Play in Sudokupad

Hey everyone! This puzzle uses the same rule set as my previous In or Out puzzle. It took weeks to work out a combination of regions and cages that resolved to a single solution without guessing. I hope that you give it a try.

These puzzles are a little cluttered, and require a logical approach that includes a dual cage and irregular solving process. Again I included space outside the grid to fill with possible combinations of digits that are in or out. The puzzle regions are also left uncolored so you can choose your palette. Below the puzzle rules I have included a diagram to indicate how boxes and cages correspond.

Rules:

Place the digits 1-9 in every row, column, and irregular region.

Digits in a cage do not repeat and sum to the number given. Each cage corresponds to a regular 3x3 box and contains every unique digit in that box.

Space is given outside the grid for pencil marks.

Diagram 1 shows a normal sudoku box region with every digit. A cage that includes every unique digit would have nine cells and total 45.

Diagram 2 shows a 3x3 box in irregular region sudoku. Since there could be repeated digits in this 3x3, this diagram shows one possible option. This cage includes every unique digit, has six cells, and a total of 32. Any cells out of the cage hold a duplicate digit. 3x3 boxes in this puzzle are similar to this example.
