Fly World

About Fly World

Fly World is a real-time flight simulator you can play straight in the browser, no install or account needed. Pick an origin and a destination and the game draws the real great-circle route on a globe, then flies it while day and night move across the map based on the sun’s actual position. In-flight events, nearby sights and country-crossing banners turn a simple transit into something that feels like a short trip.

Arriving successfully earns that country’s passport stamp. To keep stamps meaningful, only flights completed entirely at 1x, 10x or 30x speed qualify — using 60x or faster, or the preview-only highlight mode, still shows the result but without a stamp. Completing the daily route, which changes every day, builds a streak, and flights occasionally divert to a different airport so no two trips feel identical.

How to use

1. Let the game auto-detect your origin, or pick one, then choose a destination on the map.
2. Pick a speed and start flying. 1x, 10x and 30x qualify for a passport stamp; 60x, 3600x and highlight mode are for a quick preview only.
3. During the flight, check in-flight events, nearby landmarks and the countries you pass over.
4. On arrival, your passport gains a stamp, and you can see total distance flown and cities visited.
5. From the result screen, build a share card to save as an image or share as a link.

Passport data and storage

Your passport, visited cities, streaks and daily-route progress are stored only in your browser’s local storage — there is no server or account, so no personal data is collected, and clearing browser data resets your progress. The game file itself is set to noindex to avoid duplicate search results, with this page serving as the canonical URL for search engines.

Mobile support

Fly World works on both desktop and mobile browsers. The map is built to fill the screen regardless of aspect ratio, so tall phone screens don’t show empty bars above or below the map. You can drag and pinch-zoom the map with touch, and the Korean/English toggle works the same way on mobile.

Choose a quick preview or a stamp-earning flight

Use Highlight to preview a route quickly, or complete a flight at a qualifying speed to collect a passport stamp. Follow the great-circle arc on the globe alongside country-crossing notices to examine how a journey crosses the world.

Frequently asked questions

Why did I arrive without earning a passport stamp?

The entire flight must be completed at 1x, 10x or 30x. Speeds of 60x or above and Highlight mode are previews without stamps.

Is day and night just a fixed background?

No. It follows the real-time position of the Sun, while the flight follows a great-circle route on the globe.

Can I continue my passport on another computer?

Passport, visited cities and streak records stay in the current browser and do not sync automatically between devices.
