1→2
From node 1 (center): move right 1, then begin outer spiral. The path winds from the center outward visiting every cell, reaching node 2 below center.
2→3
From node 2: continue spiral pattern down and to the left along the bottom row to reach node 3 at the bottom-left.
3→4
From node 3: traverse the entire bottom and right side of the board in a wide outer loop to reach node 4 in the top-right area.
4→5
From node 4: move left one cell to node 5 (nodes 4 and 5 are adjacent in the top row).
5→6
From node 5: complete the remaining cells by filling left side and inner paths, ending at node 6 at the bottom-left corner.
