How to conquer
Drag through neighboring letters in any of eight directions, then lift to submit. Aim through letter centers; shared corners are neutral. Slide backward over the previous letter to undo it. A tile cannot be reused in the same word.
Find at least 3 letters. A word can be discovered only once, even by another route. Claimed letters remain usable. Fortified tiles need a valid word of 5+ letters; shorter words still enter your field notes and can claim ordinary tiles.
At 7 claimed tiles a 4×4 board reveals 5×5. At 17, eligible expeditions reveal 6×6. Some fortified paths become easier after a reveal.
Bronze unlocks the next location. Stay to earn Silver and Gold, or return to the map and resume later. Replay resets only this expedition's current words and territory, keeping best medals and campaign unlocks.
Tap mode: tap a path, then Claim word. Keyboard: arrows move focus, Space selects, Enter submits, Backspace undoes, Escape clears.
