Rules:
5x5 irregular sudoku rule applies, but the letters and regions are to be determined by the following rules:
The grid must be divided into five non-congruent pentominoes (i.e. shapes must be different even if reflected/rotated) and the letters to be placed are the letters that correspond to the five pentominoes in standard pentomino notation. (See: https://upload.wikimedia.org/wikipedia/commons/thumb/e/ed/Pentominos.svg/1200px-Pentominos.svg.png)
Circles mark letters that correspond to the shape of the region it is in.
5x5 irregular sudoku rules: Fill in exactly one letter from the five-letter bank in each cell such that each row, column, and 5-cell region must contain each letter exactly once.
Solution code: Row 1, then row 5

Nice concept! Btw no digits are to be placed, but 5 letters are to be placed corresponding to the 5 distinct pentominoes and satisfying sudoku rules.
REPLY: you're right! i'll fix the wording
