Rules

Standard Sudoku rules apply.

Fill each cage with a unique set of Pentomino (size 5) and Tetromino (size 4) Shapes.

Shapes of the same size may not be orthogonally adjacent within or between cages. The cells outside of cages are not considered a shape.

There may be no more than two of the same Pentomino shapes anywhere in the puzzle.

Digits do not repeat within a Pentomino or Tetromino except in exactly one place.

The sum of the digits in Pentomino shapes ranges from 13 to 34. The sum of the digits in Tetromino shapes ranges from 14 to 25.

Digits on lines form Palindromes.

Cells with a V between them sum to 5. Cells with a white dot between them are consecutive.

The digits in a cage sum to the number in the upper corner of the cage.

Solving the Puzzle

All steps can be made by deduction. No guessing or brute force is required. The individual steps are not overly hard, but there are quite a few steps, and quite a few rules to keep in mind. If you get stuck, I suggest carefully reading the rules again, to see if any of them suggest a way forward.

SudokuPad Usage Suggestions

The area outside the 9x9 Sudoku grid is scratch space for drawing polyominoes, if needed. Within the grid, representing polyominoes with center to center lines rather than colors will free colors up for other purposes. Letters or colors may be used to represent numbers whose values have not yet been determined. Good luck!
