Word 1: BIT, the three-cell route
Form BIT from row 4, column 5. Move down to row 5, column 5, then turn left and finish at row 5, column 4. The letters read B → I → T. This compact route makes one turn, consists of two straight segments, and spans two rows and two columns.
Follow these positions exactly: 1 at row 4, column 5; 2 at row 5, column 5; 3 at row 5, column 4. All three positions are edge visits, and row 5, column 5 is the route’s single corner visit. On the raw board, both the starting and ending cells have two open orthogonal neighbors. Completing this word assigns three cells and leaves 15.
