Each number says how many consecutive squares to fill. Separate groups with at least one blank. Tap to cycle blank, filled and crossed; right-click crosses. Keyboard focus stays with the rebuilt board or palette after a move. If that control becomes unavailable, focus moves to an available choice; completing the puzzle leads to Next level. Composing input and keys already handled by another control do not trigger game moves or Undo; Ctrl/Cmd/Alt shortcuts stay native.
