Four cells with two turns
For FOOD, begin at row 4, column 6 and move left to row 4, column 5. Turn upward into row 3, column 5, then go right to row 3, column 6. Those four cells read F → O → O → D, with no diagonal step or skipped position.
Read the numbered sequence as 1 at row 4, column 6; 2 at row 4, column 5; 3 at row 3, column 5; 4 at row 3, column 6. The route spans two rows and two columns, changes direction twice, and forms three straight segments. It visits two edge cells and no corner cell.
