world one shared border at a time, hopping from neighbor to neighbor until you reach your goal. It's part geography, part puzzle, and surprisingly hard to put down. I also gave the rest of the app a round of polish and squashed a good handful of bugs along the way.

This update adds two new games. In Landmarks, you guess the country from its famous landmarks; in Silhouette, you guess it from its shape alone. The rest of the app has a refreshed look as well.
