Normal Sudoku rules apply.
Draw a path through some orthogonally connected cells, such that the path visits every box and never enters or exits the same box twice. Each time the path changes the box, the total number of cells it visits in that box is increased by 1, starting with 1 in the starting box.
The final cell of the path is in the same relative position in its box as the starting box of the path is in the grid.
A cell is called friendly when its digit is equal to its row, column, or box number. There are 27 friendly cells in the grid.
The path visits all friendly cells and enters no cages.
Adjacent digits on the path differ by at least 3.
