jl3377 is a self-contained tropical voyage puzzle where every route is drawn by hand across a living sea chart. You leave harbor on a Philippine bangka, thread open water, storms, reefs, and free trade-wind lanes, and dock at islands only when the path you plotted actually reaches them.
Each stage is a fresh chart. Fuel is limited, so the same islands can be cleared in a wasteful line or in a tight course that earns three stars. Treasures sit on the water itself and only count if the boat sails over them. Later stages ask you to visit numbered islands in order, which turns a simple path into a planning puzzle. A better boat adds a little extra fuel, and coins from clean voyages, quizzes, and character quests pay for the next hull.
What you discover stays with you. Every island you reach is stamped into an interactive travel journal with the date, your own captain note, and the relics you brought home. Local characters hand out quests tied to those finds. A timed island quiz tests what you picked up along the way, and a Discover desk keeps real island facts, festival dates, and Filipino phrases you can flip and learn.
jl3377 keeps the whole voyage on the device: no account, no ads, and no progress stored anywhere else. The chart, the journal, and the fleet are yours to reset or keep.
