Normal sudoku rules apply. Place the digits 1-4 once each in every row, column, and 2x2 box.
Digits along an arrow sum to the number in the attached circle.

Solution code: Enter the digits of row 1.

The arrow logic is cool but its hard to tell if the arrow bends or not

You get two different solutions to this one, depending on if you interpret the arrows with circles in column 4 as being straight lines or if they bend and change direction after r3c2.
