Flight Chain: Daily Puzzle

Become the connecting-flight planner — every single day. Flight Chain is a daily puzzle game built on real Japanese domestic flight schedules. Each day, tomorrow's flight schedule is revealed. Chain together flights that connect at the same airport to build your "flight chain" and predict the total great-circle distance you'll fly. Lock in your plan before 23:59 JST — once those flights have flown, your chain is scored against what actually happened, with results landing the following morning. ■ Simple to play Pick a departure airport, then connect flights one after another — as long as each connection leaves at least 20 minutes. Longer routes score higher, but a delay or cancellation can break your chain right where it stands. Check back each morning to see how your plan held up. ■ Chase the daily bonus Every day, one airport carries a bonus multiplier. Route your chain through it and every leg that touches it scores extra — plan ahead to aim for a big score. ■ More fun the longer you play • Tracks your daily play streak • Full history of past results, always there to revisit • Game Center leaderboards and achievements • iCloud keeps your progress in sync across devices ■ AI-assisted suggestions (supported devices only) On Apple Intelligence-capable devices, on-device AI suggests a few distinct route options and explains its pick. You can also ask a quick on-device AI chat about any airport. Everything runs on-device — nothing you type ever leaves your phone. ■ About the data Flight schedules and results are based on data from Japan's Public Transportation Open Data Center. This is an unofficial game and doesn't use any real airline names or flight numbers. Free to play. No personal data is collected. Tomorrow's flights are already scheduled — how will you chain them?
