I have made a few penguin puzzles, and am planning to make more. The rules are complicated so I made this puzzle for beginners. If you learn the rules, this puzzle should not be that hard.

Rules:

Normal 4x4 sudoku rules apply.

There are penguins running around in this sudoku. Each penguin has a corresponding number outside the grid next to the square they start in. The number is how many squares the penguins will visit, including the starting square.

A penguin will always move into another square if it is able to. It can only enter a square that is orthogonally connected to the square it is in. (So it never moves diagonally.) A penguin will never enter a square it has already been to. (A penguin will not stop walking simply because it has used up the steps in its clue, it has to be because it has no valid square to enter.)

When choosing between possible squares it can move to, the penguin will choose the square with the smallest number (Because penguins like it cold.) If there are two possible squares with the same smallest number, the penguin prefers moving horizontally (left or right) instead of vertically (up or down).

Example:

The penguin’s path is marked with red.
