RULES

Normal irregular anti-knight sudoku rules apply - digits (1-9) may not repeat in any row, column, region, cage/pentomino, NOR a chess knight's move away. Additionally:

• Tile the grid except for the, CTC shaded area, with one of each of the twelve pentomino shapes (refer info below).
• The digits in a pentomino must sum to a multiple of the pentomino's english alphabet position - example: digits on an 'I' must sum to 9, 18, 27, 36 or 45.
• A much harder version of this puzzle, without marked regions, is also available: https://sudokupad.app/nfcwfdye3o
• A pentomino is five orthogonally connected cells forming one of twelve unique shapes (whether they are flipped or rotated) represented by the letters: FILNPTUVWXYZ Refer to: https://simple.wikipedia.org/wiki/Pentomino
