A cute 6x6 version of this puzzle "Shoelaces" was constructed for rangsk's "Adventure series" on YouTube. The series features small variant sudoku puzzles designed to introduce rules/concepts for beginners. A link to his playlist can be found here
Normal Sudoku rules apply. Place the digits 1-9 exactly once in every row, column, and 3x3 box.
Odd: Digits in shaded circles are odd.
Double Arrows: There are circles in the grid connected with lines. The sum of digits in the circles is equal to the sum of the digits on the attached lines. Digits are allowed to repeat in circles as normally allowed by other rules.
Quadruples: Quadruple circles are located on some cell vertices. Digits in the quadruple circles must all appear at least once in the cells touching them.
Play on SudokuPad
Solution code: Digits from Row 9, followed by digits from column 9 of the solve grid (18 digits, no spaces)
