How to play
Jade goes first. Select one of your queens, then slide any distance horizontally, vertically or diagonally through empty squares. From the new square, shoot an arrow along another clear queen line. That square becomes blocked forever.
You may shoot through or onto the square you just left. You cannot jump queens or arrows. The first player with no legal queen move loses. Queens are never captured.
The quick grove uses two queens per side. Classic uses four. Computer play uses a bounded mobility heuristic; it is beatable.
Keyboard: Tab to a square; arrow keys navigate, Enter or Space selects. H gives a hint, Escape cancels, U undoes your last decision. Progress saves on this device after every action.
