- Four Color Sums: Clues outside the grid represent the sum of the digits placed in cells with the indicated color in the corresponding row or column.
- Pentomino Regions: Digits may not repeat in a pentomino.
Example Puzzle (5x5, 0-4)

Very unique logical ideas showcased in this puzzle. Classic Agent moments in the midsolve where I thought I'd broken things, only for a crazy option to be forced.

A magnificent puzzle. An incredible balance of difficulty and guiding. As someone without familiarity with the genre this did a great job of steering deductions even while clinging to its secrets.
