My first non-9x9 sudoku puzzle. Hope you enjoy the snack!
Normal 4x4 sudoku rules apply.
Draw a 1-cell-wide snake of orthogonally connected cells in the grid. The snake starts in the top-left cell, visits every 2x2 box at least once, and does not branch nor touch itself orthogonally.
A cell is 'friendly' if its digit matches its row, column, or box number. The snake consists of all of the non-friendly cells and none of the friendly cells.
Solution code: Row 2 and then row 3

This belongs to the group of puzzles which I would classify as "discoveries". It is amazing that such a simple ruleset leads to a unique solution. Well done, yanggang!

A short, sweet snack. I sort of lucked into the solution, but it was fun nonetheless!

very cool, my first puzzle on this site. took me some time to figure out that the solution cannot be mirrored along the diagonal, after that it was pretty straightforward :D
