How to build a valid connection
Start from the airport on the puzzle card and choose an available outbound flight. Each next leg must depart from the airport where the previous flight arrived. Continue connecting through real airports until the itinerary reaches the named destination without crossing the day's budget or total-time limit.
Budget and elapsed time shape the route
The shortest-looking path is not always the best answer. A direct or one-stop option may be expensive, while a longer chain can consume the time cap. Layover asks you to balance airfare, flying time, and connection time instead of solving a simple line on a map.
Daily challenges reward creative itineraries
Every puzzle includes three extra objectives, such as using a particular aircraft type, passing through several countries, or finishing beneath a tighter time threshold. Reaching the destination completes the basic route; clearing all three challenges produces the stronger leaderboard result.
Real routes, puzzle-sized choices
The available legs come from airline schedule data, so connections reflect routes airlines operate rather than imaginary links between nearby airports. If you would rather identify a hidden route than construct one, play the daily flight guesser. For train connections, RailPass uses a related network-planning idea on rail lines.
