This puzzle was set at an in-person event at SudokuCon in Boston where I met ruthenia and Soleil and introduced them more or less in setting Sudoku. The idea for this puzzle came from the 'just one cell' event, where the goal was to get just one cell in an incomplete sudoku-grid. Those little snacks felt like break-ins to normal puzzles and we took and modified three of them in our puzzle. Many thanks to clover, who set most of the killer-snacks. Many thanks to tallcat for his testsolve and KNT for helping out in our own testsolve.

Rules:

  • Normal Sudoku rules apply
  • Digits in cages may not repeat and must sum to the given total in the top left corner.

Solve online: Sudokupad

Solution code: row 2

A gauntlet. It has been run. Very intriguing echoes of last weekend's 'Just one Cell' competitino.

For about six digits I thought "Why is this 3 stars?" Then I got mired in chipping away here and there - I may have even missed some intended logic. But I eventually freed myself and reached the end.

Lovely stuff. I found the beginning to be easier than 4 stars, but the mid-solve was quite subtle. Thank you very much for this fun collab, ruthenia, Soleil and ICHTUES!

Cracking the code in Boston. Puzzle is fairly straight forward. Code is harder!
