Here’s an archival of some of my Sudoku puzzles. Also check out my 2020 Pax West Online SpyParty-inspired Sudokus.
Hidden X-Sums & Sandwiches
Sudoku rules apply. Clues outside the grid are either Sandwiches (with the number giving the sum of the digits between the 1&9), or X-Sums (with the number giving the sum of the first X digits, where X is the first digit from that direction, inclusive). In cases where two clues are given for a row or column, there is one of each type.

Twins Sudoku
Sudoku rules apply. Along the marked diagonal, no digits repeat. In the Killer cages, with the dotted lines, the number given in the corner gives the sum of the digits in the cage. Digits may never repeat within a cage. The red zones are direct, unrotated clones of each other. One unknown digit acts like a chess Queen, and will never see itself along the diagonal of any length. This unknown digit also appears within every killer cage.
