CLOAK
Trace CLOAK from row 3, column 6. Move up to row 2, column 6 for L, then left to row 2, column 5 for O and left again to row 2, column 4 for A. Turn up one final time to row 1, column 4 for K. The path spells C → L → O → A → K and ends at the lone open cell in its row.
Its movement is up, left, left, up: two upward moves and two leftward moves, with two turns across three straight segments. It spans three rows and three columns, starts on a cell with three open orthogonal neighbors, and ends on a cell with one. For a precise comparison, the coordinate transcript is: 1 at row 3, column 6; 2 at row 2, column 6; 3 at row 2, column 5; 4 at row 2, column 4; 5 at row 1, column 4. This first route assigns five cells, leaving 24 open cells for the remaining words.
