Pick a word from the list, then click a glowing cell — that's where a word can begin.
A split cell means two words start there: the top-right half places across, the bottom-left half places down.
Hovering a glowing cell previews how far the word would reach; a red wash means it won't fit there.
With nothing selected, click a placed letter to take that word back. Crossing letters other words still need stay put.
undo reverses your last move — placing or removing — and pressing it again reverses the undo (⌘Z works too).
define opens the meaning of the selected or last-placed word. The clock pauses while you read.
Click any empty part of the page to unselect.
A filled grid with no conflicts counts as solved, even if your arrangement differs from the intended one.
The chart: click an island to sail to its theme; the wind note sails you somewhere random. Pennants mark islands you've solved; the ship marks where you are.
